By default, your scanner displays the stored alphanumeric text tag when receiving a trunked voice call. You
can toggle the display to show the text tag or the talkgroup ID code by pressing TEXT while the scanner is
stopped on a trunked talkgroup call.
TRUNKED DELAY FUNCTION
The trunking ID delay is set separately from the channel delay on a per channel storage bank basis.
Trunking ID delay specifies the amount of time the scanner dwells on the control channel looking for reply
traffic on the previous talkgroup before resuming scan operation. Customizing the trunked ID delay may be
useful if you are missing a lot of reply traffic on a particular system. We recommend starting with the default
value of 2.0 seconds.
1. While in the desired ID list, press FUNC, and then ./DELAY.
2. Press ^ or v to select None, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, or 4.0 seconds.
3. Press ENT.
Hints:
. Most Motorola trunking systems include a “hang time” where the channel remains assigned to a talkgroup
for a short period after the user unkeys their microphone. This hang time is typically 1.5 seconds but can
vary among different systems. The scanner’s trunked delay function begins after this hang time expires.
Therefore, the total amount of delay present after a user unkeys their microphone equals the trunking
system hang time, plus any trunked ID delay that you have programmed into the scanner. For example, if
you wish to wait a total of two seconds for a reply trunked call, and the system you are monitoring is using
1.5 seconds of hang time, you should set the trunked delay for that system to 0.5 seconds. EDACS
systems do not employ hang time.
. Conventional channel delay is fixed at 2 seconds and is controlled independently of trunked ID delay.
Refer to “Using the Delay Function” on Page XX for more information.
CLEARING TALKGROUP IDS
You can clear IDs from the ID list to make room for new IDs.
1. Press PROG and then TRUNK.
2. Press FUNC, ^ or v to select an ID memory.
3. Press FUNC and then CLEAR to clear the contents of the selected ID.
Clearing All Talkgroup IDs in One Bank
You can clear all talkgroup IDs within a bank. This lets you quickly delete all talkgroup IDs from a bank if
