ROLE
1. The Multitone RPR 561K radio paging transceiver comprises an HF receiver and VHF transmitter, allowing paging and two-way speech facilities. The unit can receive alphanumeric paging messages and can 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 is available, designated the RPR561, which is able to make limited telephone-style 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 561
TM1200 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.
Time-of-Day
11. The Time-of-Day is displayed in hh:mm format. The transceiver has an internal clock
which is synchronised by time information from the last valid Mk7 paging call. At switch-on, the clock will not be synchronised until the first Mk7 call is received. The transceiver will display the characters “-:-” before synchronisation occurs.
Automatic Speech Switching
12. Allows speech to follow automatically after an alert tone.
RPR 561
TM1200 Issue 1Page 1 - 4
Battery Economy Circuit (BEC)
13. 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
14. The direction of the display may be changed to suit the way in which the transceiver is carried.
Engineering Mode
15. 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
16. When a battery pack is fitted and the Permanent On option enabled, the transceiver cannot be switched off.
Alert Duration
17. 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)
18. 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 volume.
Extended Alert
19. 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.
RPR 561
TM1200 Issue 1 Page 1 - 5
Group Call
20. 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.
Call Comparator
21. Prevents the transceiver from reacting to an identical message received within a pre-
determined period. Options are none, 30s, 120s, 300s or disabled.
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 561K 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 561
TM1200 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".

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 561
TM1200 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".
23. This mode is possible only when the call is to, or from, a telephone.

Loud Speech (Simplex)
24. 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, simplex operation is desirable. When calling another transceiver, only simplex operation is possible.
25. 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
26. 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
27. Cancel the alert by pressing the button. The beep and LED alert cease but the
message is replayed from the beginning.
Escalating Alert
28. 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.
29. 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.

Table 2: Beep Code and Alert Patterns
* 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 time, or for four seconds if it is a speech call.
NOTE: Silent Alert is not currently supported by Access 3000 systems.
Extended Alert
30. 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.

Memory Replay
31. 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.
32. 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.
33. 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'.
34. 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)
35. 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.
36. 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.
37. The line request can be cancelled at any time by pressing .

38. On reduced keypad versions, connection to the designated point is automatic once has been pressed.
Making a Call to a Telephone (RPR 561K only)
39. 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 561K only)
40. The procedure for making a call to another mobile is as detailed in paragraph 34. If the call is to another paging receiver, the paging system access number must be dialled, followed by the user number and numeric message when requested by the paging system.
41. 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.
42. 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 561K only)
43. 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.
44. Connection of reduced keypad transceivers to designated MCUs is controlled by the paging system.
Terminating a Call
45. To terminate a call, press . The transceiver sends its Un-Talk code, displays the message "Call Ended" and reverts to quiescent state.
46. 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 561
TM1200 Issue 1 Page 2 - 13
47. 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
48. 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
49. 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
50. 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.
51. 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.
52. Brand new battery packs normally require a few charge and discharge 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.
