Menu Button
Pressing this button will sequentially select among the following
features, Continuous Tone Coded Squelch System (tc), channel
scan (SCan), button conformation tones (BP) and the keypad
lock (LC). Each successive press of the button will advance
the display to the next feature in order. If no buttons are
pressed for 5 seconds, the unit will return to standby mode and
the display will indicate the current channel. Pressing the PTT
or Monitor button will also return to the standby mode.
Continuous Tone Coded Squelch System (CTCSS)
This feature allows you to ignore transmissions from other
units that are using the same channel. One of 38 privacy
codes may be selected. The same code must also be
selected on those transceivers with which you desire to
communicate. Keep in mind, however, that this feature does
not prevent others from listening to your transmissions.
