Antenna Connection
The beltpack comes with two detachable, screw type, ¼ wave
antennas. To attach the two antennas, screw into the recepta-
cles at the bottom of the beltpack. The color dot on the screw
end of the antenna must match the color dot on antenna recep-
tacle. The longest antenna is the receiver antenna. It screws
into the left receptacle if the beltpack is laying flat with the
battery compartment face up and the antenna receptacles fac-
ing you. The other antenna is the transmit antenna. New an-
tennas can be ordered if desired, see the “Accessories” section.
Transmit mode
The rear panel located transmit switch has the following two
modes:
Push-to-Talk (PT TALK) – Recommended position –
The transmitter is always on. No audio is sent unless the
talk switch is pressed.
Push-to-Transmit (PT TX) – The transmitter and audio
paths are off except when the talk switch is pressed.

Insert the headset plug into the XLR connector. See the head-
set pinout in the “WTR-670 beltpack controls and connec-
tions” section if this is not a Clear-Com ® headset. A dynamic
