1. Introduction
1.1 The UHF singleway radio is ideal for use in all types of financial, or commercial premises
where staff need the security of a personal attack system and also the freedom of mobility.
The 7703 is a versatile compact UHF receiver for use with a selection of transmitters. These
receivers can store up to 48 transmitter identification numbers.
1.2 There are 3 types of transmitter which are compatible with the 7703 these are, the portable,
the money clip and a contact operated model, each have a typical range of 250 metres.
The alkaline battery fitted will offer approximately one year’s battery life, dependent on
frequency of use.
A brief list of the features offered by the 7703 receiver is as follows:
(a) LED display of Alarm, local and transmitter battery low.
(b) Radio blocking interference detection.
(c) Aerial tamper detection.
(d) Anti false alarm.
(e) Power supply failure warning.
(f) Key switch for clear, reset and test.
(g) Outputs from programmable Alarm and Local relays.
(h) Low power operation.
(i) Programmable audio warning.
1.3 The internal view of the 7703 receiver is shown below in Figures 1, 2 and 3

2. Installation Instructions
Before installing the 7703 receiver read these instructions with care.
2.1 When choosing a suitable site for the 7703 consider the following:-
(a) The minimum recommended distance of metal objects or equipment from the aerial is
400mm.
(b) The minimum recommended distance to photocopiers, computers and fax machines is
2 metres.
2.2 Having chosen a suitable site, place the receiver in or near its final position. Fit the special
aerial provided and connect power to the receiver as per the provided connection drawing.
On power-up the 7703 will self test. The self test will cause the internal sounder to sound for
approximately 1 second. In addition the front panel LED's will light momentarily in the
following order: Clear LED, Test LED, Power LED, Radio Interference LED, Low
Battery LED, Local LED and Alarm LED. This cycle will be repeated a number of times.
The number of repetitions determines the state of the receiver as shown in Table 1.
Cycles Radio Status
3 EEPROM OK. Clear LED steady means transmitters in memory
3
EEPROM OK. Clear LED flashing means no transmitter's in
memory
1 EEPROM failure
Table 1
The above sequence of events will also occur if the reset button on the receiver board is
pressed.
2.3 To check for radio interference using the integral carrier detector, turn the keyswitch to the
TEST position. The red RADIO INTERFERENCE LED will light if spurious radio signals are
present. Re-site the 7703 if necessary.
2.4 Load the serial identities of the transmitters to be used with the system, see section 4.2.
2.5 Check the signal from each transmitter can reach the receiver from their intended locations.
