REMOTE Remote Operation: The included Infrared Remote provides a way to control the RS81B at a distance from the unit. It must be located in the “line-of-sight”. Remote Description: -BAND: Switch for AM or FM -Press “ BAND ” to select FM 1,FM 2, or AM frequencies. -Press “TUN+ / TUN-” to select stations. Press and hold for over 2 seconds enters into automatic scan searching. After a station is received, it will stop automatically and start to play the station.

OPERATION RADIO TUNING RANGE FM 87.5 MHz – 108 MHz AM 530 KHz – 1710 KHz (US) / AM 522 KHz – 1611 KHz (Europe) - The AM tuning steps from 9kHz (Europe) to 10kHz (US) have been preset by the factory. The RS81B 9kHz to 10kHz AM can not be changed. Connect the RS81B to a properly grounded AC outlet. Connect the Left and Right outputs to a mixer, amplifier, or other audio device. FM Antenna: For an Indoor FM antenna Connect the wire FM antenna to its corresponding input on the rear panel of the RS81B.
PAGE 6
OPERATION RDS (Radio Display System) FUNCTION RDS is a data stream of information sent out by certain FM radio stations along with the actual program. To utilize this feature, you must first be tuned to a station that carries RDS signal. NOTE: Allow 30 - 60 seconds for the data to download. Not all stations that carry the RDS data carry all functions of RDS (ie; some do not carry the “clock” or “text” data).
PAGE 7
OPERATION Sleep function: -Press “ SLEEP “ -Maximum set up time is 90 minutes. Increase by 10 minutes for every press, this is indicated by the LCD display. Sleep set up is cancelled on final press (LCD shows “00”). -When you reach the pre-set time limit, the tuner will automatically stop playing and go into stand by mode. -If want to reactivate (power on) the RS81B after it goes into sleep mode, turn off the main power switch and then turn the power switch on.
