Frequently Asked Questions - CDC-IR30 Concept

How do I connect the CDC-IR30 headphones to my device?

These headphones use infrared (IR) wireless technology. No pairing is required. Simply insert batteries, turn on the headphones, and select the correct channel (A or B) that matches your transmitter. Ensure there is a clear line of sight within 10 feet.

What batteries do I need, and how do I install them?

You need 2 AAA batteries (not included). Open the battery cover on the earpiece, insert the batteries with correct polarity, and close the cover.

Why is the LED indicator not lighting up?

First, check that the batteries are installed correctly and have charge. Ensure the on/off button is pressed to turn on. If still off, try replacing the batteries.

Can I use these headphones with my TV?

Yes, if your TV has an IR audio transmitter or you have an external IR transmitter connected. The headphones are compatible with most in-vehicle audio/video systems using IR.

What is the range and coverage of the IR signal?

The headphones have a 270-degree IR capture angle and a range of up to 10 feet (about 3 meters). For best performance, maintain a direct line of sight to the transmitter.

How do I adjust the volume?

Turn the volume control wheel located on the earpiece to increase or decrease the volume level.

Why is sound only coming from one earpiece?

Check the channel selector switch – ensure both earpieces are set to the same channel (A or B). Also verify the transmitter channel matches. Weak or dead batteries can also cause this.

How should I clean and maintain the headphones?

Wipe the surface with a soft, dry cloth. Do not use water, solvents, or place in humid areas. Store in a cool, dry place away from heat sources.

Can I use rechargeable AAA batteries?

Yes, rechargeable AAA batteries (NiMH) can be used. Note that the battery voltage is 1.2V per cell, which may slightly reduce operating time compared to alkaline.

What is the warranty on the CDC-IR30?

The manual does not specify warranty details. Please contact Concept or your retailer for information. Do not attempt to open the headphones as it will void the warranty.
