The function selected by pressing and holding the DISP
button more than 2 seconds (but less than 4 seconds) can
be customized by dealer programming and your network
requirements. A brief explanation of available functions
is provided below. However, contact your dealer for de-
tails on their use and operation.
Low Transmit Power
This reduces the power output of your radio to ap-
proximately one watt to conserve battery life, and when
full power is not needed to maintain reliable communica-
tions. “
LO ” will be displayed at the upper right corner
when enabled.
Alpha Tag
This displays an alpha-numeric channel name, usual-
ly describing the channel, rather than merely displaying
a channel number. These may be programmed to assist
you in recognizing channels by name, rather than by mem-
orizing channel numbers and their assignments.
Talk Around
This feature enables simplex operation on semi-duplex
channels: the transmit frequency becomes the same as the
receive frequency (regardless of any programmed offset
for the channel).
Note : This feature has no effect on simplex channels.
