• To turn radio wide scanning OFF, press the RWS option switch again and “RW SCN
OFF” is briefly displayed and (Standard Control Head) or (Lightning Control
Head) with R is no longer displayed.
• If the zone or channel is changed while radio wide scanning, scanning continues
normally.
4.12.3 Scan Hold Time
When traffic is received or transmitted while scanning, there is a delay before scanning
resumes. The delay after receiving a call prevents other traffic from being received before
a response can be made. The delay after transmitting a call ensures that a response is heard
and prevents other traffic from occurring on some other channel.
Separate delay times are programmable for radio wide and priority scanning. With radio
wide scanning, delays of 2 to 7.5 seconds can be programmed. With priority scanning,
delays of 0 to 7.5 seconds can be programmed. With SMARTNET/SmartZone and P25
Trunking scanning, scan delays of 0 to 8 seconds can be programmed.
4.12.4 Transmitting in the Scan Mode
Priority 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 always occur on
the priority, selected, or receive channel (if applicable). Refer to Section 5.10 for
more information.
SMARTNET/SmartZone/P25 Trunking Operation - If scanning is halted to
receive a message, programming determines if transmissions occur on the selected or
active channel. Transmissions at other times occur on the selected channel.
Radio Wide Scan Mode - The radio can be programmed to transmit on the selected or
active channel similar to SMARTNET/SmartZone and P25 trunking operation just
described.
