Frequently Asked Questions - HC8355 PHILIPS

How to recharge the batteries of the Philips HC8355 headphones?

Remove the batteries from the headphones by taking off the ear cushions, place them in the charging compartment of the transmitter. The green LED lights up during charging. A full charge takes approximately 16 hours.

What type of batteries to use for the HC8355 headphones?

Use exclusively NiCd LR03/AAA rechargeable batteries (preferably Philips). Do not use NiMH or alkaline batteries, as this could damage the system.

How to connect the transmitter to an audio source?

Plug the supplied 3.5 mm audio cable into the headphone output of your source (TV, hi-fi system, PC). If the output is 6.3 mm, use the included adapter. Power on the source and increase the volume.

Why is there no sound in the headphones?

Check: 1) The power adapter is properly connected. 2) The headphones are turned on (switch to On). 3) The batteries are charged. 4) The audio source is on and volume is adequate. 5) The tuning is correct (turn the dial).

How to reduce interference or sound distortion?

Adjust the tuning on the headphones. You can also change the channel on the transmitter (switch 1/2) and retune. Move away from sources of interference (neon lights, other radio devices).

What is the maximum range of the wireless headphones?

The effective range is up to 100 meters in open field, with 360° omnidirectional coverage. Obstacles like walls can reduce the range.

Can I use multiple headphones with one transmitter?

Yes, provided that the additional headphones are compatible: operating in the 864 MHz band and capable of detecting a 19 kHz pilot tone. Check the specifications of other devices.

How to clean the headphones and transmitter?

Use a soft, slightly damp cloth. Never use alcohol, thinner, or abrasive products that could damage the casing.

Can the headphones be used with a transmitter of another brand?

It is recommended to use the supplied Philips HC8352 transmitter. Some built-in transmitters may not be compatible due to the advanced technology of the HC8355. Compatibility is not guaranteed.

What to do if the headphones do not charge?

Make sure the transmitter is powered and the green LED lights up. Check that the batteries are correctly placed in the charging compartment. If the problem persists, replace the batteries with new ones (NiCd LR03/AAA).

Benefits of Philips latest RF/FM wireless technology

Wireless transmission

The FM transmitter transmits the stereo audio signal from your audio or video source to your FM headphone without wires.

Wide transmission range

Your FM headphone can receive signals up to 100 meters away.

High-frequency radio system

The FM headphone set uses a high radio frequency as the signal carrier, ensuring a very clear, sharp reception.

Automatic power on/off indicator

The FM transmitter automatically switches on and starts transmitting when audio signals are detected at the audio input (red LED). When no audio signals are detected the FM transmitter automatically switches off after a few minutes.

Rechargeable system

The FM transmitter recharges the headphone's built-in rechargeable LR03/ AAA NiCd batteries. Just place the batteries in the transmitter's battery compartment. The green LED lights up during charging.

General information Controls

Easy transmission

The FM headphone is able to receive signals from the transmitter, even through barriers such as doors, walls and windows.

Multiple headphones with one transmitter

An additional number of headphones and/or wireless speakers can be used with a single transmitter if they:

• operate in the 864 MHz band
• can detect a 19 kHz pilot tone.

Please consult the appliance's electrical specification sheets for confirmation on compatibility.

Basic operation

Troubleshooting

If a fault occurs, first check the points listed below before taking the set for repair.

If you are unable to remedy a problem by following these hints, consult your dealer or service centre.

WARNING: Under no circumstances should you try to repair the set yourself, as this would invalidate the warranty.

Problem Remedy

No sound – Check if the AC/DC adapter is fully inserted into the

AC outlet and that its DC connector is properly inserted into the 12 Volt DC input connector located at the rear of the transmitter.

- Check if the headphone's on/off switch is in the on position.

- Headphone batteries running low.Remove the earcushions.Take out the batteries and put them in the transmitter's recharging compartment for recharging. (See Headphone power supply)

- Check if the audio source is switched on and tuned to a channel with audio.

- Volume not adjusted. Adjust the volume on the audio source/ headphone to a higher level.

- Adjust the headphone's tuning frequency. Turn the tuning wheel until the signal is at its clearest.

- Make use of the HC8352 transmitter. Some transmitters already built into other equipment may not be compatible with the HC8355 headphone because of the advanced technologies used in the HC8355 headphone.

Distorted sound

- Adjust the headphone's tuning frequency. Turn the tuning wheel until the signal is at its clearest.

- Adjust the transmitter's frequency. Select any of the 2 channels of the transmitter. Next adjust the headphone's frequency by turning the tuning wheel until the signal is at its clearest.

- Headphone batteries running low. Remove the earcushions. Take out the batteries and put them in the transmitter's recharging compartment for recharging. (See Headphone power supply)

Troubleshooting

Distorted sound – Check the volume on audio source/ headphone is not set at too high a level. Reduce the volume.- Distance from the transmitter is too large. Move closer to the transmitter.- Interference from fluorescent lamps/ other radio sources. Move transmitter or headphone elsewhere/ change the transmitter's channel.- Make use of the HC8352 transmitter. Some transmitters already built into other equipment may not be compatible with the HC8355 headphone because of the advanced technologies used in the HC8355 headphone.

Maintenance – If the headphone will not be used for a long time,please remove the batteries to prevent leakage and corrosion.- Only replace the batteries with LR03/AAA NiCd batteries (preferably Philips).- Do not leave the headphone near heat sources. Do not expose to direct sunlight, excessive dust, moisture, rain or any kind of mechanical shock.- Do not use alcohol, thinner or petroleum-based substances to clean the headphone or transmitter. Use a slightly dampened chamois cloth to clean the housing.- Do not use cleaning agents containing alcohol, spirits, ammonia or abrasives as these may harm the housing.

Hearing Safety! Continuous use at a high volume may permanently damage your hearing.
