(telephone-style) mode. 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.
RPR 563GS/KGS Message Storage 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 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.

RPR 563GS/KGS The transceiver has the following indicators: A 14-character alphanumeric display. This displays selective call messages, and transceiver and system status messages. Tx KEY Lights when the transmitter is active. ALERT Lights when a selective call has been received.
RPR 563GS/KGS Removal is a reversal of the above procedure, but press the battery button before releasing the battery pack. Switching On 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.
RPR 563GS/KGS 11. The displayed message comprises combinations of the following elements: Element Example Time stamp + space 12:00 Beep Code (Tone Only message) Speech call Call ended Beep code alpha Fire Off-Air Message (Alpha) Please call reception Message Terminator ** or **? 12.
RPR 563GS/KGS 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.
RPR 563GS/KGS 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 inhibit operation because of feedback. In this situation a PMR-style of operation is desirable.
RPR 563GS/KGS 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.
RPR 563GS/KGS 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 dialling tone has been received, the telephone number may be dialled as if calling from another telephone.
RPR 563GS/KGS 45. If a team call is transmitted, or another user makes an emergency "Burst-In" call, the system will override and terminate the call without prior warning. The transceiver that has been overridden will display the message "Call Override".
RPR 563GS/KGS 52. If the interrogation is unsuccessful there are two possibilities: If there is no contact between system and transceiver, the following display is shown: Absent or PROGRAMMED MESSAGE If there is no user number associated with the transceiver address the following...

RPR 563GS/KGS CIRCUIT SUMMARY 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.
RPR 563GS/KGS RADIO BOARD Power Supplies Battery Voltage (B+), TxB+, SPEECH3V and the +4.5V supply lines are derived from the Decoder Board and are available at PL301. 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).
Page 35
RPR 563GS/KGS 15. Output from FL304 is amplified by the first amplifier in IC302 before application to a second 455kHz filter FL305. The signal is then fed back into IC302 for further amplification and application to the internal quadrature discriminator.

Page 37
RPR 563GS/KGS 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 also applied to IC306b for amplification, rectified by D303 and C451, and applied to TR341, which mutes the speech circuits from the microphone.
Page 38
RPR 563GS/KGS DECODER BOARD Power Supplies 30. 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.
Page 39
RPR 563GS/KGS Receiver Audio Stages 34. 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.
Page 41
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.
