INITIAL START–UP AND OPERATION
4.2
The following text presents initial start–up and operating procedures.
1. Apply power to the unit.
The POWER indicator will illuminate. The AFC LOCK indicator will illuminate when the unit locks to a
frequency. The UNSQUELCHED indicator will illuminate if the unit signal level is above the squelch point. The
MAX SIG level indicator will illuminate if no attenuation is applied. The ATT indicator will illuminate if
attenuation is applied.
2. To change the operating frequency, proceed as follows:
A. For SR–30 units, proceed as follows:
1. Depress the FREQUENCY SELECT switch.
The unit will toggle from one frequency to the opposite frequency as indicated by the F1/F2
indicators. The AFC LOCK indicator will flash quickly to indicate the unit has changed
frequencies.
2. To change to the opposite frequency, wait approximately 1 second, then depress the
FREQUENCY SELECT switch.
B. For SR–40A units, proceed as follows:
1. Determine the 9 digit operating frequency. Use the 9 FREQUENCY SELECT switches to
enter the frequency.
2. Depress the EXECUTE switch.
The AFC LOCK indicator will flash quickly to indicate the unit has changed frequencies.
3. If squelch adjustment is required, use the SQUELCH LEVEL control to adjust the unit to the desired
squelch point.
4. To view the program audio on the multimeter, operate the multimeter switch to MONO PROGRAM
LEVEL.
The audio will appear on the multimeter.
5. Adjust the program audio output level to the desired level using the MONO PROGRAM LEVEL control.
6. Use the multimeter to monitor the SIGNAL LEVEL, DECODE LEVEL, POWER SUPPLY LEVEL, or MONO
PROGRAM LEVEL as required.
