Locking/Unlocking a Site
It is sometimes desirable to stay on the current site regardless of
signal level. To lock the radio on the current site so that it does not search
for another, press the Site Lock option switch (if programmed). The
display then momentarily indicates “LOCK x” to indicate that the current
site is locked (“x” is the current site number). To unlock the site, press the
Lock switch again and “UNLOCK” is momentarily displayed.
When locked on a site, it is still possible to search for a different site
using the site search function described in the preceding section. When a
new site is found, the radio is then locked on that site.
