4.11.4 SCAN HOLD TIME
When a message is received or transmitted while
scanning, there is a delay before scanning resumes.
The delay after receiving a call prevents another
message from being received before a response can be
made. The delay after transmitting a call ensures that a
response is heard instead of another message occurring
on some other channel.

Separate delay times are programmable for radio
wide and standard scanning. With radio wide and
conventional standard scanning, delays of 0-7.5
seconds are programmable in 0.5-second steps. With
SMARTNET/SmartZone and P25 Trunked standard
scanning, a scan delay of 2-10 seconds can be
programmed in 0.5-second steps.

4.11.5 TRANSMITTING IN THE SCAN MODE
Standard Scan Mode
When the transmitter is keyed while scanning is
enabled, the transmission may occur on various
channels as follows.
channels as follows.
Conventional Operation - Transmissions can be
programmed to always occur on the priority,
selected, or receive channel (if applicable). Refer to
Section 5.11 for more information.

Operation - If scanning is halted to receive a
message, programming determines if transmis-
sions occur on the selected or active channel.
Transmissions at other times occur on the selected
channel.

4.11.6 NUISANCE CHANNEL DELETE
With standard scanning, channels can be tempo-
rarily deleted from the scan list, for example, if
messages become annoying. This feature is not avail-
able with radio wide scanning. Channels can also be
permanently added or deleted from a scan list as
described in the next sections. Proceed as follows to
temporarily delete a channel:

NOTE: The selected channel and also conventional
priority channels cannot be deleted from the scan list.

4.12 SCAN LISTS
4.12.1 STANDARD MODE SCAN LISTS
General
NOTE: The selected channel is always scanned.
A scan list is simply the channels that are scanned
when scanning is enabled. With all operating modes,
as many standard scan lists as are required can usually
be programmed (up to 256). The only limitation is the
available memory. Each list can include up to 256
