Features
Volume ON/OFF Control: This thumbwheel control serves as both an on/off
switch and as a volume control. The transceiver is turned off when the control is in
the extreme counterclockwise position, when viewed from the front, and the vol-
ume is loudest when the control is in the extreme clockwise position.
Low Battery and Over Modulation Indicator LED: (labeled “bat/ovmod”)
Low Battery Indicator: Part of the battery check circuit. When the volume
ON/OFF Control is placed in the “ON” position the LED will flash one time if
the battery is good. A poor battery will cause the LED to illuminate continu-
ously and a bad or unusable battery will not cause any illumination at all.
Over Modulation Indicator: Uses the same LED as the low battery indicator.
During the transmit mode if microphone gain is too high the LED will illumi-
nate when talking. Adjust microphone gain.
