Problem
Action
No Radio Decode
• Unit was not armed before sending a DTMF function code
or unit is not programmed to recognize that particular code
sequence or signal is not being received properly.
• Verify programming is correct. Check the received audio signal
quality at the RX test pin on the front of the control
card
.
No Two-tone decode Decoder not programmed. Check radio connections if external (see
the wiring diagram).
Check for proper C/D polarity setting. Insure that radio is working
properly by using a service monitor to inject a strong, clean signal.
Check transmitter deviation.
Low output from
speaker array
Check battery voltage. Check speaker impedance (see the
Maintenance section).
Also, check signal indicators on amplifiers during a function. If
indicators are off, remove amplifier for service.
Function stops
before normal
timeout
Batteries may require further charging. Check battery voltage under
load. Check charger output.
Local PA feeds back Lower PA volume using knob above MIC connector.
Local PA has little or
no output
Hold MIC close to mouth. Increase PA volume using knob above
MIC connector.
Batteries not holding
charge
Check that charger fuses are intact and check charger output.
Load test batteries.
EOWS*612 does not
rotate
Check that the rotation relay on the backplane motherboard is
operating (indicated by LED D2). Also check fuses F1 and F2 on
the backplane motherboard.
Radio PA takes too
long to timeout
Check radio for proper operation of squelch.
CD LED should light while carrier is present
Landline activation
inputs do not function
Verify minimum 0.5 second contact closure is applied to JP14 on
the backplane motherboard.
Options
This section describes the options you can use with the UV controller.
Model UVARM
The UV supports an optional Audio and Relay Output Module (UVARM) that provides
three audio outputs and four relay outputs to enable the UV to connect to existing PA
systems or other auxiliary devices. The outputs consist of a balanced 33 ohm, a balanced
600 ohm, a selectable 600 ohm balanced or single-ended line level output and four SPDT
relay outputs. The level of each audio output is independently adjustable. Each audio and
relay output is individually addressable allowing each output to be activated at different
times.
