Drift

1. Slå på/av

To power on the headphones, slide the power switch located on the headphone earcup to the 'ON' position. The power indicator light on the headphones will illuminate.
For å slå av, skyv strømbryteren til «AV»-posisjonen.
The transmitter typically powers on automatically when connected to an active audio source and power.

2. Justere volumet

Use the volume control dial or buttons located on the headphones to adjust the listening volume to your preference. Ensure the audio source volume is set to a reasonable level before adjusting headphone volume.

3. Muting Function

The headphones feature an automatic muting function. If the infrared signal is lost (e.g., moving out of range or line of sight), the audio will mute to reduce noise disturbance. Sound will resume automatically when the signal is re-established.

4. Reception Range

The effective reception range for these infrared headphones is up to 8 meters (approximately 26 feet) from the transmitter. For optimal performance, maintain a clear line of sight between the headphones and the transmitter. Obstacles such as walls, furniture, or even people can block the infrared signal.

Vedlikehold

Rengjøring

Wipe the headphones and transmitter with a soft, dry cloth. Do not use abrasive cleaners, solvents, or strong detergents, as these can damage the surfaces. Avoid getting moisture into any openings.

Batteripleie

To prolong battery life, fully charge the NiMH battery before first use and after extended periods of non-use.
If using AAA alkaline batteries, replace them when audio quality degrades or the headphones fail to power on.
Ikke utsett batterier for sterk varme eller direkte sollys.
