BASE STATION OPERATION

Front Panel Controls, Indicators and Connector

1. POWER Switch

Press the upper part of the switch to turn the power on. A red light on the switch will be lit when the base

station power is on. Press the lower part of the switch to turn the power off. The red light will go off. All

settings are preserved when the power is turned off, and will be restored when the power is turned on again.

2. Beltpac Registration Controls and Status Indicator

Use these controls to register each Beltpac used with a specific base station, as described on pages 7 and 8.

3. UNLATCH Button

Use this button to unlatch all Beltpac transmitters. (Beltpac users can “latch” their Beltpacs on, in order to talk

and listen to each other. Base station operators can use the UNLATCH button to stop Beltpac conversations, in

order to have uninterrupted communication with the Beltpac users.)

4. IC (Intercom) and ISO (Isolate) Receiver Indicators and Controls

Lights indicate whether Beltpac reception is IC or ISO. Use IC and ISO controls to independently adjust

IC and ISO receive levels. NOTE: This adjustment does not affect Beltpac-to-Beltpac communication.

5. Local Headset Connector, Indicators and Controls

• Adjust the microphone level control, above the TALK button on the front panel, to mid-point. The

level can be readjusted during use, as needed.

• Adjust the receive level by turning on a Beltpac, speaking into the Beltpac headset microphone and

listening through the local headset earpiece while adjusting the VOLUME control on the base station to

the desired level.

• Use the SELECT button to select communication via IC or ISO. Above the SELECT button, the

indicator light will be lit for the selection you made. IC will allow you to communicate via the intercom

channel. ISO will send your audio to Beltpacs and auxiliary output if ISO+ is enabled (See #7 above).

NOTE: If neither 2W nor 4W is on, this will have no effect. It will stay on ISO.

• For open communication, press and release the TALK button quickly to “latch on.” To “latch off,”

press and release the button again quickly.

• For momentary communication, press and hold the TALK button for more than one second. In this

mode, the selected channel will remain open only as long as you are pressing the TALK button.

The TALK light indicates the TALK mode is active via the local headset.

• Use the TALK control knob to adjust the outbound audio level from the local headset microphone.

• Use the VOLUME control knob to adjust the input to the local headset earpiece.
