Adjusting Relative PA Loudness

After the electronic siren is completely installed in the vehicle, set the Selector switch to

MANUAL. Press the microphone push-to-talk switch, speak in a normal voice, and adjust

the GAIN control for the desired sound level outside the vehicle. Turn on the vehicle’s

two-way radio and adjust the volume to a comfortable listening level inside the vehicle.

Then set the Selector switch to RADIO. Stand outside of the vehicle and note the radio

rebroadcast loudness. If the sound volume is too loud or too soft, using a small, flat

blade screwdriver, adjust R39 from the back of the siren to the desired sound level. See

Figure 7.

Figure 7 Relative PA Loudness

R39

290A4452-08

After the adjustment is completed, the loudness of the radio rebroadcast and public

address may be varied with the front panel GAIN control.
