WIRELESS RS 80-7 English WIRELESS RS 80 Thank you for choosing Sennheiser! Over half a century of accumulated expertise in the desi gn and manufacture of high-quality electro-acoustic equipment have made Sennheiser a world-leadin g company in this field. We have designed this product to give you reliable operation over many years. Please take a few moments to read these instructions carefull y, as we want you to en joy your new Sennheiser product quickly and to the full. SYSTEM COMPONENTS AND CONNECTIONS Before proceeding, please check and make sure the s ystem components shown are all present and correct (see illustration inside cover page). Establish the necessar y connections. Char ge the accupack for 24 hours before you use it for the first time! (please refer to the section Charging the Accu pack) WHERE TO PLACE THE TRANSMITTER Choose a suitable place near your hi-fi system or TV set. Do not place the transmitter close to metal objects such as shelf bars, reinforced concrete walls, etc. The transmitter features a convenient automatic on/ off function, i.e. it is switched on or off via the audio si gnal from the sound source. The transmitter’s char ging function is independent of the automatic on/off function. Accupacks can alwa ys be recharged when the transmitter is connected to the mains. SWITCHING THE HEADPHONE RECEIVER ON The O N /O FF switch is on the right earpiece. SWITCHING THE HEADPHONE RECEIVER OFF Make sure to switch off the head phones after each use and store the head phones in the transmitter’s char ging compartment to avoid discharging the accu pack. Bild mit Uhr Bild mit Aufstellort einfügen Bild mit EIN / AUS am Hörer einfügen WIRELESS RS 80-8 English ADJUSTING THE VOLUME Set the volume of your sound source to a medium value. With some devices, the volume for the head phone output can be regulated separately. Use the V OLUME control on the right earpiece to ad just the headphones ́ volume. ADJUSTING THE RECEIVER CHANNEL Turn the T UNE control on the earpiece until you can hear the audio si gnal loud and clear. CHANGING THE TRANSMISSION CHANNEL To avoid interference caused b y the simultaneous o peration of several transmitters, select a different channel on each transmitter. De pending on the s ystem variant, two or three switchable transmission channels are available. To select a channel, press the C HANNEL button until the desired LED or LED combination li ghts up: LED 1channel 1 active LED 2channel 2 active LED 1 and 2channel 3 active (except 863 MHz version) COMPLETE FREEDOM OF MOVEMENT It is not necessar y that transmitter and headphone receiver are in a direct line of si ght, so you can move around freel y in the home or outside in the garden. One transmitter can be used to transmit to several receivers on the same fre quency. Additional head phones with the designation HDR 80 are available from your specialist dealer. Please make sure to choose head phones with the same fre quency range as the transmitter you are using (see type plate on the bottom of the transmitter). Doppel-Bild mit Lautst.

The Sennheiser logo on the headband must be readable lookin g from the front - see dia gram. The charging contacts are on the RH ear piece of the headphones - these are placed on the corres ponding contacts in the LH indentation of the transmitter, the one next to the “char ge” light). The red LED on the transmitter must li ght up to show charging is taking place. Alwa ys store the headphones on the transmitter to ensure that they are fully char ged when they are needed. The headphones are automatically switched off by the char ging process. BA 151 SPARE ACCUPACK When the head phones’ accupack is going flat (noise, interference and distortion are sure si gns of a flat accupack), recharge the accupack. After an initial charging of 24 hours, the normal char ging time is 14 hours. A fully charged accupack has an o perating time of approx. four hours. Place the discharged accupack in the charging com partment at the back of the transmitter and use the spare accupack in the meantime. Additional BA 151 s pare accupacks can be charged via the L 151-2 charger (available from your specialist dealer). Before dis posing of an old and exhausted accupack, make sure that it is totally dischar ged by using it until the device switches off. To protect the environment, only dis pose of totally exhausted accupacks. HiD yn plus ® This device is e quipped with HiDyn plus ® , Sennheiser ́s noise reduction system that reduces noise and interference in wireless transmission s ystems. ADDITIONAL INFORMATION The audio transmission technolo gy used with this device is basically that of a radio. Accordin g to today’s scientific knowledge, the radio waves emitted by this device are not harmful to humans or animals.

FCC ID: DMORS99SA Federal Communications Commission 7435 Oakland Mills Road Columbia, MD 21045 Authority to Act as Agent to the Federal Communications Commission On our behalf, I appoint Cetecom to act as agent in the preparation of this application for equipment authorization to the Federal Communications Commission. I certify that submitted Exhibits properly describe the device or system for which equipment authorization is sought. I also certify that each unit manufactured, imported or marketed, as defined in the Commission’s regulations will have affixed to it a label identical to that submitted for approval with this application. Dated this 15th day of December, 1999 Agency agreement expiration date: June 15, 2000 By: Name:Uwe Sattler Title:Technical Director Telephone:860-434-9190 Ext. 128 Applicant:Sennheiser Electronic Corp.

SENNHEISER APPLICATION FOR WIRELESS MICROPHONE SYSTEM Application filed for certification under Section 15.249 of the FCC Rules The Sennheiser application is requesting certification of a product family consisting of Models RS 30, RS 40, RS 60, and RS 80. They use identical transmitter output circuitry and differ only in the features that are available from the receiver decoder circuitry, such as stereo capability, etc. Test report for the Mdls. 30, 40, and 80 have been filed showing compliance with the applicable limits. The test report for the Mdl. 60 transmission file was corrupted during transmission and was not available for filing. Due to the similarity of the units (all models use the same transmitter output circuits), it does not appear to be necessary to file the report for the Mdl. 60. However, if the reviewer judges that it is needed, I will be pleased to forward a copy to you. Phil Inglis Agent for Cetecom/Sennheiser 1/8/99

REVISED THAT LABEL WILL BE ATTACHED TO THE TRANSMITTER PER FCC REQUEST: Below is the drawing of the revised FCC ID label. This Label will be located on the bottom of the transmitter unit in the location as shown on the label location photo. FCC ID: DMORS99SA This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Sennheiser will use a label with the above language to satisfy the requirements of Section 15.19. Phillip Inglis
