))))))))))))))))

ROLE

1. The Multitone RPR 563K radio paging transceiver comprises a UHF receiver and VHF transmitter, allowing paging and two-way speech facilities. The unit can receive alphanumeric paging messages and make paging, speech and telephone calls. The transceiver may be used in simplex or duplex (telephone) mode.

2. Paging and telephone calls are made via a DTMF keypad. A reduced keypad version of the transceiver, designated the RPR563 (which does not have a DTMF keypad) is available which is able to make limited telephone calls.

3. A choice of plug-in metal hydride battery packs are available to power the transceiver. All battery packs 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 paging systems.

4. Paging 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 transceiver 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.

RPR 563

TM1195 Issue 1 Page 1 - 3

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 paging call. Speech calls are indicated by ringing patterns which match the appropriate tone alert codes.

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.

RPR 563

TM1195 Issue 1Page 1 - 4

Display Direction Control

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

Engineering Mode

14. May be used for reviewing programmed options in the transceiver. This feature is useful for when carrying out engineering work on the paging system.

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 pager to be operated 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.

RPR 563

TM1195 Issue 1 Page 1 - 5

Call Comparator

20. Prevents the transceiver from reacting to an identical message received within a pre-

determined 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 paging call.

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 563K transceivers, the volume levels for beep tone, ring tone, telephone

speech, pager 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.

RPR 563

TM1195 Issue 1Page 1 - 6

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 paging format may be set to 0, 1, 2, or 3. The default system number is 1.

System Retry Interval

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

Switch-On and Rack Message

31. 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".

Table 1: Message Display Formats

11. The displayed message comprises combinations of the following elements:

Element Example

a) Time stamp + space 12:00 b) Beep Code (Tone Only message) 4 c) Speech call Speech 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 alert, if uncancelled. On cancelling 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 cancelling the alert the message is displayed again from the beginning.

RPR 563

TM1195 Issue 1Page 2 - 8

16. The transceiver is able to receive new calls during an alert, although 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 Paging Speech Call

17. When a call is received, the Alert LED will flash and a telephone-style ringing tone will be audible for four seconds. Any alphanumeric message will be displayed as for a nonspeech call. The speech audio channel switches on immediately after the audible 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 paging 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 will drop to the programmed telephone speech level. The display direction 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 termination signal from the paging system. The transceiver will display the message "Call Ended".

TM1195 Issue 1 Page 2 - 9

Loud Speech (Simplex)

23. Under some circumstances telephone-style communication will not be possible,

e.g. noisy environment, wearing of protective headgear. The high volume levels required for listening would inhibit operation because of feedback. In this situation a PMR-style of operation is desirable.

24. To select 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 other party. Subsequent presses of toggles the transceiver between telephone mode (the message "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. Cancel the 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.

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

Extended Alert

29. If enabled and the call 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 563

TM1195 Issue 1 Page 2 - 11

Memory Replay

30. Incoming messages are automatically entered into the transceiver's memory store which

can accommodate up to five calls. To start the memory replay cycle, from the quiescent display, 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. New messages which have not been cancelled are displayed first. When all new

messages have been reviewed, the transceiver returns to quiescent 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 first 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

(i.e. the base station is not transmitting) then the transceiver sends its Talk code in DTMF. The transceiver then reverts to its quiescent state.

b) When the paging 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 paging system will normally be heard from the transceiver.

c) Enter the required dialling sequence.

35. If, after a predetermined interval, the paging system does not respond with a "Line

Ready" call, the transceiver sends its Talk code again, and repeats this process at the specified interval until a response is received from the paging 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 563

TM1195 Issue 1Page 2 - 12

37. On reduced keypad versions, connection to the designated point is automatic once has been pressed.

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

38. Once the dialling tone has been received, the telephone number may be dialled as if calling from another telephone.

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

39. The procedure for making a call to another mobile is as detailed in paragraph 34. If the call is to another paging receiver, then the user number and numeric message must be dialled when requested by the paging system.

40. A control message is sent by the paging system which sets the transceiver into simplex mode. The message "Use PTT" is displayed by the transceiver.

41. If the recipient is a non-speech paging receiver then the paging system clears down the originator when the message has been sent.

Making a Call to a Manual Control Unit (RPR 563K 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 its 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 paging system may also terminate the call but will warn the user with a tone a few seconds before termination.

RPR 563

TM1195 Issue 1 Page 2 - 13

45. If a team call is transmitted, the paging system will override and terminate the call

without prior warning. The transceiver that has been overridden will display the message "Call Override".

Program Volume Modes

46. Pressing followed 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 Beep Volume [1] [2] Ring Volume Ring Volume [1] [3] Pager Speech Volume Belt Volume [1] [4] Telephone Speech Volume Ear Volume [1] [5] DTMF Volume DTMF Volume

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

level is attained. To increase the volume level, press [#] repeatedly 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.

RECHARGING THE BATTERY PACK

48. 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.

49. A discharged battery pack may be trickle-charged by inserting it into the pocket of a

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

50. Brand new battery packs normally require a few charge cycles 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 pack/transceiver out of the charging station and, once the LED charge indicator is extinguished, inserting it again.

RPR 563

TM1195 Issue 1Page 2 - 14

ABSENCE RACK REGISTRATION AND CHARGING

51. The transceiver 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 Programming Unit P648 and programming software P648T, together with an IBM PC or compatible personal computer.

52. 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

53. 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

54. If the interrogation is unsuccessful there are two possibilities: a) If there is no contact between paging 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 following

display is shown:

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

55. If the transceiver is switched off when inserted into the rack with a serviceable battery unit, the charge lamp will light but no absence registration will take place. If the battery unit is flat when inserted in the rack, the transceiver will switch on, the charge lamp illuminates and registers absent as normal.

56. 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.

CIRCUIT SUMMARY

1. The transceiver 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. The receiver is of double superheterodyne design with intermediate frequencies of 45MHz and 455kHz. The RF, IF and demodulation 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. DTMF signalling is available in addition to speech. A choice of a ferrite stub or flexible whip antenna is available for the transmitter.

4. All decode and transceiver control circuits are accommodated on the Decoder Board. The LCD is mounted on a small 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 45E 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 addition 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 transceiver. Both sizes of battery pack have a nominal voltage of 3.6V and may be fast or trickle-charged. Each battery pack has a built-in microphone unit. Battery packs may be charged with or without the transceiver attached.

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 IC1 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, TR23 conducts providing power to pin 20 of IC1, which drives an internal voltage regulator. This in turn is applied to TR20 to provide a 1V regulated supply rail which powers most of the receiver.

9. The transmitter oscillator and exciter circuits are powered from the TxREG line, an on-

board 2.5V regulated supply derived from IC6, which in turn is powered from the B+ line. The second driver, intermediate power amplifier and power amplifier are powered from the B+ supply which is gated via TR319 and the /TxKEY line.

TM1195 Issue 1 AL2 (April 1999)Page 3 - 4

Receiver

10. A block diagram of the receiver is shown in Figure 2.

11. Receiver antenna AE302/303 is tuned by CV3, C411 and C134. A notch filter set at 160MHz is provided by C117, L102, C118, L101, to suppress carrier from the transmitter section. Signals from the antenna are fed to the RF amplifier TR35, and the resultant output at the collector is fed to helical filter FL7. FL7 provides a degree of selectivity before applying receiver channel signals to the first mixer TR30.

12. The local oscillator comprises TR34, XL10 and associated components. Frequency adjustment is by CV2. Local oscillator frequency is calculated as follows:

Bands Z, Y, X, W: fx =

carrier frequency - 45MHz

Band V only: fx =

carrier frequency + 45MHz

where fx is the crystal frequency in MHz.

13. The collector of TR34 is tuned to the third harmonic of XL10 by CV4 and L6. TR34 output is then tripled by TR33 and fed via helical filter FL8 to provide the correct injection frequency for the mixer TR30. The collector of TR30 is tuned to 45MHz by L4 and C114. The resultant 45MHz IF signal is passed by the crystal filter XL8, providing further selectivity.

14. The second oscillator runs at 44.545MHz and consists of TR31, XL11 and associated components. TR31 collector is tuned by L308 and C93. Output from TR31 emitter is fed to the second mixer TR32, where it mixes with XL8 output to form the 2nd IF of 455kHz. Resistor R360 on TR32 collector provides matching for the 455kHz ceramic filter FL3.

15. Output from FL3 is amplified by TR25 before application to the second 455kHz filter FL4. Output from FL4 is then applied to the first amplifier in IC1 before application to a third 455kHz filter FL2. The signal is then fed back into IC1 for further amplification and application to the internal quadrature discriminator. A 90E phase shift to the discriminator's second input is provided by ceramic discriminator FL1.

16. Demodulated audio is then output at pin 14 where it is split three ways thus: a) Received audio (RXAUDIO) b) Noise Squelch c) Data Filter

17. The received audio is fed through de-emphasis network R339, C83, and then to the high-pass filter TR29. This stage removes low frequency noise from the signal. From this point the audio signal is fed to the Decoder Board for further amplification and processing.

RPR 563

TM1195 Issue 1 Page 3 - 5

Figure 2: Radio Board - Receiver Block Diagram

RPR 563

TM1195 Issue 1Page 3 - 6

Data Filter

18. The data signal passes through low-pass filter Transistor TR24 which is controlled by the Battery Economy Circuit (BEC). The data signal is then fed to IC1 pin 15 where it is squared up and output at pin 16. This open collector output is then fed via TR26 to the Decoder Board. Data polarity can be changed by fitting R350 or R351; the default polarity is with R350 fitted.

Noise Squelch

19. Demodulated audio is applied to the de-emphasis network R365, C154 before application to high-pass filters TR53 and TR41. TR41 emitter output is then applied to amplifier chain TR40, TR39, TR38, TR42 and TR43. Temperature stability is provided by TR42. The signal at TR43 collector is passed via C166 where it is DC-shifted by D3 and then rectified by TR37, TR28, before application to Schmitt Trigger TR45, TR46, TR36, TR47.

20. Transistor TR46 base is sitting at approximately half-rail voltage. When there is no carrier present (i.e. high noise level) TR45 base will be high, switching TR36 on. The base of TR47 will be low, switching TR47 on, thus holding TR45 base high.

21. When carrier is present (i.e. no noise) TR45 base will be lower than TR46 base, pulling TR36 base low. TR36 will switch on, pulling TR47 base high, switching TR47 off, thus holding TR45 low.

22. The output of the Schmitt Trigger is at the collector of TR36. When TR36 is switched on (no carrier present), TR48 is switched on via R419, thus charging C85, switching TR49 on, and TR50 off. When TR36 is switched off (carrier present), TR48 is switched off, causing C85 to discharge. The discharge time is approximately 100ms and is determined by C85 and R420. Transistor TR49 is switched off once C85 has discharged, thus switching TR50 on.

23. The collector of TR50 collector (/TONE.Rx) is connected to the Decoder Board via PL301 pin 2.

Sub-Audio Tone Generator

24. The oscillator for the PLL (IC2) runs at the tone output frequency and is set by RV3. Tone output from IC2 is at pin 5. Filtering is provided by two low-pass filter stages TR51 and TR52. Output is applied to SK301 pin 9 for test purposes, and via potential divider R65/R64 to the modulator driver IC5.

Transmitter

25. A block diagram of the transmitter is shown in Figure 3.

26. Amplified microphone speech from PL301 pin 8 is clamped by TR15/TR16 before

application to the two low-pass filters formed by TR17/TR18 and TR21/TR22. The filters limit the audio bandwidth to 3kHz. After filtering the signal is applied via R52 to IC5a.

27. The sub-audio tone derived from IC2 (see paragraph 24) is applied to IC5b via potential

divider R65/R64. When DTMF tones are generated by the Decoder Board, they are applied to IC5a via R37, R38 and R60. The tones are also applied to IC5b for amplification, rectified by D1 and C42, and applied to TR14, which mutes the speech circuits from the microphone. This allows DTMF tones to be transmitted without speech superimposed.

RPR 563

TM1195 Issue 1 AL2 (April 1999)Page 3 - 8

28. IC5 acts as an amplifier and combiner for the speech, sub-audio tone and DTMF signals to be transmitted. Modulation is taken from RV301 wiper and applied to the transmitter modulator.

29. The transmitter oscillator is formed by TR301 using a series resonant crystal XL301. Frequency adjustment is provided by RV302. 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)

where fx is the crystal frequency in MHz.

30. The third harmonic is selected at TR301 collector via L301, C329 and C306. L303, C331, C308 and C310 provide further filtering and matching down to 50S output impedance. The output is fed via 3dB pad R320,324,325 to doubler/multiplier TR302. The 3dB pad reduces the interaction between the adjustments of RV302 and CV6. The output of this stage is tuned by L304 and CV6.

31. Output from TR302 collector is passed to TR303 which acts as a buffer/driver for SAW Filter FL301. A 9dB pad comprising R311, R312-313, R336, L331, C355 provides a good broadband match for FL301. FL301 removes unwanted frequency components before passing through matching components L334, C502 and application to transmission line transformer T303. Transformer T303 has a step-down ratio of 4:1, converting a 210S line impedance to a 52S line impedance.

32. To maintain a good broadband match, the signal from T303 passes through 3dB pad R389, R322, R319 before amplification by driver TR327. Transistor TR306 is an intermediate power amplifier, working in Class C, which drives power amplifier TR307 via an 8dB pad formed by R334, R321, R333. As the pad impedance is 50S, R335 may be removed for test purposes.

33. Output power at TR307 collector is approximately 50mW which is applied to transmission line transformer T302 which steps line impedance up from 13S to 50S. Components L346 and C345 provide matching to a five-element low-pass filter which removes unwanted harmonics. Capacitor C346 provides DC blocking.

34. Antenna matching is provided by L322, C140, L321, C139, R337, C187 and L325. Not all of these components are used on all bands, fitment of these components and their values are dependent upon frequency band. For example, resistor R337 provides an output load on bands where no antenna matching is required. Refer to Section 6 for banding information.

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

DECODER BOARD

Power Supplies

36. Battery voltage (B+) is supplied from the battery pack at PL101 pin 3 and is split into

two supplies, B+ and TxB+. TxB+ powers the Radio Board transmitter power amplifier only, via SK101 pin 13. B+ is used on both 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.

37. The 4.5V voltage converter comprises PNP transistor TR105, T101 and associated

components as an oscillator 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.

38. When the Speech Enable line /SP.EN on IC101 goes low, TR122 is turned on,

supplying battery voltage (SPEECH3V) to the microphone and loudspeaker amplifier circuits. The SPEECH3V line is also made available to the Radio Board at SK101 pin 9.

39. 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 563

TM1195 Issue 1Page 3 - 10

Receiver Audio Stages

40. Receiver 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 drive loudspeaker LS101. Amplifiers IC106 and IC107 operate only when SPEECH3V is present.

41. 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

42. 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

43. The decoder circuits comprise Gate Array IC105, microprocessor IC101, EEPROM IC102 and associated components.

44. 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.

45. The LCD module is controlled directly 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.

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

3.589MHz. 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)

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

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

IC101. b) Resets IC101 under various conditions. 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).

RPR 563

TM1195 Issue 1Page 3 - 12

48. The clock for the Gate Array is provided by the external oscillator formed by TR131, XL101 and associated components.

49. 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) every 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

50. 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 paging systems that provide that facility.

51. A thermistor is provided to allow fast charging circuits to sense battery temperature as a part of their control loop. A microphone is included in the battery pack.

Belt Clip Assembly

7. Referring 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. To remove the antenna, unscrew it (anti-clockwise) from the case using a 9mm A/F

spanner. Retain the plastic washer.

Decasing the Transceiver

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

a) Remove the 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) Remove the battery pack by pressing the battery release button inwards and sliding

the battery pack away from the transceiver.

PSG10518-1

RPR 563

Figure 2: Decasing 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) 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.

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 45E 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.

13. Ensure that the plastic washer is located correctly on the antenna prior to re-fitting the antenna.

FAULT FINDING

General

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

RPR 563

TM1195 Issue 1 Page 5 - 9

15. The location of test points are shown in Figure 5.

`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.

ENTERING TEST PROGRAM MODE

1. Four test modes are available via an Engineering Test Program Mode. To enter the

Test Program mode, press , [9], [8], [7], [1] in order.

2. When the Engineering Program Mode has been accessed, the message `Programm'

will be displayed.

3. To exit the Engineering Program Mode, and also cancel test modes and return to

normal operation, press , [1], [0]. Switching off the transceiver also cancels program mode and all tests.

TEST MODE 1

4. Press , [1], [1] to select Test Mode 1. This puts the transceiver into short alert mode,

with escalert and extended alert suspended. If the PTT switch is pressed, the transmitter will key up. The call comparator does not operate in test mode. All other options are unaffected. When called, the transceiver emits a single 1.0s alert tone and the message `TEST' will be displayed for 1.25s. The time stamp (or M number) will also be displayed.

RPR 563

TM1195 Issue 1Page 5A - 2

5. If the call is to the transceiver's individual address, any speech and/or message is ignored and the transceiver will return to battery economy mode. If the call is to the AllCall address, all messages are ignored but the receiver speech circuits will be enabled for 2 to 4 seconds.

6. If the PTT switch is pressed, the transmitter will key up and the message `Test-Mode 1' displayed.

7. Test Mode 1 may also be enabled via the P648 programming unit. In this event the transceiver will record the number of calls it has received and store this in EEPROM when it is switched off or reset. The call counter will store numbers up to 255 (FFh) before resetting to zero. It is possible to interrogate the call counter using the P648T. Select `Edit Transceiver Details' and then select `Hex Display'. The call counter can be found at address 018. Programming `Test Mode' to 0 will reset the call counter to zero.

8. If Test Mode 1 is enabled by the P648T, rather than the transceiver keypad, pressing PTT will not key up the transmitter.

TEST MODE 2

9. Press , [1], [2] to select Test Mode 2. This puts the transceiver into short alert mode, with escalert, call comparator and extended alert suspended. The RIC is changed to 1-1501. Note that the original RIC is stored and reinstated on leaving test mode. When the transceiver is called, a single 1.0s alert tone is generated. The message `Test-Mode 2' will be displayed.

TEST MODE 3

10. Press , [1], [3] to select Test Mode 3. This puts the receiver into speech mode (i.e. audio on permanently with squelch circuits defeated). The receiver will stay in this mode until this test mode is defeated; all other functions are as normal. The message `Test-Mode 3' will be displayed.

TEST MODE 4

11. Press , [1], [4] to select Test Mode 4. This puts the transmitter into continuous speech mode. The transmitter will stay in this mode until this test mode is defeated; all other functions are as normal. The message `Test-Mode 4' will be displayed.
