PROGRAMMING
4-11
November 1998
Part No. 001-7600-001
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
Timer
This sets the scan resume delay in seconds. This is the time that elapses before scanning resumes after a
message is received.
PWR ON
Scan
If this function is programmed “On”, scanning starts automatically when transceiver power is turned on. The
“Hanger Action” parameter in Table 4-2 should 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
Call
The parameter is displayed only in the PMR (European) mode, and is used with the 5-tone option. If “On” is
programmed, pressing the CALL key (1) starts scanning, (2) detects a non-busy channel, and (3) transmits the
5-tone codes.
