Checking the Charger
To check the charger, do the following:
1. Turn off the AC power to the control cabinet.
2. Measure the overall battery voltage between Battery 1 (negative) and Battery 2
(positive). The battery voltage should be 25 to 27 Vdc (nominal).
3. Turn on the AC power to the control cabinet.
4. Measure the overall charger voltage between Battery 1 (negative) and Battery 2
(positive). Ensure the voltage is rising up to 27 Vdc (nominal).
NOTE
: If your GUEST charger is not working, you may need to replace it. Call Federal
Signal for the Battery Charger Retrofit Kit Q860000236 for UV Cabinet.
Adjusting Two-Way Radio Receiver
This procedure is completed at the factory. Only complete this procedure if radio re-
alignment is required or the radio is installed in the field.
Qualifications
Radio shop and/or a properly trained radio technician.
Equipment Required
1. Service Monitor
2. Oscilloscope
Setup
Connect the Unit Under Test (UUT) to the service monitor.
Adjusting the receive audio
To adjust the receive audio, do the following:
1. Using a service monitor, modulate the correct RF signal into the receiver with a
1 kHz tone
a.
If bandwidth is 12.5 kHz (typical), then modulate at 1.5 kHz deviation. If
using private line, add 0.375 kHz private line deviation to the signal.
b. If bandwidth is 25 kHz, then modulate at 3 kHz deviation. If using private line,
add 0.75 kHz private line deviation to the signal.
2. Adjust the level at TP16 (UV+ controller card) for 1 V
p-p
using the REC gain
adjustment R105 (UV+ controller card front panel. See Figure 2).
