SCAN
Scan allows each of the channels that has a receive
frequency stored to be automatically monitored for
activity.
BUSYFREQUENCY STOP
The radiotelephone automatically stops scanning when
a signal is detected if Busy Frequency Stop is switched
ON by Menu No. 05. The radiotelephone remains on
the same channel for either a short time or until the
signal drops depending on which Scan Resume method
is selected (see below). The squelch must be adjusted
to the noise threshold point with no signals present for
Busy Frequency Stop to work.
If Busy Frequency Stop is switched OFF by Menu
No. 05, then all channels that contain a receive
frequency are scanned, but the scan never stops on any
channel.
.

the busy channel approximately three seconds later.

SELECTIVE CALLUNIT(OPTIONAL)
After the Dealer installs the optional KPE-1 Selective
Call Unit, you can place calls to other stations by using'
the Microphone keypad to "dial" their unique
Identification code. You can also receive calls from
other stations that have dialed your Identification code.
In addition, Group calls allow you to call and
communicate with a group of stations in your system.
With a single call, you can contact a number of stations
at the same time, and transmit a message that will be
heard by all of these stations. The "*" symbol is used
as a wild card when programming Group codes. For
example, sending the Group code "*0*"
would allow
you to contact all stations that have the number "0" in
the second digit of their Identification codes.
