Manual station search: Slightly press the DOWN or UP key (held for not more than 1 second), and the equipmentwill step once (50kHz per step for FM, and 9kHz per step for AM) towards high frequency or low frequency, andthe corresponding frequency will be displayed on the screen. Manual station search is suitable for searching astation of which signal is weak.
Station Storage: After a station is found, the station can be stored to the preset station storage No. by followings:Press MEMO key, and “MEM” sign and a preset storage No. “CHXX” will flash on the right top corner of thescreen. Press M-DOWN or M-UP key to select one of the storage Nos. from CH10 to CH20, and then press theMEMO key again to store the station found to the storage No..

effect.
“PRIORITY” terminal on the rear panel for microphone features Mute function when a short-circuit signal isinputted. (Except chime signal), other signals can be suppressed by the signal from the four microphones. When“PRIORITY” terminal is shorted, both chime and microphone feature Mute function of the same priority. If thevolume of chime is minimized, microphone signal can be outputted individually. The Mute function can becanceled by canceling the short-circuit signal.
5．Built-in Chime Generator
Chime signal of the equipment can be outputted by short-circuit toggle through “PRIORITY” terminal on therear panel. Short-circuit once, and the chime signal will be outputted once. If another chime signal is desired,cancel the current short-circuit and short the “PRIORITY” terminal again. The output volume of chime can beadjusted by “CHIME VOL” knob. Since chime features overriding function, it is suitable for forced insertion.
