ROLE

1. The Multitone RPR 563KGS is a UHF FM transceiver with selective calling and two-way
speech facilities. The unit can receive alphanumeric messages and can make selective
calling, speech and telephone calls. A sub-audio tone encoder/decoder is incorporated
ensuring that unwanted transmissions are ignored. The transceiver may be used in
simplex or duplex (telephone-style) mode.

2. Selective calling and telephone calls are made via a DTMF keypad. A reduced keypad
version of the transceiver, designated the RPR 563GS, (which does not have a DTMF
keypad) is available which is able to make limited telephone-style calls.

3. The transceiver is powered from a plug-in nickel-cadmium or metal hydride battery pack
which may be trickle or fast-charged via contacts in the base. Another set of contacts
in the battery pack allow the transceiver to be programmed, and allow absence
registration when used with absence/charging racks on Multitone systems.

4. Selective calls to the receiver are in Multitone Mk7 digital format which has a capacity
of up to 10,000 individual address codes. Visual alert is by flashing LED and eight
audible tone alert patterns (Beep Code) are available. Alphanumeric messages can be
displayed on a 14-character dot matrix Liquid Crystal Display (LCD).

5. The unit is housed in a Bayblend case which provides a lightweight but strong
construction. A pocket clip, holster and wrist strap lanyard are available as carrying
devices.

STANDARD FEATURES

Liquid Crystal Display (LCD)

6. The LCD provides a visual display of up to 14 alphanumeric characters (longer
messages are displayed in 14 character blocks). A backlight provides enhanced LCD
viewing under low light conditions.

Acoustic and Visual Alerts

7. A range of eight different audible tone alert codes (beep codes) are programmed as
standard. These alerts, when initiated, are accompanied by the illumination of an LED
to provide visual indication of a call. Speech calls are indicated by ringing patterns
which match the appropriate tone alert codes.

RPR 563GS/KGS

Page 1 - 3TM1187A Issue C

Message Storage

8. Up to five messages may be stored by the transceiver for review later. They are held

on a first in/first out basis.

Message Length

9. The maximum length of any received message is between 63 and 81 characters,

depending on whether beep code alpha and time stamp are in use.

Beep Code Alpha

10. Up to four beep codes may be reserved to trigger an associated alphanumeric message;

each message not exceeding 14 characters in length.

Automatic Speech Switching

11. Allows speech to follow automatically after an alert tone.

Battery Economy Circuit (BEC)

12. The radio channel is monitored periodically and when no activity is present the receiver

circuits are powered down, hence conserving energy and battery life.

Display Direction Control

13. The direction of the display may be changed to suit the way in which the transceiver is

carried.

Engineering Program Mode

14. May be used for reviewing programmed options in the transceiver. This feature is useful

for when carrying out engineering work on the system.

RPR 563GS/KGS

Page 1 - 4 TM1187A Issue C

OPTIONAL FEATURES

Permanent On

15. When a battery pack is fitted and the Permanent On option enabled, the transceiver
cannot be switched off.

Alert Duration

16. This is the duration of the alert tone at normal volume level. Options are 8s, 16s, 32s,
or continuous alert. This does not include the period of any `Silent' and/or `Quiet'
beep(s) that may be programmed. When a speech call is received, the programmed
option is overridden and the alert duration is reduced to 4s.

Escalating Alert (Escalert)

17. Defines the alert sequence, which is four seconds of silence (LED only), followed by four
seconds of Quiet beep, and the remainder of the alert as Full beep.

Extended Alert

18. Extended Alert is an additional alert sequence which acts as a reminder if the original
alert is not acknowledged. During Extended Alert, the LED flashes every two seconds,
and every two minutes two pips are emitted unless the transceiver is in Mute Mode.

Group Call

19. Group Call is an option which allows the receiver to be alerted as part of a group (or
team). If enabled, any call to the group will alert the user audibly. The Group size may
be none, 10 or 100 as required.

Call Comparator

20. Prevents the transceiver from reacting to an identical message received within a pre­determined period. Options are none, 30s, 120s, 300s or disabled.

Time-of-Day

21. When enabled, displays the time in hh:mm format. The transceiver uses an internal
clock which is synchronised by time information from the last valid Mk7 call.

RPR 563GS/KGS

Page 1 - 5TM1187A Issue C

Mute Mode

22. When Mute Mode is enabled, tone alert is suppressed when calls are received.

However, if a mute override beep code is received (triple pip or continuous pips), mute
is ignored and the transceiver responds with audible and visual alerts.

Program Volume Levels

23. On RPR 563KGS transceivers, the volume levels for beep tone, ring tone, telephone

speech, simplex speech and DTMF echo may be adjusted from the keypad.

Battery Low Indication

24. Visual and audible indication of low battery voltage indication are available as

programmable options.

Display Direction at Switch-On

25. Display direction may be changed for handheld or belt-worn operation. When the

transceiver is switched off, the current display direction is stored in EEPROM, unless the
battery is low. The default display direction is correct for handheld operation.

Speech Timeout

26. The speech timeout duration may be set for 10s, 30s, 300s, or continuous. The default

is 300s.

Address Digits Displayed

27. At switch-on, the number of address digits displayed is programmable between two and

five digits. The default is five digits.

Test Mode

28. This is for engineering use only. This feature limits the beep duration to one second and

defeats the call comparator.

System Number

29. The System Number for the Mk7 Digital format may be set to 0, 1, 2, or 3. The default

system number is 1.

RPR 563GS/KGS

Page 1 - 6 TM1187A Issue C

System Retry Interval

30. The System Retry Interval may be set to 30s, 45s, 60s or 90s. The default is 30s.

Line Service (RPR 563GS only)

31. The following Line Service options may be specified, call to a telephone extension,
broadcast to all Manual Control Units (MCUs), broadcast to specific MCU (1-9), teams,
and users. The default option is Broadcast to all MCUs.

Switch-On and Rack Message

32. A Switch-On message of up to 14 characters may be programmed. A Rack Message
of up nine characters, which is displayed when the transceiver is inserted into an
absence rack, may also be programmed. The default Switch-On message is
"Multitone 560" and the default Rack message is "Absent".

Switching On

7. Check that a fully-charged battery pack has been fitted. Press once. The

transceiver will initiate its switch on sequence as shown in Figure 4.

8. The address display will depend on the number of address digits option. When the

swit ch-on sequence has fi nished the transceiver enters the quiescent mode. If the
EEPROM is faulty, then a series of `E's will be displayed.

Quiescent Mode

9. This is the transceiver's normal operating state, when no calls are being made or being

rec ei ve d, no buttons are pressed and the backl ights are off. The displ ay shows the
highest priority status, and, if enabled, Time-of-Day information (hh:mm) derived from
the transceiver's internal clock..

10. When a call is received, the Alert LED will flash and, optionally, a series of beeps will

be heard. Press to cancel the alert and read the accompanying message.

RPR 563GS/KGS

TM1187A Issue CPage 2 - 6

Table 1: Message Display Formats

11. The displayed message comprises combinations of the foll o wing elements:

Element Example

a) Time stamp + space 12:00
b) Beep Code (Tone Only message) 4
c) Speech call Call ended
d) Beep code alpha Fire
e) Off-Air Message (Alpha) Please call reception
f) Message Terminator ** or **?

12. Unless in test mode, all messages are in one of the formats shown in Table 1.

13. The terminator **? is used when the call contains any suspect characters, or is
terminated early because of corrupt data. Otherwise the terminator ** is used.

14. When the total message length is 14 characters or less, it is displayed for the duration
of the aler t, if uncancelled. On cancel ling the alert the message is displayed for a
further 2.5 seconds.

15. When the total message length is greater than 14 characters, it scrolls through to the
end of the message at 1.25 second intervals, pausing for 2.5 seconds on the final
screen. This process continues until the alert is cancelled. On ca nce lling the alert the
message is displayed again from the beginning.

RPR 563GS/KGS

TM1187A Issue C Page 2 - 7

16. The tra nsce iv er is a b le t o rece i v e n e w ca lls duri n g a n a l e r t , a lthough receiver sensitivity

may be degraded. The new call takes over the previous call, which is placed in
memory. Preceding calls have "new" status unless cancelled during the alert.

Receiving a Speech Call (Selective Calling)

17. When a call is received, the Alert LED will flash and a telephone-style ringing tone will

be audible for four seconds. On receipt of sub-audio tone from the system the
transceiver will switch into speech mode. The message will be displayed as for a non­speech call. If the sub-audio tone is present, the speech audio channel switches on
immediately after the alert.

18. Press to cancel the alert and wait to hear the speech message. A further press of

the button cancels speech. If is pressed again, before the speech timeout period
expires, the speech channel may be re-opened.

19. The call is terminated by one of the following actions:

a) pressing
b) pressing
c) expiration of the transceiver speech timeout
d) a Mk7 speech termination signal from the system.

20. If the speech call has been rejected by two presses of , any subsequent pressing of

is assumed to be a new call request (see `Making a Call').

Receiving a Speech Call (Telephone Style)

21. Assuming a speech call has been received (as in paragraph 17) press to talk back.

The transceiver will be switched into telephone mode and the speech audio level wil l
dro p t o the programmed telephone speech level. The display di rection will be set to
read correctly for keyboard use. When the call ends, volume level and display direction
will return to their default settings. Extended alert and new status are cancelled.

22. The call is terminated by pressing , the speech timeout, or by a Mk7 speech

ter minat ion signal from the system. The transceiver will display the message "Call
ended".

RPR 563GS/KGS

TM1187A Issue CPage 2 - 8

Loud Speech (Simplex)

23. Under some circumstances telephone-style communication will not be possible, e.g.
noisy environment, wearing of protective headgear, etc. The high volume levels
required for listening would inhi bi t operation because of feedback. In this situation a
PMR-style of operation is desirable.

24. T o se lect loud speech, press twice (the message "Use PTT" is displayed). To
speak, depress the PTT key. Release the PTT switch after speaking, to listen to the
oth er party. Subsequent presses of toggles the transceiver between telephone
mode (the m essage "On" is displayed) and loud speech mode (message "Use PTT" is
displayed).

New Status

25. Each call is automatically given new status when first received. New status is removed
by cancelling the alert or reviewing the call from memory. If the alert is left uncancelled
then the prompt "x new messages" appears on the display showing the number of
messages with new status (where x is a integer from 1 to 5). Each message must be
viewed in full for new status to be removed.

Cancelling Alerts

26. Ca nce l t he alert by pressing the button. The beep and LED alert cease but the
message is replayed from the beginning.

Escalating Alert

27. The escalating alert has three stages - the first two lasting 4 seconds each and the last
one 8s, 16s, 32s or continuous. The stages are as follows:

Stage 1: LED, flashing beep pattern.
Stage 2: LED, low volume beep pattern.
Stage 3: LED, full volume beep pattern.

28. The option for Escalating Alert is programmed into the EEPROM. However, the
escalating alert and the Mute mode are overridden by beep code 5 (triple pip) and beep
code 8 (continuous pip). They cause the alert to be on full volume for the whole of the
programmed alert duration.

BEEP CODE

RPR 563GS/KGS

TM1187A Issue C Page 2 - 9

Table 2: Beep Code and Alert Patterns

* The escalating alert and the Mute mode are overridden by beep code 5

(triple pi p) and beep code 8 (continuous pip). They cause the alert to be on
full volume for the whole of the programmed alert time, or for four seconds
if it is a speech call.

NOTE: Silent Alert is not currently supported by Access 3000 systems.

Extended Alert

29. If enabled and the c all is not cancelled, the transceiver enters extended alert after the

normal alert has finished. During extended alert, the LED flashes for 0.125s, every 2s.
Two 0.125s pips (2s apart) are emitted every two minutes (unless in Mute mode). The
pips are synchronised to the LED flashes.

RPR 563GS/KGS

TM1187A Issue CPage 2 - 10

Memory Replay

30. Incoming messages are automatically entered into the transceiver's mem ory store which
can accomm odate up to five calls. To start the memory replay cycle, from the quiescent
dis play, press the button twice. If in extended alert, press the key once only.
The transceiver displays the header of the first message (or the phrase "no messages"
if none exist). If no messages exist, the display returns to quiescent mode after
2 seconds.

31. Ne w messages which have not been cancelled are displayed first. W hen all new
messages have been reviewed, the tra nsceiver returns to qui escent mode. Once new
status has been removed it is possible to view all the messages in the memory by
pressing again.

32. The header refers to the fi rst message screen and consists of a time stamp, plus the
initial part of the message (or the whole message if 14 characters or less). Press

to step through each message header on the display. The most recent call is displayed
first and corresponds to the `1'.

33. The display automatically scrolls through messages at 1.25 second intervals until the
final screen is reached. The final screen terminates in ** (to denote the end of the
message) and is displayed for 2.5 seconds. If all messages have been viewed the
transceiver display returns to the quiescent condition.

Making a Call (Telephone-Style Operation)

34. The procedure for making a telephone-style call is as follows:
a) Press . The message "Please Wait" will be displayed. If the channel is clear

(base station not transmitting sub-audio tone) then the transcei ver sends its Talk
code in DTMF. The transceiver then reverts to its quiescent state.

b) W hen the system is ready to service the call it sends a "Line Ready" call. The

transceiver rings, displays the message "Ready" and drops into telephone mode,
i.e. the transceiver audio volume will be adjusted to telephone speech level. Dial
tones from the system will normally be heard on the RPR 563KGS version.

c) Enter the required di a lling sequence.

35. If, after a predetermined interval, the system does not respond with a "Line Ready" call,
the transceiver sends its Talk code again, and repeats thi s process at the specified
interval until a response is received from the system. If the key has been pressed
and a Line Ready call is subsequently received, the transceiver still sends the Un-Talk
code and reverts to its quiescent state.

36. The line request can be cancelled at any time by pressing .

RPR 563GS/KGS

TM1187A Issue C Page 2 - 11

37. On RPR 563GS (reduced keypad version), connection to the designated point is

automatic once has been pressed.

Making a Call to a Telephone (RPR 563KGS only)

38. Once the dial li ng tone has been recei ved, the telephone number may be dialled as if

calling from another telephone.

Making a Call to Another Mobile (RPR 563KGS only)

39. The procedure for making a call to another mobile is as detailed in paragraph 34. If the

call is to another receiver, then the user number and numeric message must be dialled
when requested by the system.

40. A control message is sent by the system which sets the transceiver into simplex mode.

If s u b - a u di o tone from the system is lost before the control message is received, the
transceiver displays the message "Please Wait". When the sub-audio tone re-appears,
the message "Use PTT" is displayed.

41. If the recipient has a non-speech receiver then the system clears down the originator

when the message has been sent.

Making a Call to a Manual Control Unit (RPR 563KGS only)

42. Once the "Line Ready" call has been received, connection is made using designated

MCU intercepts. The default intercept numbers are:
*0 to call several MCUs which have continuous talkback monitoring facilities

or:

*1 to *8 to call a designated MCU.

Terminating a Call

43. To terminate a call, press . The transceiver sends i ts Un-Talk code, displays the

message "Call ended" and reverts to quiescent state.

44. An internal speech timeout function will terminate a speech call if it has not been

terminated manually. The system may also terminate the call but will warn the user with
a tone a few seconds before termination.

RPR 563GS/KGS

TM1187A Issue CPage 2 - 12

45. If a team call is transmitted, or another user makes an emergency "Burst-In" call, the
system w ill override and terminate the call without prior warning. The transceiver that
has been overridden will display the message "Call Override".

46. If the battery pack voltage becomes too low during a transmission, the transceiver
sends the un-talk code at low volume and then keys down. A `low-battery' buzz is then
generated if the option is enabled.

Program Volume Modes

47. Pr ess in g f oll owed by [1], followed by a DTMF key between 1 and 5 initiates the
setting for one of five transceiver volume modes, as follows:

Key Sequence Function Displayed Message

[1] [1] Beep Tone Volume Volume 1:
[1] [2] Ring Volume Volume 2:
[1] [3] Simplex Speech Volume Volume 3:
[1] [4] Telephone Speech Volume Volume 4:
[1] [5] DTMF Volume Volume DTMF:

48. To reduce the volume level for the selected mode, press [ ] repeatedly until the correct

*

lev e l i s attai ned. To increase the vol ume level, press [#] repeatedl y until the correct
level is attained. To store the new setting, press [1]. The new setting is also stored if
no key presses are made for at least six seconds. On leaving this mode, the message
"Volume Set" is displayed.

ABSENCE RACK REGISTRATION AND CHARGING

49. T he tra nsceiver contains a rack message which may be up to a maximum of nine
characters in length. The factory programmed default rack message "Absent" may be
changed by using Programm ing Unit P648 and programming software P648T, together
with an IBM PC or compatible personal computer.

50. Insert the transceiver into a pocket within the rack. The transceiver's LED illuminates
at half brightness when charging commences and the following rack message appears
on the display when the transceiver recognises absence mode.

Absent or PROGRAMMED MESSAGE

51. The transceiver is interrogated by the system and if a user number is associated with
the transceiver address the user number is displayed as follows:

Absent 1234 or PROGRAMMED MESSAGE 1234

RPR 563GS/KGS

TM1187A Issue C Page 2 - 13

52. If the interrogation is unsuccessful there are two possibilities:

a) If there is no contact between system and transceiver, the following display is

shown:

Absent or PROGRAMMED MESSAGE

b) If there is no user number associated with the transceiver address the foll owing

display is shown:

Absent ---- or PROGRAMMED MESSAGE ----

53. If the transceiver is switched off when inserted into the rack with a serviceable battery

unit, t h e c h a rg e la mp will light b u t no absence registration will take place. If the battery
uni t i s fl at when i nserted in the rack, the transceiver will switch on, the charge lamp
illuminates and registers absent as normal.

54. If the transceiver is placed in the absence rack with a totally-discharged battery pack,

one of the following situations will arise:
a) the charge LED will light, the absent or programmed message will be displayed.

b) the charge LED will light, flashing `E's will be displayed.
c) the charge LED will light, the transceiver will switch on and start its initialisation

routine.

RECHARGING THE BATTERY PACK

55. If the battery pack voltage becomes too low during a transmission, the transceiver

sends the un-talk code at low volume and then keys down. A `low-battery' buzz is then
generated if the option is enabled.

56. A discharged battery pack may be trickle-charged by inserti ng it into the pocket of a

P622 or P623 Trickle Charging Unit. Alternatively, the battery pack may be fast­charged by inserting i t into the pocket of a P616 or P619 Personal Charging Station.
Discharged battery packs may be re-charged with or without the transceiver attached.

57. Brand new battery packs normally require a few charge and discharge cycl es before

they settle into their normal charging behaviour. New uncharged battery packs should
be charged three or four times before initial use. This is achieved by taking the charged
battery p a ck/t r a n s c e i v e r o u t o f t he cha r g i n g s tation and, once the LED charge indicator
is extinguished, inserting it again.

CIRCUIT SUMMARY

1. T he t ra nsceiver comprises two printed circuit boards, the Radio Board and Decoder
Board, which are connected directly to each other via a 14-way plug and socket. The
Radio Board carries all the components for the transmitter and receiver with the
exception of the microphone and loudspeaker circuits. Separate antennae are used for
receive and transmit.

2. T he receiver is of double superheterodyne desi gn with intermediate frequencies of

21.4MHz and 455kHz. The RF, IF and dem odulation circuits are accommodated on the
Radio Board while the audio amplifier and control circuits are located on the Decoder
Board.

3. Frequency modulation is employed in the transmitter. Sub-audio tone and DTMF
signalling is available in addition to speech. A choice of telescopic or flexible antenna
is available for the transmitter. The telescopic antenna may be retracted into the
transceiver and still work but with reduced range.

4. All decode and transceiver control circuits are accommodated on the Decoder Board.
The LCD is mounted on a sm all PCB which is connected to the Decoder Board via two
flexible connectors. A moulding inside the case front assembly holds the LCD at an
angle of 45( to the Decoder Board.

5. Connections to the battery pack are made via eight spring fingers mounted on the edge
of the Decoder Board. These make contact with metal strips on a small PCB fixed to
the base of the case front. Contact is made with the battery pack when it is securely
located on the transceiver body. In addi tion to the battery supply/charging circuits,
there are connections for microphone audio and transceiver programming data lines.

6. A 600mAH or 1200mAH Metal-hydride plug-in battery pack may be fitted to the
tran sceiv e r . Both sizes o f b a t tery p a ck have a no minal voltage of 3.6V and may be fast
or tr ic kle-charged. Each battery pack has a buil t-in microphone unit. Battery packs
may be charged with or without the transceiver attached.

RADIO BOARD

Power Supplies

7. Battery Voltage (B+), TxB+, SPEECH3V and the +4.5V supply lines are derived from

the Decoder Board and are available at PL301.

8. Receiver IF Amplifier IC302 is gated on and off by the Battery Economy Circuit (BEC)

line from the Gate Array on the Decoder Board (via PL301 pin 12). This can be
overridden for manual tests by taking /BEC.EN low. When gated on, TR322 conducts
providing power to pin 20 of IC302, which drives an internal voltage regulator. This in
turn is applied to TR323 to provide a 1V regulated supply rail which powers most of the
receiver. Voltage adjustment is made via RV301.

9. The transmitter oscillator and exciter circuits are powered from an on-board 2.5V

regulator (TxREG) com prising IC301, TR309, TR310 and TR311, and which is powered
from the B+ line. IC301 also supplies a steady bias voltage via R318 to varicap diode
D301.

Receiver

10. A block diagram of the receiver is shown in Figure 1.

11. Receiver antenna AE302/303 is tuned by C339 and C395. Signals from the antenna

are fed to the RF amplifier TR316, TR317. The collector-tuned circuit is used to match
the wideband Surface Acoustic Wave (SAW) filter FL303. Transistor TR315 buffers the
SAW output to the mixer TR318, preventing the SAW filter output affecting the injection
level.

12. The local oscillator comprises TR312, XL303 and associated components. Frequency

adjustment is by C394. Local oscillator frequency is calculated as follows:

fx =

carrier frequency + 21.4MHz

9

where fx is the crystal frequency in MHz.

13. The collector of TR312 is tuned to the third harmonic of XL303 by C382. TR312 output

is then tripled by TR337 to provide the correct i njection frequency for the mixer. The

21.4MHz IF signal is passed by filter FL302, providing further selectivity.

14. The second oscillator runs a t 2 0 .945M H z and consists of TR314, XL302 and associated

components. Output from the oscillator is loosely coupled to the second mixer TR313,
wher e it mixes with FL302 output to form the 2nd IF of 455kHz. Resistor R352 on
TR312 collector provides matching for the 455kHz ceramic filter FL304.

Page 3 - 5

15. Ou tp ut from FL304 is amplified by the first amplifier in IC302 before applicati on to a

second 455kHz filter FL305. The signal is then fed back into IC302 for further
amplification and application to the internal quadrature discriminator.

16. A 90( phase shift to the discriminator's second input is provided by L302 and the

demodulated audio is then output at pin 14 where it is split three ways thus:
a) Received audio (RXAUDIO)

b) Sub-Audio Tone decode (TONEX)
c) Data Filter

17. The received audio is fed through de-emphasis network R359, C405, and then to the

high-pass filter TR321. This stage removes low frequency noise from the signal. From
thi s po int the audio signal is fed to the Decoder Board for further amplification and
processing.

Data Filter

18. The data signal passes through a separate de-emphasis network (R360/C404).

Tra ns istor TR353 is an anal ogue switch which is controlled by the Battery Economy
Circuit (BEC). The data signal is then fed to IC302 pin 15 where it is squared up and
output at pin 16. This open collector output is then fed to the Decoder Board.

Tone Squelch Decoder/Encoder

19. Sub-audio tones are applied to the de-emphasis network R370, C 414 before application

to two-pole fi lter stage TR328/TR329, which has a break frequency of approximately
170Hz. Output is fed to a second two-pole filter, TR331/TR332, thus reducing the
amount of speech content in the signal presented to the Phase Locked Loop (PLL)
IC303, enhancing the tone squelch performance.

20. After filtering, the tone signal is then amplified by IC305. Potential divider R382/383 is

used to set the input amplitude of the signal to IC303 pin 3. When a si gnal of the
cor re ct fr eq uency is detected, IC303 pi n 8 is pull ed low; this is the TONE.RX signal
which is supplied to test socket PL302 and to the Decoder Board.

21. The oscillat or f o r t h e P L L (I C 303) runs at twice the tone frequency and is set by RV302.

Tone output from IC303 at pin 5 is fed to Flip-Flop IC304 which divides the tone
frequency by 2. Filtering is provided by two low-pass filter stages TR336 and TR349.
Output is applied to PL302 pin 9 for test purposes, and via potential divider R444/R435
to the modulator driver IC306.

Transmitter

22. A block diagram of the transmitter is shown in Figure 2.

23. Amplified microphone speech is applied to PL301 pin 8 and is clamped by
TR348/TR347 before appl icati on to the two low-pass filters formed by TR345/TR346
and TR350/TR351. The filters limit the audio bandwidth to 3kHz. After filtering the
signal is applied via R443 to IC306a.

RPR 563GS/KGS

TM1187A Issue C

Page 3 - 7

24. The sub-audio tone derived from IC303 and IC304 (see paragraph 21) is applied to

IC306 via potential divider R435/R444. When DTMF tones are generated by the
Decoder Board, they are applied to IC306a via R419, R420 and R445. The tones are
als o appl ied to IC306b for amplification, rectifi ed by D303 and C451, and applied to
TR341, which mutes the speech circuits from the microphone. This allows DTMF tones
to be transmitted without speech superimposed.

25. IC 306 acts as an amplifier and combiner for the speech, sub-audio tone and DTMF

signals to be transmitted. Modulation is taken from RV303 wiper and applied to the
transmitter modulator.

26. The transmitter oscillator is formed by TR301 using a series resonant crystal XL301.

Frequency adjustm ent is provided by C349. Audio for transmission is applied to varicap
diode D301 which modulates the crystal oscillator frequency. XL301 frequency is
determined by the following formula:

fx =

carrier frequency (MHz)

18

where fx is the crystal frequency in MHz.

27. The second harmonic is selected at TR301 collector via C350 and is tripled by multiplier

TR302. The output of thi s stage has a low `Q' un-tuned output and is coupled to
another tripler TR303 which boosts the level to 0dBm. This signal is applied to SAW
filter FL301 to remove unwanted com ponents before further amplification by TR305 and
TR307. Bias for TR305 is provided by TXDEL and TR304. Interstage matching is
carried out by balun type matching transformers.

28. Po wer output from the PA is approximately 50mW. Harmonics are removed by low-

pass filter L320, C347, and C348. Inductor L322 maintains adequate matching for the
telescopic antenna even when stowed.

29. At the end of each transmission the Decoder takes the /TxKEY line high.

DECODER BOARD

Power Supplies

30. Battery voltage (B+) is suppli ed from the battery pack at PL101 pin 3 and is split into
two supplies, B+ and TxB+. TxB+ powers the Radio Board tra nsmitter power amplifier
only, via SK101 pin 13. B+ is used on bo th the Radio and Decoder Boards, the Radio
Board connection being at SK101 pin 7. Protection against reverse-polarity connection
is afforded by a surface-mounted fuse FS102 and diodes D118, D119.

31. T he 4.5V voltage converter comprises PNP transistor TR105, T101 and associated
components as an oscillat o r running at between 20kHz and 100kHz. Converter output
is rectified and smoothed by D104 and C121. The output level is fed back to current
mirror control loop TR101-TR104 to bias the base of the oscillator. A constant 4.5V
is thus maintained with accuracy and temperature performance defined predominately
by the ratios of R105, R111 and R106.

32. When the Speech Enable line /SP.EN on IC101 goes low, TR122 is turned on,
supplying battery voltage (SPEECH3 V) to th e microphone and l oudspeaker amplifier
ci rcu it s. The SPEECH3V li ne is al so made available to the Radio Board at SK101
pin 9.

33. A `Low Battery' indication is provided by IC103. When B+ drops to  3V, the output of
IC103 applies a `low' to microprocessor IC101 at pin 44. If the BACKUPB+ line drops
below 2.2V, IC104 signals a reset to the Gate Array at pin 5.

RPR 563GS/KGS

Receiver Audio Stages

34. Re ceiver audio (RXAUDIO) from the Radio Board is applied to SK101 pin 3 and fed

through the squelch gate transistor TR119 which is controlled by the decoder squelch
output. If valid audio is received then the transistor conducts and the signal is passed
to pin 7 of pre-amplifier IC106. Output from IC106 pin 1 is passed to D106, TR124 and
TR117 which form an AGC circuit, and to IC107 which amplifies the signal to dri ve
loudspeaker LS101. Amplifiers IC106 and IC107 operate only when SPEECH3V is
present.

35. Control of loudspeaker volume is achieved by an electronically-controlled potentiometer

comprising R171, and transistor-switched resistors R135, R137, R139 and R141.
Transistors TR111-TR114 which provide the potentiometer switching, are controlled by
microprocessor IC101.

Microphone Audio Stages

36. Audio from the microphone is fed via C137 to IC106 at pin 6. It is then amplified and

fast AGC-limited by IC106, D105, TR120 and TR121 to give a maximum level of 1.2V
peak-to-peak. Microphone audio is then output at SK101 pin 8 to the Radio Board.

Decoder

37. T he decoder circuits comprise Gate Array IC105, microprocessor IC101, EEPROM

IC102 and associated components.

38. Microprocessor IC101 carries out the decoding and control functions of the transceiver.

Its functions include:
a) DTMF tone generation from a built-in encoder. Output is presented at pin 47.
b) Scans the keypad to determine which key has been pressed.
c) Drives the display module.
d) Switches the LCD and keypad backlighting on and off.
e) Controls the /TxKEY and /SQUELCH lines.

39. The LCD module is controlled directl y from IC101. The icon is driven from IC101 via

TR115, C119 and C118. Power to the display is provided via TR108 which is gated by
IC101. Backlighting for the display and keypad is controlled by TR107 gated by IC101.

40. The clock oscillator is provided by crystal XL102 and internal components running at

3.58 9MHz. Receiver address and transceiver options are programmed in EEPROM
IC102, which are read serially by the microprocessor at switch-on. IC102 is
programmed by the microprocessor with data which is supplied from the programming
unit P648 via the Absence Rack Data (ARDATA) contacts on the battery pack.

Gate Array (IC105)

41. Gate Array IC105 is responsible for the following functions:

a) De tects operation of the Cancel button and passes the data to microprocessor

IC101.
b) Resets IC101 under various conditi ons.
c) Pre-conditions incoming data (detects preamble, etc.).
d) Controls the Battery Economy Circuit (BEC) line.
e) Generates the beep drive waveform.
f) Drives the Alert LED D101 (D101 is also driven at reduced brightness via TR116

when the unit is on charge).

42. T h e c lock f or the Gate Array is provi ded by the external oscillator formed by TR131,
XL101 and associated components.

43. The receiver circuits are powered up for a brief interval once a second by BEC, so that
IC105 can check for the presence of Mk7 preamble (256Hz square wave). If preamble
is detected, the receiver remains powered up while IC105 acquires batch
synchronisation. When synchronisation has been achieved, IC105 generates interrupts
from its DTI output (pin 66) which are applied to the microprocessor INT4 input (pin 1)
ever y 62 .5ms (32 bit periods). After each interrupt the microprocessor collects the
32 data bits in nibbles (4-bit words) using the parallel data bus DA0-DA3.

BATTERY PACK

44. Contacts for charging and transceiver programming are provided on the battery pack.
The contacts used for programming may also be used for absence registration on
Multitone systems that provide that facility.

45. A thermistor is provided in the high capacity battery pack to allow fast charging circuits
to sense battery temperature as a part of their control loop. Trickle-charging from 12V
is possible via a small DC socket on the side of the battery pack using Multitone
Charger 6603-0001.

46. A microphone is included in the battery pack.

DISASSEMBLY

Belt Clip Assembly

7. Re f e r r i ng to Figure 1, apply pressure to the centre of the clip (marked `A') so that its

mounting spring sits proud of its recess, then use a 4mm wide blade (at position `B') to
prise the spring away from the case.

8. To refit the clip, locate the lower end of the clip spring into the corresponding cut-out in

the case , then apply pressure to the centre of the clip, forcing the other end of the
spring into its corresponding recess.

Removing the Antenna

9. One of two antennas may be fitted. If the antenna is of the telescopic type, fully retract

it prior to removal. To remove the antenna, unscrew it (anti-clockwise) from the case
using a 9mm A/F spanner. Note that early telescopic versions have a knurled base.

Decasing the Transceiver

10. To decase the transceiver, refer to Figure 2 and carry out the following procedure:

a) Remo v e t h e antenna as detailed in paragraph 9. Note that failure to remove the

antenna prior to disassembly may result in damage to the PCB assembly or
antenna.

b) Remo v e the ba t t e r y p a ck by p r e s sing t h e b a ttery r e lease button inwards and sliding

the battery pack away from the transceiver.

c) With the transceiver held face downwards, squeeze the sides of the case at point

`C'. At the same time hook the first and second fingers of the other hand round the
lip at the end of the case back, and then peel back. The case back will unclip itself
from that end.

d) Now squeeze the case sides with thumb and fore finger at points `D'. If the case

back does not come free, squeeze the case at either side of the speaker aperture:
the case back will now hinge clear.

e) Undo the two screws securing the Radio Board and gently prise the board out from

the battery end with a blunt instrument.

f) Undo the six screws securing the Decoder Board to the case front. Take care not

to damage the loudspeaker wires when lifting the Decoder Board away. Note that
on early models the two screws nearest the Display Module are longer.

g) To remove the Decoder Board completely, release the loudspeaker from its retainer

by undoing one or more of the screws securing the retainer to the case front. Lift
out the Decoder Board with the loudspeaker.

h) If required, the Display module may be disconnected by unsoldering its ribbon cable

from the Decoder Board. Likewise the loudspeaker may be disconnected by
unsoldering its wires from the Decoder Board.

Removing the Display Module

11. The procedure for removing the Display Module is as follows:
a) Unclip the Interface moulding from the Display Module.
b) Remove the two screws securing the moulding to the Decoder PCB. Remove the

moulding.

c) Unsolder the flexible interconnects from the Decoder PCB.

Re-Assembly

12. Re-assembly is a reversal of the above procedure. To re-case the transceiver, insert
the antenna end of the case back at an angle of 45( into the corresponding end of the
case front. Ensure that the antenna end of the case back fits snugly into the case front.
Lower the case back into position and snap the two halves together.

FAULT FINDING

General

13. Connections to the transceiver can be made via the test socket SK301. Refer to Figure
4 for connection details.

14. The location of test points can be found in Figure 5.

RPR 563GS/KGS

TM1187A Issue C

Page 5 - 9

Power Supply Voltage Adjustment

15. Adjustment of the power supply is limited to the 1V rail. The procedure is as follows:

a) Remove the case back.
b) Fit a fully-charged battery pack and switch on.
c) Connect a link between SK301 pins 3 and 10 to disable the battery economy circuit.
d) Connect a multimeter to TP303. Adjust RV1 to give a meter reading of 1.07V

(±0.01V).

`Low Battery' Circuit Test

16. The `Low Battery' option must be enabled in the EEPROM if operation of this circuit is

to be checked. The procedure for checking operation is as follows:
a) Remove the case back and Radio Board. Connect the Radio Board to the Decoder

Board using the interconnect lead.

b) Connect a variable DC supply to the Decoder Board via the red and brown wires on

the interconnector. Set the power supply voltage to 2.6V DC.

c) Switch on. The transceiver should initiate its switch-on procedure. A `Low Battery'

warning buzz should sound instead of a beep, as follows:
i) Quiet Tone (modulated by `Low Battery' buzz).

ii) Alert Lamp.
iii) Show all LCD segments.
iv) Display Receiver Address.
v) Display Switch-on Message.
vi) Display message `BAT'.

d) Press the Memory Recall button and check that the message `Low Battery' is

displayed. If the transceiver is called, the beep pattern changes to a buzz.
e) Switch off the transceiver. Increase the power supply output to 3.2V DC.
f) Switch on the transceiver and check that the normal switch-on sequence occurs.

ALIGNMENT PROCEDURE

Preliminaries

18. Prior to alignment, remove the antenna and case back. Fit a fully-charged battery pack,
and place the transceiver into the P654 Alignment Jig, and connect the audio connector
lead to SK301. Refer to Section 5, Annexe C, for P654 details.

Receiver Alignment

19. The Receiver alignment procedure is as follows:
a) Connect the test equipment to the P654 as shown in Figure 14.

b)
Enable receiver speech on the Radio Board by initiating Test Mode 3.

c) Usin g a x10 oscilloscope probe, connect the SINAD/AC Millivoltmeter to SK301

pin 12, and set to AC mV.

d) Check that the Receiver 1V line voltage at SK301 pin 11 is at 1.07V ±0.01V (using

a Digital Multimeter). Adjust RV301 as necessary.

e) Tune the RF signal generator to 10.7MHz with 1kHz modulation, deviation set to

±3kHz. Set the level to -20dBm and connect to the P654 BNC socket.

f) Adjust L302 for maximum level.
g) Set the oscilloscope to DC input. Adjust the vertical position so that the sine wave

is in the centre of the display.

h) Retune the RF signal generator to the receiver channel frequency. Adjust C394 for

the same DC level on the oscilloscope as achieved in step g). Whilst adjusting the
signal generator output to maintain 12dB SINAD, adjust the trimmers in the following
ord er:- C399, C441, C412, C379, C382. Some interaction may occur between
trimmers, therefore, the tuning sequence may need repeating to optimise

A level better than -95dBm should be achieved.

Transmitter Alignment

20. The transmitter alignment procedure is as follows:
a) Connect the test equipment to the P654 as shown in Figure 16.

b) Set the transceiver into permanent transmit by initiating Engineering Test Mode 4,

or by connecting SK301, pin 1 to pin 10 (Tx Key to 0V).

c) Remove the copper tape covering the screening can alignment holes.
d) Adjust C349 to the transmitter channel carrier frequency ±0.5kHz.
e) Adjust C350 to fine the transmitter frequency.
f) Carry out steps d) and e) until there is no interaction between adjustments.
g) Tune C353 and C354 in turn for maximum output power (20-50mW). Repeat until

there is no interaction between adjustments.

h) Check that the carrier frequency remains within ±0.5kHz of the transmitter channel

centre.

Deviation Level

21. The transmitter deviation level is set as follows:

a) Connect the test equipment to the P654 as shown in Figure 17.

b)
Make the following connections to SK301 (Test Socket):

i) Pin 6 to AF signal generator.
ii) Pin 4 to Pin 9 (SPEECH3V to B+)
iii) Pin 1 to Pin 10 (TxKEY to 0V)

c) S et the AF signal generator to 1kHz at 1V peak-to-peak. Adjust RV303 to give

±3.6kHz deviation.

Receiver Sensitivity Check

23. To determine receiver sensitivity, carry out the following procedure:

a) Connect the test equipment to the P654 as shown in Figure 19.

NOTES:

1. The distance between the personal computer and the P654 must not be less
than 2 metres.

2. Test results are dependent on a noise-free environment.

b) Tune the RF signal generator to the receiver channel frequency and adjust the

deviation level to ±4.5kHz. Adjust the carrier level to -85dBm.

c) S end test calls from the P645, increasing the RF signal generator output level, if

necessary, to obtain correctly received calls.

d) Reduce the RF carrier level in 1dB steps until the transceiver receives two calls (or

less) in five.

e) Increase the RF carrier level in 1dB steps until five consecutive calls are received.

An output level of -90dBm or better should be achieved.

PROGRAMMING THE TRANSCEIVER

24. The transceiver contains an EEPROM which holds unique data, including its receiver
address. This data may be entered or changed by using the P648 Programming Unit
and the P648T Programming Software. P648 operation is detailed in Section 5,
Annexe B.
