1.1 INTRODUCTION
The Multitone RPR 583 pager is a UHF receiver for On-site applications. The pager

receives alpha-numeric messages sent in Multitone Mk7 digital format.
The front panel of the unit has a Liquid Crystal Display (LCD) to display messages

and other information. The unit has a choice of fonts for the LCD which the operator
can select. The three buttons on the front panel are used to control the functions
of the unit.

If the unit receives a message which has more characters than the display can show,
the excess characters are stored. The front panel buttons are used to transfer the
stored part of the message to the screen as required.

Message alert is provided by an audible beep tone and/or by the unit vibrating. The
front panel buttons are used to select the preferred alert (where this option has been
enabled).

Power for the unit is supplied by a single AAA battery. The unit has the facility to be
used with an ‘absence/charging’ rack. The external contacts provide the interface
for charging the rechargeable battery (where fitted) and for the exchange of data
between the unit and the base station. A door on the rear of the unit gives access
to the battery compartment.

A back-up supply for the unit is available when the battery is changed. The back-up
supply is provided by a large-value capacitor, mounted on the decoder board in the
unit. The capacitor, when fully charged, can maintain data in the unit for more than
5 minutes.

The unit case is a 2-piece plastic moulding secured by two cross-head screws. A
lanyard is supplied with the unit which can be fastened to the case and the attached
clip used to secure the unit to a suitable object e.g. belt, or the holster also supplied.

2.3 RECEIVING AND STORING MESSAGES

2.3.1 Introduction
The unit is programmed with four RIC addresses which are set to receive different

types of message and which have different audible alerts.
RIC1 Receives personal messages.

The audible alert uses Multitone Beep Codes. Optionally, RIC1 may be
programmed to receive ‘personal alerts’. With this option, the alert is
chosen by the operator from seven allocated sounds (see paragraph

2.2.5).

RIC2 May be programmed to receive personal messages or to receive group

and ‘all call’ messages.
The audible alert uses Multitone Beep Codes plus warble.

RIC3 May be programmed to receive personal messages or to receive group or

‘all call’ messages.
The audible alert uses Multitone Beep Codes only.

RIC4 Receives information services. A maximum of eight information services

can be accommodated, with each service storing a maximum of ten
messages. Optionally, each service can be programmed to determine the
number of messages it can store.

The audible alert can be programmed ON or OFF for each information
service.

The unit can receive tone or alphanumeric messages sent on one of the Multitone
Beep Codes. Group calls can be allocated for a maximum of 10, 100 or 1000 users.

2.3.2 Receiving a Message

When the pager receives a new message the first part of the message shows on the
display and the alert operates. If the standby screen is not showing when the
message is received, or if another message is on the screen, the new message will
be put in the Message Store.

Push any button to acknowledge receipt of the message and to stop the alert.

RPR 583

TM1212 Issue 1 Page 2 - 15

If the call is not acknowledged, the pager may be pre-programmed to give a short
alert every two minutes until the battery is exhausted.

If the message is longer than the screen can show, push the O> button to show the
next part of the message. Repeat the procedure until the end of message symbol œ
shows.

To process the message, push the O> button again to show the Reviewing Stored
Messages menu (refer to paragraph 2.3.3).

To return to the standby screen, push and hold the O> button for one second or wait
for the unit to time-out. If the message has not been read, the standby screen will
show the symbol.

2.3.3 Reviewing Stored Messages
To display the received messages, starting with the newest message, push the

- button. The message is displayed with its time and date stamp. If the message

is longer than the screen can show, push the O> button to show the next part of the

message. To read another message, use the ¬ or - buttons.

When the last part of the message is shown, push the O> button. The display shows
three symbols:

To read the message again, use the ¬ or - buttons to select the first symbol then

push the O> button.

To delete the message, use the ¬ or - buttons to select the second symbol then

push the O> button. The display shows the delete symbol plus a flashing ? symbol.
Push the O> button again to delete the message.

To put the message in the Archive Store, use the ¬ or - buttons to select the third

symbol then push the O> button. The display shows the archive symbol plus a
flashing ?. Push the O> button again to transfer the message to the Archive Store.

To return to the standby screen at any time, push and hold the O> button for one
second or wait for the unit to time-out.

The unit memory can hold a maximum of 64 messages. When this number is
reached the standby screen shows the memory full symbol.

If a new message is received when the memory is full, the oldest message is deleted.
Messages which have been read will be deleted before unread messages.

Figure 3.1 RPR 583 Block Diagram

3.1 CIRCUIT SUMMARY
The RPR 583 message receiver consists of two Printed Circuit Board (PCB)

assemblies contained in a plastic case.
The case is constructed in two main parts, the case front and the case back. A

cover on the back of the RPR 583 provides access to the battery compartment. The
two boards in the case are:

a) The Radio Board which has the Dual Conversion Receiver, the 1 volt

regulator and the audio alert output circuit and transducer.

b) The Decoder Board which has the microprocessor, the Decoder Oscillator,

the EPROM, the SRAM, the Liquid Crystal Display Module, the LCD
illumination lamp, the vibrate motor and the primary and backup power
supplies.

The block diagram of the functional areas of the RPR 583 is shown in Figure 3.1.
Refer to Section 7 for the circuit diagram and board layout information.

RPR 583

TM1212 Issue 1 Page 3 - 3

The RF signal enters the aerial and is fed to the dual conversion superheterodyne
receiver. The signal is demodulated from RF to baseband frequencies, converted
to digital format and is then fed to the decoder. This results in the received data
activating the memory, display and the selected audible alert or vibrate alert.

To prolong the life of the battery, the receiver operates with battery economy mode.
When the unit is in standby mode, the receiver is powered up at regular intervals
(equivalent to once per batch) to allow the decoder to search for pre-amble. While
the unit is receiving preamble on its allocated channel, the receiver remains powered
up. This allows the decoder to search for a SYNC word. When the SYNC word is
found, ‘batch lock’ is achieved. In batch lock the receiver is only powered up during
the allocated frame to allow the MK7 decoder to search for its address. If the
address is found, the receiver stays ON for the duration of the message.

3.2 DUAL CONVERSION RECEIVER

The incoming RF signal is received by the aerial AE401/AE402 which is tuned by
CV404. Capacitors C401 and C441 provide matching to RF amplifier TR401,
TR402. R401, R402 and TR407 provide AGC.

RPR 583

TM1212 Issue 1 Page 3 - 5

Output from the RF amplifier passes through an image filter which provides these
functions:

a) Attenuation of the first image frequency.
b) Attenuation of signals outside the required band.
c) Matches the output impedance of the RF amplifier to the input impedance of

the mixer stage.

C406, L401 and CV407 form a parallel tuned circuit with the resonant frequency
adjusted for minimum loss at the frequency of operation.

C428, CV406 and L407 also form a parallel tuned circuit adjusted for minimum loss
at the frequency of operation. In addition, C428 and L407 form a series resonant
circuit with the resonant frequency close to the first image frequency. The complete
filter network gives approximately 40dB of attenuation at the image frequency.

The local oscillator comprises transistor TR410, crystal XL402 and associated
components. Frequency adjustment is by CV405. The local oscillator frequency is
calculated as follows:

carrier frequency - 45MHz

fx =

3

where fx is the crystal frequency in MHz.

The collector of TR410 is tuned to the third harmonic of XL402 by L411 and C459.
The circuit provides the correct Local Oscillator frequency and reduces the level of
2nd, 4th and higher harmonics. The two tuned circuits, L413, C463 and L415, C464
give further filtering of unwanted harmonics.

The mixer circuit, TR403 and associated components, receives the output of the
image filter. This is mixed with the local oscillator output to produce a 45MHz
product which is selected by the resonant circuit L406, C451. The 45MHz output
passes through a monolithic crystal filter, FL401, which has a bandwidth of ±7.5kHz
at the -3dB points.

The output from FL401 is fed to IC401 pin 24. IC401 is a combined mixer/ local
oscillator/IF/detector.

The second oscillator runs at 44.545MHz (45.455MHz for Band 4) and, with the
exception of XL401 and its associated components, is built into the IC. As the
second oscillator is not trimmed, small frequency errors are absorbed when tuning
the first local oscillator.

The input at pin 24 is applied to the internal second mixer, and is mixed with the
second oscillator output to produce a 455 kHz 2nd IF signal at pin 3. The IF signal
then passes through two ceramic filters FL402 and FL403 which remove unwanted
mixer products and provide further selectivity.

RPR 583

TM1212 Issue 1

Page 3 - 6

The output from FL403 is split: one output connects through C450 to pin 6 of IC401
and the IF amplifier; the other connects to the Received Signal Strength Indicator
(RSSI) circuit in IC401 through C419, R407 and pin 5.

Due to the characteristics of filters FL401, FL402 and FL403, the signal at the input
to the IF amplifier has amplitude modulation (AM). The AM must be removed before
the signal reaches the detector stage. This is performed by the IF amplifier in IC401
which has very high gain and is designed to limit the amplitude of the signal to
remove the AM component and give a ‘square’ output. C479 and C480 provide
de-coupling for the amplifier.

The output from the IF amplifier passes to the detector in IC401. This circuit is a
Quadrature Demodulator which has two inputs. One input connects directly to the
IF amplifier, the other receives the signal from the IF amplifier through a phase delay
circuit connected to pins 9 and 10 of the IC. The phase delay depends on the
frequency of the IF signal and is 90 degrees at the centre frequency of the unit’s
allocated channel. The phase shift is provided by ceramic discriminator FL404,
capacitor C426 and resistor R416.

The RSSI circuit in IC401 provides an Automatic Gain Control (AGC) signal for the
receiver. The circuit detects the received signal strength and gives a DC current
out. R407 sets the level at which the circuit starts to operate. The value of 68
kilohms sets it to approximately 16dB above the sensitivity threshold. The DC output
from pin 22 of the IC connects to the AGC control circuit. When there is no RSSI
output, transistor TR407 is biased on and keeps the RF amplifier at full gain. At
strong signal levels the output from the RSSI causes TR407 to cut off gradually, thus
reducing the gain of the RF amplifier. C437 determines the rise and fall times of the
AGC.

The output from the detector stage, pin 11, gives an audio output to TP401. This
test point is used in the final stages of production to align the receiver circuits.
TP401 is also used to program the decoder section of the unit and connects to the
microprocessor (IC3) on the decoder board through PL401/SK1, pin 13. In addition,
pin 13 connects to the external PROG connection on the back of the unit, which
allows the microprocessor to communicate with the paging management system,
when the unit is in the ‘Absence/Charging Rack’.

Pin 11 of IC401 also connects to pin 12 through R425, R429 and R428. These
resistors together with capacitors C448, C483, C484 and the internal filter amplifier
of IC401 form the data filter; a unity-gain, low-pass filter which reduces high
frequency noise. The output of the filter amplifier connects internally to the FSK
Comparator. The data output of the comparator, pin 18, connects to microprocessor
IC3, pin 36 through PL401/SK1, pin 11. A logic signal from IC3, pin 58 to IC401, pin
16 controls the Fast/Slow charge of the comparator. The logic level at pin 16 is
always set high.

Figure 3.3 Decoder Block Diagram

3.3 DECODER

3.3.1 General

The Decoder comprises the Decoder Oscillator, Microprocessor, EEPROM, SRAM
message memory and switches, plus support components and a separate LCD
module. The signal from the receiver is processed by the decoder software in the
microprocessor. The microprocessor stores the information in the SRAM, IC4,
before activating the selected alert and sending the message data to the LCD
module for display. The EEPROM holds information applicable to the unit.

3.3.2 Message Decoder
The Microprocessor, IC3, contains software to process data signals received in

Multitone Mk7 format. When no valid signals are received by the unit, the system
goes into a standby mode to reduce power consumption.

RPR 583

TM1212 Issue 1

Page 3 - 8

3.3.3 Microprocessor
The microprocessor controls the functions of the unit. A 4.19MHz clock controlled

by XL1, provides the basic timing for the system.
A second clock (TR5, TR7, XL2) provides pulses at 32.768kHz, to operate the

microprocessor while it is in standby mode.
Data received from IC401 is processed by the microprocessor and stored in the

SRAM chip, IC4. The microprocessor then causes the selected Alert to operate and
sends the message to the LCD module for display. Outputs from pin 5 (LCD-CS),
pin 39 (AD17), pin 38 (AD16) and pin 60 (/WR) control the transfer of data to the
LCD module. Outputs from pins 2, 7 and 8 control the operation of the audio alert,
the vibrate motor and the display backlight lamps.

IC3 also controls the internal functions of the system, displaying the symbols and
changing the modes when selected by the three buttons on the front of the unit.

Putting the unit in the rack also connects the microprocessor’s PGM input (pin1) to
the paging system controller through the PROG contact at the rear of the unit. This
allows communication between the unit and the system controller.

3.3.4 EEPROM
The EEPROM (IC1) holds information applicable to the unit, such as: Serial Number;

RIC codes; Radio parameters; Programmed options. The information is sent to the
microprocessor through the serial data link, pins 62, 63 and 64.

3.3.5 SRAM
The SRAM (IC4) is a 256 k device which can store up to 32 k of 8-bit information.

Address lines AD00 through AD14 and control lines RAM-CE and /WR from the
microprocessor, control the flow of data in and out of the device.

3.3.6 LCD Module
The LCD Module is a single device which contains all the necessary circuits to

produce the alpha-numeric characters and the symbols for the integral display.
Address lines AD16 and AD17 and control lines LCD-CS and /WR from the
microprocessor, control the flow of data to the device.

C20 and C21 (pins 27 through 30) are part of the internal DC/DC converter of the
module’s negative bias supply.

R11, R12, R13, C17 and C22 through C25 are part of the circuit which controls the
voltage to the LCD driver.

RPR 583

TM1212 Issue 1 Page 3 - 9

3.3.7 Display Illumination
One miniature lamp is used to illuminate the LCD display. The lamp is selected ON

or OFF using the buttons on the front panel. The ‘Lamp ON/OFF’ signal, which
comes from pin 8 of the microprocessor, controls transistor TR2 in the lamp circuit.

3.3.8 Alerts
a) Audible Alert (Beep)

The transducer, SP401, and the driver circuits TR415 and TR416, are installed
on the radio board. The audible alert signal from IC3, pin 2 connects to TR415
through SK1/PL401 pin14. The alert can be selected ON or OFF using the
buttons on the front panel.

b) Vibrate Alert

The vibrate motor is operated by transistors TR3 and TR4 on the decoder
board. The vibrate alert signal from IC3, pin 7 connects to pin 1 of TR3. The
alert can be selected ON or OFF using the buttons on the front panel.

3.4 POWER SUPPLIES
The primary power supply for the unit is a single 1.5 volt, AAA battery (BAT1). The

supply from the battery (B+) connects directly to the lamp and vibrate motor circuits
that require relatively high currents. B+ also connects to the radio board through
SK1/PL401, pin 9 and to the voltage converter, IC6, on the decoder board.

IC6 and its associated components supply the +3.0 volts (VDD) for the unit. In
addition, the circuit charges the backup supply (BAT2) through resistor R6. Double
diode D2 provides isolation for the two circuits.

IC5 is configured to monitor Vdd and resets the decoder circuits if the voltage would
cause data corruption.

Transistor TR1, connected to pins 6 and 15 of IC3, detects the battery voltage. If
BAT1 is removed, the drop in B+ causes transistor TR1 to switch OFF which sets the
microprocessor to low-current mode. In this mode BAT2 supplies sufficient power
to keep the microprocessor and the SRAM operational for more than 5 minutes.

The 1 volt supply for the receiver circuits is provided by transistor TR406 and its
associated components. The circuit is a series regulator and is maintained within

specification by a control circuit in IC401.

5.7 FAULT FINDING

5.7.1 General
Refer to the Fault Finding Guide (Figures 5.5 through 5.7) and the information given

in Tables 5.1 through 5.9 and Figures 5.8 through 5.11 to help resolve problems.
Alignment information is in paragraph 5.8. Programming information is given in
paragraph 5.9.

Faults can be caused by user negligence. Always check the unit for these faults:
a) Damage to the Case or LCD
b) Water damage
c) Corrosion damage or leaking battery
Any metal parts which are corroded must be removed. Clean the affected area of the

Board assembly with a non-corrosive contact cleaner. Dry the area with a low­pressure flow of warm air (40 EC through 50 EC). Install new parts.

5.7.2 Fault Diagnosis
Put a known good battery in the unit and switch ON the unit. Refer to the Fault-

Finding Guide (Figures 5.5 through 5.7). If it is suspected that the Decoder Board
is faulty, proceed as follows:

a) Remove the Board Assembly from the case (see paragraphs 5.5.1 and 5.5.2).
b) Separate the Decoder Board from the Radio Board (see paragraph 5.5.3).
c) Disable the Battery Economy function by installing a 0 ohm resistor in the

position for R456 (side 2 of the radio board near IC401).

d) Use the 14-way lead (supplied with the P671B) to connect the two boards (refer

to Figure 5.4)

e) Put the boards on an anti-static mat and connect a 1.5 volt supply to the

Decoder Board. Switch ON the power supply.

f) Connect a ’10-times’ probe to the oscilloscope and measure the points given

in Table 5.4. Compare the waveforms on the oscilloscope with those shown in
Figure 5.9.

5.7.3 Power Supply Voltage Adjustment
There is no adjustment for the 1 volt, 1.5 volts or 3 volts power supplies.

(beep and vibrate for one second and show the programmable switch-on
message for three seconds). After approximately two minutes the low battery
symbol will appear.

c) Switch OFF the unit. Set the output of the variable DC power supply to

1.2 volts.

d) Switch ON the unit. Make sure that the unit goes through the normal ‘start-up’

procedure.

5.8.3 Pager Sensitivity Measurement (Coarse)

To determine the pager sensitivity, configure the test equipment as shown in
Figure 5.14 and do the procedure given in sub-paragraphs a) through e).

NOTE: This is only an indication of sensitivity, which is dependant on the unit under

test being in a noise free environment.

a) Set the signal generator to the channel frequency, at a deviation of 4.5kHz and

an output level of -85dBm.
b) Install a known good battery in the pager and switch it ON.
c) Put the pager in the P671A and send a sensitivity call from the P645. Increase

the signal generator output level, if necessary, to obtain a correctly received

call.
d) Reduce the RF level in 1dB steps until the pager receives less than three calls

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

output level of -98dBm should be achieved.

5.8.4 Pager Sensitivity Measurement (Fine)
