RADIO VOLUME ADJUST The RADIO VOLUME ADJUST is a one time setting which depends on the radio connected and its normal volume. The siren cover must be removed to access the adjustment. The cover is held in place by a snap-fastener on the back of the unit. While holding the case on the sides press hard with your thumbs on the back of the unit. The chassis will slide out the front. Switch siren to RADIO mode and turn on the power. With the volume on the radio itself set to normal level, set the RADIO VOLUME ADJUST to the RADIO VOLUME ADJUST desired level. Turn off power and press the chassis back into the cover. TB0324B Page 5 of 7 10/18/03 SERVICE This unit is designed to provide years of reliable service under even the worst conditions. Many times there may appear to be a problem with the unit when the true problem is in the speaker(s) or improper installation. The following chart shows typical symptoms and possible causes. A blown rear panel fuse doesn't necessarily mean that the unit is bad. If a speaker or speaker lead is shorted this fuse will blow before the unit is damaged. Disconnect the SPKR leads and replace the fuse. If the siren emits a sound when in the Yelp position it is OK. Check the speaker(s) or leads for possible shorting.
