EXTERNAL CONTROLS (Refer To Figure 6)
Volume OFF/ON Control: This thumbwheel
control serves as both an off/on switch and as a
volume control.
Low Battery and Overmodulation Indicator
LED:
Low Battery Indicatorœ: Part of the bat-
tery check circuit. When the power switch 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
continuously and a bad or unusable battery
will not cause any illumination at all.
Overmodulation Indicator: Uses the same
LED as the low battery indicator. During the
talk mode, if the microphone gain is too
high, the LED will illuminate when talking.
Push-To-Talk/Lock-To-Talk Switch: For
Model TR-200, this switch enables the talk
function. For Model TR-200P, this switch en-
ables the transmit and audio function and oth-
erwise operates as described for TR-200.
Talk LED Indicator: (Labeled "talk") Will be
illuminated whenever the talk function on the
TR-200 or transmit function on the TR-200P is
enabled.
