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
REMOTE IS USED TO TURN THE POWER BACK ON.
