front of the Standby frequency.

When the Active frequency receives a signal, the unit will
switch automatically to the Active frequency. The Active
frequency quality is not affected. The Frequency Monitor
function is turned off when you flip/flop frequencies,
recall a frequency, or press
COM
again. Monitoring is not
canceled by switching to Nav mode.
Saving a Comm channel
You can save the Standby frequency and give it a name of
up to four characters. A combination of up to 250 Comm
and Nav frequencies may be saved. After 250 Nav and
Comm frequencies are saved, you will get a “Database
Full” message. You will have to remove frequencies before
any more can be saved.
A frequency type can also be assigned along with the
saved selection. Types available include: Tower (TWR),
Ground Control (GND), ATIS (ATS), Air Traffic
Frequency (ATF), Approach (APP), Arrival (ARR),
Automated Weather Station (AWS), Clearance (CLR),
Common Traffic Advisory Frequency (CTF), Departure
Control (DEP), Flight Service Station (FSS), Remote
Flight Service Station (RFS), Unicom (UNI), and
Mandatory Frequency (MF).
