Frequently Asked Questions - KTL-5004IV Kaiser
How do I connect the headphones to my TV?
Connect the transmitter to your TV using the supplied audio cables. Most devices use the headphone jack or RCA connectors. Place the transmitter near the TV, then switch on the headphones and they will automatically pair with the transmitter.
How long do the batteries take to charge?
The headphones typically require about 3 hours to fully charge. Place them on the transmitter dock, ensuring the charging contacts touch. A red LED indicates charging, which turns green when fully charged.
Can I use these headphones with other audio sources?
Yes, the transmitter can be connected to any audio source with a headphone output or line-out, such as a smartphone, tablet, or Hi-Fi system. You will need the appropriate cable (3.5mm or RCA).
Why is there no sound in the headphones?
Check that the transmitter is powered and correctly connected to the TV. Ensure the volume on both the TV and the headphones is turned up. If the headphones are not on the dock, the battery may be empty. Also verify that the infrared transmitter and the sensor on the headphones are clean and unobstructed.
How far away from the transmitter can I move?
The effective range is up to 10 meters in a clear line of sight. Obstacles such as walls or heavy furniture can reduce the range. Maintaining a direct view of the transmitter ensures the best reception.
Can I use the headphones while they are charging?
No, the headphones cannot be used while on the charging dock. They are designed to be used wirelessly after being fully charged. Charging while listening would require a wired connection, which is not supported.
How do I clean and maintain the headphones?
Use a soft, dry cloth to wipe the ear cushions and headband. Do not use water or cleaning chemicals directly. For stubborn dirt, slightly dampen the cloth. Avoid getting moisture into the openings, and store the headphones in a cool, dry place.
Are there spare parts available?
Yes, you can purchase spare parts such as ear cushions, headbands, and power adapters from the manufacturer or authorized resellers. Contact Kaiser customer service for details on compatible parts and ordering.
What is the frequency response and sound quality?
The headphones deliver a frequency response of 20 Hz to 20 kHz, covering the full audio spectrum. The 40 mm drivers provide clear mids and highs, with adequate bass for an enjoyable TV listening experience.
How do I troubleshoot interference or crackling sounds?
Interference can occur from bright light sources (e.g., sunlight or halogen lamps) interfering with the infrared signal. Move the transmitter away from direct sunlight or bright lights. Also, avoid placing obstructions between the transmitter and headphones, and ensure both devices are on the same channel if multiple transmitters are present.
