Power Light: This light is blue when the transmitter is powered on. If the transmitter detects no audio signal for about 5 minutes, the transmitter will enter a low-power mode to save energy. When it detects an audio signal again, it will return to its normal power level and the light will be blue again.
Optical/Coaxial Light: This light is red when the source switch on the rear panel is set to Optical or Coaxial (see below). The light will flash when the transmitter detects an issue with the incoming digital signal (see Troubleshooting if this happens).

Setup

Items not listed under Introduction > Box Contents are sold separately.

Powering the Headphones

The headphones are powered by 2 rechargeable AAA batteries, which must be charged by the transmitter. Use the included batteries only.

With fully charged batteries, you can use the headphones for approximately 10 hours. It takes approximately 6 hours to fully charge them. If this is the first time you are using them, charge them for the full 6 hours.

When the light on the headphones flashes red, the batteries are low on power. The headphones will also “beep” to alert you.

To install the headphone batteries:

Please read the Introduction > Important Safety Notices at the beginning of this manual before installing or replacing the batteries.
Carefully rotate and remove the right ear pad (shown here).
Install the 2 rechargeable AAA batteries (included) in the battery compartment. Make sure their polarities (+ and –) are facing the proper directions.
Reattach the ear pad.

To charge the headphones:

Important: If this is the first time you are using the headphones, charge them for 6 hours before use.

After the batteries are installed, make sure the headphones are powered off.(If they are on, press and hold the power button on the headphones for about 2 seconds. The light next to the button will turn off.)
Place the headband of the headphones on charging dock on top of the transmitter. Make sure that the transmitter is connected to a power outlet and that its Power switch is set to On. The headphones will start charging immediately.
While charging, the Charge light on the transmitter’s front panel will turn green. When it turns off, the headphones are fully charged.

More Important Information About Batteries:

We highly recommend using the included rechargeable batteries. Alternatively, you can use standard NiMH rechargeable batteries, but they will not charge when you place the headphones on the charging dock. You could also use alkaline batteries, though these will also not charge.

To order additional or replacement rechargeable batteries (like the included ones), contact ION Audio’s parts department at ionaudio.com/support.

Setting up the Transmitter & Headphones

General Notes:

If this is the first time you are using the headphones, charge them for full 6 hours before use. See Powering the Headphones above.
If your sound source has built-in speakers or if you are using external speakers with it, you can use Telesounds in addition to those speakers.

Important Notes for TV Users:

Because there are so many different TVs available, these instructions cannot explain how to navigate your specific TV’s menus or set its audio output. Please refer to your TV’s manual to learn how to do this, if necessary.
Your TV may have an audio output setting in its menus that lets you choose between a fixed output or a variable output. If this is the case, we recommend using the fixed output.
- When using a fixed output, the TV’s volume level cannot be changed by its volume
  controls; you must use the –/+ buttons on the headphones to adjust the volume.
- When using a variable output, you can change the TV’s volume level by using its volume controls, but the sound in the headphones may be too quiet.

To set up the transmitter with your TV (or other sound source):

Using the included power adapter, connect the transmitter’s power input to a power outlet.
Connect one of the transmitter’s Audio In connectors to an audio output on your TV:
- To use the TV’s RCA stereo outputs, use the RCA-to-RCA cable to connect them to the transmitter’s RCA (Right & Left) inputs.
- To use the TV’s optical (digital) output, use the optical cable to connect it to the transmitter’s Optical input.
- To use the TV’s coaxial output, use the coaxial cable to connect it to the transmitter’s Coaxial input.
Set the source switch to the type of connection you made in Step 2:
- If you connected to the transmitter’s RCA (Right & Left) inputs, select Audio.
- If you connected to the transmitter’s Optical input, select Optical. The Optical/ Coaxial light on the front of the transmitter will turn red.
- If you connected to the transmitter’s Coaxial input, select Coaxial. The Optical/ Coaxial light on the front of the transmitter will turn red.

When connecting the transmitter to a TV, receiver, DVD player, or hi-fi system, set the Att. switch on the rear panel to -8 dB.

When connecting the transmitter to a CD player, smartphone, tablet, or computer, set the Att. switch on the rear panel to 0 dB.

To set up the headphones with the transmitter:

After setting up the transmitter (see above), set the Power switch on the transmitter to On.
After installing the included batteries in the headphones and charging them (see Powering the Headphones), press and hold the power button on the headphones for about 2 seconds. The light next to the button will turn red.
Wait a few seconds for the headphones and transmitter to connect wirelessly to the transmitter. When properly connected, the light on the headphones will be green.

To adjust the volume on the headphones, use the + and – buttons on the headphones (when they are powered on).

Troubleshooting

If you do not hear any sound in the headphones:

Make sure the power adapter is properly connected to both the power outlet and the power input on the transmitter’s rear panel. Also make sure the Power switch on the transmitter’s rear panel is set to On. The Power light on the front panel should be blue.
Make sure the headphones are powered on and fully charged. The status light next to the power button should be green. See Setup > Powering the Headphones for more information.
Make sure your sound source (TV, receiver DVD player, etc.) is powered on with its volume at an audible level.
Make sure the headphone volume is at an audible level. Use the – and + buttons to adjust it.

If the sound in the headphones is distorted or “clipping”:

Make sure the headphone volume is not too high. Use the – and + buttons to adjust it.
Make sure the headphones are close enough to the transmitter. Also make sure there is a clear line of sight between the headphones and the transmitter.
Make sure the volume of your sound source (TV, receiver, DVD player, etc.) is at an audible level.
If you connected the transmitter to a TV, receiver, DVD player, or hi-fi system, make sure the Att. switch on the transmitter’s rear panel is set to -8 dB.

If the Optical/Coaxial light is flashing (when the source switch is set to Optical):

Make sure the included optical cable is securely connected to both the Optical input on the transmitter’s rear panel and the optical output of your sound source (TV, receiver, etc.).
