Always keep the headphones/MCA 800 charging adapter at least 3.94" (10 cm) from cardiac pacemakers or implanted defibrillators. The headphones/MCA 800 charging adapter contain/s magnets that generate a magnetic field which could cause interference with cardiac pacemakers and implanted defibrillators.

Important safety instructions

Always ensure that the power supply unit is

–in a safe operating condition and easily accessible,

–properly plugged into the wall socket,

–only operated within the permissible temperature range,

–not exposed to direct sunlight for longer periods of time in order to prevent heat accumulation.

Varnish or furniture polish may degrade the feet of the transmitter, which could stain your furniture. You should therefore place the transmitter on a non-slip pad to avoid potential staining of furniture.

Do not operate the product near heat sources.

Clean the product only with a soft, dry cloth.

Use only attachments/accessories/spare parts supplied or recommended by Sennheiser.

•explosion,

•fire development,

•heat generation,

•smoke or gas development.

Switch rechargeable battery-powered products off after use.

Do not charge a product with a built-in rechargeable battery if the product is obviously defective.

Only use rechargeable batteries and chargers recommended by Sennheiser.

Only charge rechargeable batteries at ambient temperatures between 5 to 40 °C/41 to 104 °F.

When not using rechargeable batteries for extended periods of time, charge them regularly (about every three months).

Putting the Flex 5000 into operation

Putting the Flex 5000 into operation

Setting up the transmitter

Choose a suitable place near your sound source.

Separate the transmitter from other wireless devices in the room by at least 50 cm/20" to avoid interference.

Do not place the transmitter close to metal objects such as shelf bars, reinforced concrete walls, etc. as this can decrease the transmitter’s range.

Connecting the transmitter to an audio source

You can connect the transmitter either to a digital or an analog audio source (e.g. a TV and a stereo hi-fi system).

If you connect an audio source to both inputs (digital and analog), only the analog audio source will be reproduced.

You can also refer to the beginner’s video guides on how to connect your digital wireless headphone system to a TV: www.sennheiser.com/how-to-videos.

Switch your audio sources off before connecting the transmitter.

Check the connection possibilities of your audio source (audio output, usually marked “OUT”).

Select the corresponding connection cable and, if necessary, a suitable adapter

To connect the transmitter to your audio source, refer to the connection diagram suitable for your audio source (see the following chapters). Follow the color codings on the transmitter and on the cables.

To achieve the best possible listening experience, connect the transmitter to your TV or hi-fi system using the supplied optical digital cable.

Note that your wireless headphone system only supports digital signals coded in the PCM format. Information on how to set the audio format of the connected audio source to PCM can be found in the Sound menu or in the instruction manual of your device.

If an incompatible digital audio signal is being received, the Transmitter status LED flashes white and blue. Audio cannot be reproduced.

TV VOLUME

Adjust the volume of the headphone socket on your TV/audio source to at least a medium level.

This improves the quality of wireless audio transmission. For detailed information, please refer to the instruction manual of your TV/audio source.

If the headphones socket on your audio source is a 6.3 mm/¼" jack socket, you require an adapter (3.5 mm jack plug to 6.3 mm/¼" jack plug, optional accessory) for the supplied 3.5 mm stereo audio cable.

Some TV models mute the loudspeakers when you connect the transmitter to the 3.5 mm headphone socket. Other TV models have their own menu for adjusting the volume of the headphone socket. Check the menu of your TV for information on how to deactivate the muting function or adjust the volume. Alternatively, connect the TV and the transmitter using a different connection possibility (A, C or D).
