channels. If a single channel has been
preprogrammed, then pressing the key will
select the preprogrammed channel. If the
dealer has preprogrammed two channels,
then pressing the key will alternate between
the two preprogrammed channels. The
display will show the channel selected.
Talk Around This is an alternate action key that selects
between talkaround mode and repeater
mode. In repeater mode, the radios talk
directly to another radio. In repeater mode,
the radios talk to the repeater and the
repeater in turn talks to another radio.
Repeater mode extends the range of the
radios. Talkaround mode is useful when the
repeater is out of range or the signal
strength of the repeater is not sufficient to
penetrate inside a building such as when
you have a firefighting incident.
For this key to work, the transmit and
receive frequencies must be different and
the key must not be disabled for the
channel you are using. When the key is
pressed and it goes in the talk around
mode, the display will show “Talkarnd
Mode” for a few seconds. When the key is
pressed and it goes in the repeater mode,
the display will show “Repeater Mode” for
a few seconds.
VOX This is an alternative action key that
enables or disables VOX. When VOX is
enabled, the user only has to speak to
transmit. The PTT switch in this mode does
not have to be pressed. VOX is useful
when the operator of the radio cannot free
his hands to use the radio as what might
happen if you are driving. When the VOX
mode is enabled, the second line of the
display will show “Vox”.
Monitor Momentary/Call Cancel Pressing the Monitor Momentary/Call
Cancel key allows monitoring the channel
for any voice traffic. The incoming signal
has to have the required squelch level
before anything can be heard. Releasing the
switch puts in back in the normal mode.
