Frequency Monitoring The Frequency Monitoring function allows you to listen to the Standby frequency, while monitoring the Active frequency for activity. Press the MON button to listen to the standby frequency. A small "m" is displayed in front of the Standby frequency. When the Active frequency receives a signal, the unit will switch automatically to the Active frequency and then switch back when activity ceases. An arrow (< or >) will point to the frequency that you are currently listening to. A slight clicking sound occurs when the radio is checking the Active frequency for activity. The Monitor function is deactivated when you press MON. Recalling a Frequency The SL40 can access several areas of stored frequencies. The SL40 can also receive airport frequencies if connected to certain GPS receivers. Remote (REM) The Remote function will allow the SL40 to access the airport frequency database in an GPS receiver. Press RCL to view the Remote (REM) frequencies. Then, turn the Small, inner knob to display the available frequencies. The waypoint type and frequency are displayed. If not connected to an GPS, or the list is not received, the list will not be available.
