■Preparation
• Channels
For programmed scan: Program scan edge frequen- cies into scan edge memory channels 1A and 1B (p. 34).
For memory scan: Program 2 or more memory chan- nels except scan edge memory channels.
For memory select scan: Designate 2 or more memo- ry channels as select memory
For priority watch: Program 1 memory channel to be watched.
• Scan resume ON/OFF
You can select the scan to resume or cancel when detecting a signal, in initial set mode, item 21. Scan resume ON/OFF must be set before operating a scan. See p. 53 for ON/OFF setting and scan resume condi- tion details.
• Scan speed
Scan speed can be selected from 2 levels, high or low, in initial set mode. See p. 47 for details.
