RADIO-WIDE FEATURES
22
•
Enable Radio Wide Scanning using the Radio Wide
Scan option switch or menu parameter. As with
standard scanning, radio wide scanning is indicated
when the
icon is displayed.
•
To turn radio wide scanning off, press the Radio
Wide Scan option switch again or select “Off” in the
menu. Scanning is disabled when the
icon is no
longer displayed.
•
If the zone or channel is changed while radio wide
scanning, scanning continues normally.
4.8.4 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.
4.8.5 TRANSMITTING IN THE SCAN MODE
When the transmitter is keyed while scanning is
enabled, the transmission may occur on various
channels as follows.
Conventional Operation - Transmissions can be
programmed to occur on the priority, selected, or
receive channel. Refer to Section 5.11 for more
information.
SMARTNET/SmartZone/P25 Trunked Operation - If
scanning is halted to receive a message, program-
ming determines if transmissions occur on the
selected or active channel. Transmissions at other
times occur on the selected channel.
4.8.6 NUISANCE CHANNEL ADD/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 Section 4.9.5. Proceed as follows to
temporarily delete a nuisance channel:
NOTE: The selected channel and also priority chan-
nels cannot be deleted from the scan list.
1. While receiving a message on the channel to be
deleted, press and hold the Scan option switch until
a tone sounds (about 1 second).
2. The channel is then deleted and scanning of the
remaining channels in the scan list resumes.
3. Deleted channels are added back into the scan list if
any of the following occur:
•
Scanning is turned off and then on again using the
Scan option switch or menu parameter.
•
Transceiver power is turned off and then on again.
•
The selected channel is changed.
4.9 SCAN LISTS
4.9.1 STANDARD MODE SCAN LISTS
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 scan list can include up to 256
channels/talk groups (or optionally up to 512). Refer
to Sections 4.9.4 and 4.9.5 which follow for informa-
tion on selecting and editing standard scan lists.
4.9.2 RADIO WIDE SCAN LIST
With radio wide scanning, there is only one scan
list available regardless of the type of channel selected,
and it is not user programmable. This scan list can
contain up to 16 channels of any type. For example, it
could include six conventional channels and ten
SMARTNET/SmartZone channels.
