■ Scan types
Scanning searches for signals automatically and makes it
easier to locate new stations for contact or listening purposes.
There are 3 scan types and 4 resume conditions to suit your
operating needs.
FULL SCAN 
(p. 38)
Repeatedly scans all frequen-
cies over the entire band.
Used as the simplest scan
without any preliminary set-
tings necessary.

output frequencies, etc. 3
pairs of scan edges are avail-
able.
