Parameter

Description

 

 

Stop Timer

When Mode 2 or 3 above is programmed (priority scanning), this sets how often in seconds the priority channel

 

is checked while receiving a message on some other channel.

 

 

Resume

This sets the scan resume delay in seconds. This is the time that elapses before scanning resumes after a

Timer

message is received.

 

 

PWR ON

If this function is programmed “On”, scanning starts automatically when transceiver power is turned on. The

Scan

“Hanger Action” parameter in Table 4-2should also be programmed for “Scan” if power-on scan is used. If

 

scanning halts to transmit a message, the timer selected for Auto Reset parameter in the channel screen (see

 

Table 4-1)determines the delay before scanning resumes. See also Scan A/B function in Key Assign screen

 

(Table 4-2), “Scan” column in 2-Tone Code CH screen (Table 4-6),“Timer A/B” in Common screen

 

(Table 4-7), and “Fast/Slow Scan Timer” in Expert screen (Table 4-8).

 

 

Auto CH

The parameter is displayed only in the PMR (European) mode, and is used with the 5-tone option. If “On” is

Call

programmed, pressing the CALL key (1) starts scanning, (2) detects a non-busy channel, and (3) transmits the

 

5-tone codes.
