Beyond the Basics
direct entry id hold mode
Enter the ID you want to receive by using 1 through 9, 0 (or ./
CLR) and press , and you can listen to a specifi c ID (without
d
storing ID to the list).
ID search mode
Once you have programmed all the frequencies for a
trunked system, search will let you immediately start hearing
transmissions. When in the trunking mode, press SRCH and
the scanner begins to fi nd any active IDs. When the scanner
fi nds the control channel data, the scanner begins trunking,
and -- --- appears on the display until the scanner fi nds an ID.
If the scanner does not fi nd an ID in about 1 second, it moves
on to conventional channels in the same bank or to the next
active bank. This may happen a few times (if the signal is
weak) when the scanner comes around to that bank again.
The scanner will recognize the control channel was lost when
no ID can be found, even if the scanner tries ten times.
The scanner will begin to search for the control data channel.
If it fi nds any non-locked-out IDs, you will hear it. You will
then hear any replies that follow within the specifi ed periods.
After that, the scanner will move on and not continuously
search the system for additional IDs (on busy systems you
would never leave the system if this were the case). If you
press while monitoring an ID, the radio will check if any
e
other IDs are active (it will disregard the ID you just left), and
none are active, the scanner resumes searching.
ID search hold mode
If you hear an interesting ID during search mode and want to
continue listening to it, press HOLD/RESUME. HOLD and the
ID appear.
