disabled on a channel, that channel will be skipped
during MR/CH scans. A channel’s scan status will

Squelch Level (SQL): Menu 40
The squelch circuit allows you to only hear desired
signals. If a strong enough signal is not present, the
squelch circuit is closed, and you will hear no
background noise. Higher levels of the Squelch level
setting require stronger signals to open the squelch
circuit. Set the squelch level to one appropriate to the
amount of RF noise in your environment. A squelch
setting that is too high may cause you to miss
receiving a weaker signal, while too low a setting may
cause you to hear more noise than you might want.
Set the Squelch Level using Menu 40. There are nine
levels of squelch setting; the default level is 2.
Step (Step): Menu 41
Step is the value in which the operating frequency
increases or decreases with presses of the “Up”,
“Down”, or “CHA+/CHA-“ keys in VFO mode.
Select the Step in Menu 41. Valid step sizes are 2.5, 5,
6.25, 10, 12.5, and 25 KHz. The default is 25 KHz.
