RF Transmit/Receive Channel Switches

Allows the user to select which of the two RF chan- nels the unit is on. The transmit channel selected, either “A” or “B”, is the frequency of the beltpack’s transmitter.

The receiver channel selected, either “A” or “B”, is the frequency the beltpack’s receiver is at. The fre- quencies are listed on the label which is located un- der the beltpack’s battery pack.

The base station’s transmit frequency must match the beltpack’s receive frequency. Also the base station’s receiver must match the beltpack’s transmit frequency. Typically the base station switches are both set to “A” or both to “B” and the beltpacks are set to match.

RF Transmit Mode Switch

Allows the operator to select two different types of transmitting modes; Push-to-talk or Push-to-transmit. For most operations, place the transmitter switch in the “Push-to-talk" mode.

In the “Push-to-talk” mode the RF transmitter will be on at all times regardless of whether the talk switch is on or off.

In the “Push-to-transmit” mode, the transmitter will be on only when the talk button is activated. The transmitter will be turned off when the talk button is deactivated.

Code Switch (TR-600C Only)

Allows the operator to select over 65,000 cipher codes. The beltpack’s code must match the base sta- tion’s code for audio recovery. Any combination of letters and/or numbers may be selected except 0000. The data is unencrypted when the setting is 0000.
