When the Active frequency receives a signal, the unit will switch automatically to the Ac-
tive 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. Monitor-
ing is not canceled by switching to Nav mode.
Saving a Com Channel
You can save the Standby frequency and give it a name of up to four characters. A com-
bination of up to 250 Com and Nav frequencies may be saved. After 250 Nav and Com
frequencies are saved, you will get a “Database Full” message. You will have to remove fre-
quencies before any more can be saved.
A frequency type can also be assigned along with the saved selection. Types available in-
clude: Tower (TWR), Ground Control (GND), ATIS (ATS), Air Traffic Frequency (ATF), Ap-
proach (APP), Arrival (ARR), Automated Weather Station (AWS), Clearance (CLR), Common
