Low Battery Alert

The "BATT" indicator in the LCD continuously flashes

whenever the radio has a low battery condition (in receive

or transmit mode).

A low battery condition is also indicated by three low-

pitched beeps, repeated every two minutes.

Display Backlight

The LCD has a backlight which is activated when the Toggle Light/Enter Button is

pressed. The LCD backlight turns off 5 seconds after the last user activity or, if

Toggle Light/Enter Button is pressed, the backlight turns off immediately (pressing

Toggle Light/ Enter Button will always toggle the status of the backlight).

PTT ID

If programmed, the radio transmits a DTMF identification code (unit ID), indicating

which portable is in operation.

During a conversation, the code is normally sent only on the initial PTT press

(unless PTT ID has been disabled). The 'TX' indicator lights for the duration of the

PTT ID. If there is no PTT or receive activity for 7 seconds, or if you change the

channel (or scan resumes), the PTT ID is once again transmitted on the next PTT

press.

NOTE: PTT ID can be enabled/disabled by pressing and holding

pressing the button you will hear a beep; hold the button down until you hear a

second beep, indicating that the PTT ID status has been changed, then release the

button. When PTT ID is disabled the 'dot' indicator flashes on the display.

To Transmit

Depending on the mode of operation, select the

desired channel (refer to the next section for details on

selecting a channel).

Do not interrupt another user. If the selected Channel

is programmed to receive PL, press and hold the

Monitor Button to enter monitor mode and listen for

channel activity. The channel must be clear before

transmitting.

Press PTT.

The "Tx" indicator lights up whenever radio transmits,

and goes off when PTT is released.

Hold radio upright while speaking clearly into the microphone.
