UP and DOWN Buttons:
If these buttons are pressed before pressing the Lock/function button, a single press
will display the current volume setting and subsequent presses will change the volume
setting up or down.
Important: If a speaker/microphone or earphone is used, check the volume setting
before connecting it to the earphone jack. Be sure to set the volume low
at first, and then raise it to a comfortable level.
Lock/Function Button:
The Lock button allows the user to eliminate the possibility of accidentally changing the
transceiver’s selectable functions. Pressing and holding this button for two seconds will
activate the lock function. “LOCK” will be displayed in the lower right of the display,
indicating that the settings are locked in. While in the lock mode, it is still possible to
adjust the volume, however other settings will be fixed. To unlock the transceiver simply,
press and hold the lock button for 2 seconds. While the unit is unlocked, you may
change any of the adjustable features by following the instructions that follow.
PTT (Push To Talk) Button:
Pressing and holding this button will allow you to speak to any transceiver that is set to
the same channel and privacy code setting as yours. Hold the transceiver approximately
3 to 5 inches from your face as you speak. After you have finished speaking, release
the PTT button to allow the reception of incoming signals. It is not possible to transmit
and receive at the same time. “ON AIR” will show on the left side of the display and the
red LED to the left of the display will illuminate while the PTT button is pressed.
Low Battery Warning:
“BATT LOW” will show in the upper right hand corner of the display as a warning of low
battery voltage. As the batteries become weak only the word “ON” instead of “ON AIR”
will show on the display when the PTT button is pressed.
Signal Strength Indicator (SSI):
The six dashed lines ------ on the lower left of the display indicate the strength of incoming
signals. Six lines represents a strong signal. One line indicates a weak signal. While
receiving a signal, one to six lines will be displayed indicating the strength of the signal.
While pressing the PTT button the signal strength indicator represents the strength of
the signal being transmitted.
