nondirectional beacons and AM broadcast stations for navigation. This mode
activates the bearing pointer. The bearing pointer will point in the direction of the

audio reception clarity and is normally used for station identification.

The Frequency Selection Keypad is used to select the system operating
frequency. The keypad consists of a row of numbered buttons from 0 to 9,
located along the bottom of the RCR-650D Receiver. Frequencies in the
megahertz and kilohertz range may be selected.

The power control is used to turn the receiver on and off. Momentarily
depressing the PWR button will turn the receiver on and also initiate a self test.

If the PWR button is pressed for longer than 3 seconds the
receiver will immediately shut off.
