Introduction

Congratulations on your purchase of the Sharper Image TV Wireless Headphones. Thanks to the latest FM Wireless technology, you will soon be enjoying great audio quality with complete freedom of movement. Please read this guide to install and use the equipment properly, and keep it for future reference.

Important

Before using the TV Wireless Headphones for the first time, please ensure that the batteries are fully charged for about 16 hours. This will guarantee a longer operating lifetime of the batteries.

General Information

Function and Capability

1. RF/FM wireless transmission

   The transmitter sends the stereo audio signal from your audio or video source to the headphones without wires. The headphones receive the signals through walls, doors and windows. The headphones use high radio frequency as the signal carrier, ensuring clear and crisp reception. Multiple headphones can be used at the same time with a single transmitter.

2. Automatic rechargeable system

   The transmitter automatically recharges the rechargeable batteries in the headphones. Simply place the headphones on the transmitter with the recharging contact on the transmitter and headphones connected. The green LED ? will light up during recharging. After the batteries are fully charged, the green LED ? light will turn off.

3. Volume control

   A volume controller is located on the left headphone. Simply adjust the knob for desired volume level.

4. Applications

   The RF/FM Wireless Stereo Headphone System is compatible with TVs, stereo systems, VCRs, DVD players, CD players, MP3 players, iPods, computers and all other audio and video equipment.

Troubleshooting

Question: When there is no sound

Remedy:

1. The batteries in the headphones are running low. Simply place the Headphones on the transmitter to recharge the batteries.
2. You should check if the audio source is switched on.
3. You should check if the volume is too low. Adjust the volume to obtain the right level of sound.
4. Push the tuning selector on headphones until the clear sound is obtained. The red LED ? will keep flashing during the selection. When the proper channel is obtained, the red LED ? will remain lit.

NOTE: On some newer TV sets, it may be necessary to turn on or increase the volume of the headphone jack or the audio out jack. Consult the instruction manual of your TV to adjust these settings.

• If you are connected to the TV via the headphone jack, make sure the headphone jack is turned on and that the output level is turned up. (Normally, you can check this by pressing the Menu button on your TV remote control and entering the Set-Up menu. Consult your TV owner's manual for details.)
• If you are connected to the TV via the audio out jacks, make sure the audio out jacks are turned on and that the output level is turned up. (Normally, you can check this by pressing the Menu button on your TV remote control and entering the Set-Up menu. Consult your TV owner's manual for details.)
• If you are still not getting any sound, try the alternate cable connection method using the other included audio cable.

Question: When there is distorted sound

Remedy:

1. Push the tuning selector on headphone until clear sound is obtained. The red LED ? will keep flashing during the selection. When the proper channel is obtained, the red LED ? will remain lit.
2. Push the tuning selector on transmitter to select any of the three channels.
3. Push the selector on headphone again until the clear sound is obtained.
4. The batteries in the headphones are running low. Simply place the Headphones on the transmitter to recharge the batteries.
5. Check if the volume on the audio source or headphones is too high. Adjust the volume to obtain the right level and clear sound.
6. The distance from the transmitter is too large. Move closer to the transmitter.
7. Fluorescent lamps and other audio sources may cause interference. Move the transmitter or headphones elsewhere.
