MUSIC VOLUME

The MUSIC VOLUME control adjusts the volume of background music. Rotate the control counterclockwise to decrease the level. Rotate the control clockwise to increase the level.

MIC VOLUME

The MIC VOLUME control adjusts the microphone level. Rotate the control counterclockwise to decrease the level. Rotate the control clockwise to increase the level.

TEL VOLUME

This control adjusts the telephone paging level. It does not affect the microphone level. Rotate the control counterclockwise to decrease the level. Rotate the control clockwise to increase the level.

Maintenance

CAUTION

There are no user-serviceable parts within the amplifier. Have all internal servicing performed by a qualified techni- cian. The warranty may become void if repairs are per- formed by anyone other than the Bogen Factory Service Department.

Circuit Breaker

If the circuit breaker trips, the POWER LED will go out and there will be no output. Unplug the AC line cord. Remove the cover of the output connections bay and press the red Circuit Breaker button to reset it. Replace the cover and plug the line cord back into the outlet. If the breaker trips again, have the trouble investigated by qualified personnel.

ALC

The telephone paging channel has an ALC circuit that maintains constant output level regardless of input variations in the vary- ing voice levels of persons using the system. The ALC is factory set and adjustments are not normally required. If ALC is required, set the ALC control using the directions below.

1.Turn off the ALC by rotating the control fully counterclock- wise.

Thermal Protection

If the thermal protection activates, there will be no audio out- put but the POWER LED will remain on. Wait approximately five minutes for the amplifier to cool. If the amplifier overheats again, investigate the cause of the over-temperature condition. This may be due to improper connections at the output terminals or excessive environmental heat due to inadequate ventilation.

2.Set the TEL VOLUME control to the highest level likely to be required. Hold a telephone handset in a normal position and speak softly yet distinctly into the mouthpiece. Adjust the TEL VOLUME control to the desired output level.

3.Speak in a loud voice directly into the handset mouthpiece while rotating the ALC control clockwise to the point where the output of the amplifier is reduced to the same level as that obtained in Step 2.

To vary the overall volume without disturbing the ALC adjust- ment, use the TEL VOLUME control.
