DESCRIPTION

FRONT PANEL

Station Call

M1 - M6: Directly accesses the preprogrammed station within the selected frequency band.

Band: Advances through the 2 AM and 3 FM bands.

A/PS: Advances through the station presets within the selected frequency band.

Ster/Mon: Selects between Stereo and Mono operation.

MUTE: Mutes all outputs.

Scan/Up: Increases the frequencies until a station strong enough to lock onto is reached. That station is played for approximately five seconds then scanning begins again. Scanning is continuous until a front panel button is pressed. The station the RS79 stops at will remain.

Seek/Up: Increases the frequencies until a station strong enough to lock onto is reached. That station will remain.

Tune +: Increases the tuner frequency by .1 MHz each time it is pressed.

Tune -: Decreases the tuner frequency by .1 MHz each time it is pressed.

LCD DISPLAY

A:Band indicator and number. There are three banks of FM and two banks of AM presets. NOTE: If the rear panel Frequency Select switch is set for 9kHz, the band will indicate MW 1 and MW2 instead of AM1 and AM2.

B:Stereo indicator. Indicates a locked signal and stereo operation. If this light is out, the unit is operating in mono or the station is weak.

C:Lock indicator - if lit the RS79b is locked onto a station.

D:Station frequency indicator

E:Indicates whether the station frequency is AM (KHz), or FM (MHz)

F:Preset number - 1 - 6.

G:IR - Infrared Remote sensor.

• Power Switch: Applies power to the RS79b.

IMPORTANT NOTICE: IF THE POWER IS TURNED OFF BY THE REMOTE, THIS FRONT PANEL POWER SWITCH IS INOPERABLE UNTIL THE

5

REMOTE IS USED TO TURN THE POWER BACK ON.
