1.) Why does my audio drop out?

The source's volume is too low. The internal electronics will shut off within 5 minutes if no/very little volume is detected. The signal level needs to be increased before reaching the transmitter. The transmitter needs a “line-level” signal to work with. This can be accomplished by turning up your source on variable-level outputs, or by amplifying the signal from a fixed-level output. Try increasing it in small increments to prevent overload which results in distortion. Your source component may have a weak output which is causing this.

2.) How do I remove the batteries on the RS110, RS120, RS130, RS140?

Twist off the ear cushions counter-clockwise to locate the battery compartment.

3.) Why won't the charge light stay lit? Why won't my headphones charge?

Try retracting your earcups back inside the headband before placing them on the charging cradle.

4.) Why does the volume go up and down on it's own?

The input volume is too high. To resolve this, turn down your source volume.

5.) Why is the range limited?

Your environment plays a large role in RF reception. Try moving the transmitter a few inches and away from other electrical equipment. Keep in mind that ceiling/wall construction, surrounding buildings, other, congested RF traffic (densely populated areas exhibit this) and weak batteries contribute to shortened range.

6.) Can I use multiple headphones with one transmitter?

Yes! Simply order the add on headset for your system, specified below:

RS100 --- > HDR120 RS110 --- > HDR120 RS115 --- > HDR120 RS120 --- > HDR120 RS130 --- > HDR130 RS140 --- > HDR140

A sole transmitter is not available separately.

7.) I have plugged my transmitter in, however I can still hear my original source through the speakers. Why?

It is also important to note that source volume is dependent on your component. The RS series can connect via the RCA or headphone jacks on your components. Generally speaking, the following occurs when you connect a Sennheiser wireless headphone to your component: connected to the RCA jacks: You can operate volume levels independently. You can also shut off the main speakers via a menu and continue output to the transmitter (newer components). connected to the headphone jack: The speakers will automatically shut off once you plug the jack into the socket. Your volume is now dependent on the level of your component. As stated before, it will depend on your television; the transmitter does not shut anything off or change settings... it's sole purpose is to take whatever audio signal it is given, and send it to the receiver/headphone.

8.) Why do I hear distortion, pops and other noise?

Turn down your source volume and work with your tune control. All wireless products at some point or another will require adjustments because each user's environment is unique (do you have 900 mHz cordless phones in use?) Work with the tune dial (on the headphone) on every frequency that the transmitter offers- moving it slowly, rather than quickly, will often locate the source audio. If you have an auto-tune, try cycplistng a few times through, and/or try a new transmitter channel. Is the transmitter plugged into a working power outlet using the suppplisted power cable? It must be to function. Is your source’s audio output plugged in securely to the transmitter’s audio output jacks? (outputs are generally located on the back of the source, not the front, which are generally inputs) Have your batteries been charged the initial 24 hours? Is the battery/batteries securely plugged in and facing the correct direction? Have you tried your headphones on another source of audio? Are you using the correct batteries (BA151 for RS4x, 6x, 8x, Ni-MH rechargeables for RS1xx series)? Have you tried a new rechargeable battery/batteries? Have you tuned your headphone and tried all available channels?
