The radio scans for voice activity by cycling through the channel/group
sequence specified in the scan list for the current channel / group. Your
radio can support up to 250 scan lists, with a maximum of 16 members
in a list. Each scan list supports a mixture of both analog and digital
entries. You can add, delete, or prioritize channels by editing the scan
lists.

Scan Instructions and Methods
When a scan is initiated, your radio cycles through the programmed
scan list for the current channel looking for voice activity. The LED
blinks red and you see the Scan icon on the display.
There are two ways of initiating scan:
• Manual Scan:
Initiate scan manually using the programmed by your
RCA Communications Systems dealer Scan ON/OFF side button or
menu function. When scan is initiated, radio will detect all channels /
groups on the programmed scan list.
• Auto Scan:
Your radio automatically starts scanning when you select
a channel / group that has Auto Scan enabled.
Responding to a Scan
During scanning, your radio stops on any channel / group where activity
is detected. After the transmission is over the radio remains on the
active channel for a programmed time period known as “hang time”.
1. Press the PTT button during hang time to respond to the call. The
LED lights up red.
2. Release PTT button to listen.
Note:
If you do not respond within the hang time period, the radio
continues scanning other channels / groups.
