INTERRUPTIVE SELF-TEST ROUTINE
119 This test is initiated by pressing the TEST key. During the self-test routine, normal operation of the
equipment is suspended, and the TEST indicator is on.
120 At the start of the test, the fault memory is cleared and the MEM indicator is turned off. If a fault is
found, the module and test point number is stored in the fault memory, and the MEM indicator turned on.
The test routine then proceeds to the next module.
121 On completion, one of the following status messages is shown on the MONITOR display:
PASS - indicating system is fully operational.
bit - indicating one or more out of limit conditions exist.
tCAr - indicating the interruptive test has been aborted. The transmitter’s carrier output power
is below specification, i.e. less than 4 watts (not applicable to receivers).
tAUd - indicating the interruptive test has been aborted. The transmitter’s depth of modulation
is below specification, i.e., less than 50% (not applicable to receivers).
rSEn - indicating the interruptive test has been aborted. The receiver’s sensitivity is below
specification (not applicable to transmitters).
rAUd - indicating the interruptive test has been aborted. The receiver’s audio is below
specification (not applicable to transmitters).
ANT 1 - indicating high VSWR present at the VHF antenna connection.
ANT 2 - indicating high VSWR present at the UHF antenna connection.
°C - indicating equipment above normal operating temperature.
PS - indicating low supply voltage AC or DC as selected.
EbIt - indicating an external error has occurred. When an external power amplifier type 3640 is
connected to the radio and this message is received, the 3640 is switched to the bypass
condition (non-amplifying). When the fault is cleared in the 3640, the following key sequence
must be entered at the radio to clear the 3640 bypass condition and restore normal working of
the 3640:
SHIFT s, RESET
Note ...
During antenna testing it is not possible for the equipment to indicate a fault on both VHF and UHF
antenna systems simultaneously. Should this situation occur, the first detected fault will be
displayed on the monitor. It is therefore advisable to check both antenna systems independently in
the event of a failure indication.
