Transmitting; Low-Battery Alert - Motorola JT 1000 User Manual

11 Basic Radio Operation (cont.)

Transmitting

1. Turn the radio on and set the channel selector
to the desired channel position.
2. Listen for a transmission and adjust the
volume control to a comfortable listening level.
If no transmission is heard, press side button

background noise to a comfortable listening
level.
3. Do not interrupt another user. If the channel

c h a n n e l i s n o t i n u s e b y m o m e n t a r i l y
depressing the monitor button to listen for
activity, or check for the LED to be flashing
red.
4. To transmit, hold the radio in a ver tical
position with the microphone two to three
inches away from the lips. When the channel
is clear, press and hold the PTT on the side of
the radio and speak slowly and clearly into the
microphone area. The LED will be red while in
the transmit mode. When your transmission is
completed, release the PTT to listen.
Note: Avoid blocking the noise-cancelling port
while transmitting to take full advantage of the
noise-cancelling feature.

Low-Battery Alert

While in transmit mode, the LED will blink red
if the battery falls below a low voltage level (Radio
Service Software programmable, blinking LED is
factory default). The radio can be programmed via
Radio Service Software to emit a double-chirp tone
to indicate a low-battery condition. If a low-battery
condition exists, the tone will be emitted when the
PTT is released in transmit mode, and when the
low-battery condition is detected in receive mode.
Also, in the transmit and receive modes, when
a low-voltage level is detected, the LCD battery-
status annunciator will blink.
Note: If the JT 1000 radio is using an NTN7319
Alkaline battery pack, the low-battery alert point is
automatically reconfigured.
