Microphone Gain

This screen displays the setting of the microphone gain of the beltpack. There are 16 possible settings. The number 0 indi- cates no microphone gain, the number 15 is maximum gain. Each step is about 3 dB of audio.

Adjusting the Microphone Gain

1.Push <SET> at the microphone gain screen. The num- ber will begin flashing.

2.Select the desired gain with the <UP>/<DOWN> ar- row buttons.

3.Push <SET> to place the unit at the indicated micro- phone gain.

Transmit Power

The transmit power screen displays the current setting of the beltpack transmitter’s output power level. There are three set- tings.

Transmit Power Settings

 

The beltpack’s transmitter adjusts it’s output level according

Auto (Default)

to information sent to the beltpack from the base station.

NOTE: A decimal point in the display indicates the

 

transmitter is at high power, no dot means the unit is at low

 

transmit power.

High

The beltpack is transmitting at full power, nominal 50 mW,

 

constant.

 

The transmitter is at low power, nominal 5 mW, constant.

Low

When the unit is set to auto the beltpack will set it’s power set- ting according to information being sent from the base station. The base station information will tell the beltpack the appro- priate power setting to use based upon received signal strength level at the base station from the beltpack. By reducing the transmit power when possible, the battery life of the beltpack can be slightly extended. Also intermodulation products can be reduced.

Changing the Transmit Power Setting

1.Push <SET> at the transmit power screen. The power setting will begin flashing.

2.Select the power setting with the <UP>/<DOWN> ar- row buttons.

3.Push <SET> to place the unit at the indicated setting.

Encryption Code

The encryption code screen allows the setting of four hexadec- imal digits. Any combination of letters and/or numbers may be selected. The beltpack’s code must match the base station’s code for audio recovery. This code along with the serial num- ber encryption code discussed on the next page, means there is over 4 billion possible code combinations.
