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:
1. Please read the Introduction > Important Safety Notices
at the beginning of this manual before installing or replacing
the batteries.
2. Carefully rotate and remove the right ear pad (shown here).
3. Install the 2 rechargeable AAA batteries (included) in the
battery compartment. Make sure their polarities (+ and –)
are facing the proper directions.
4. 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.
1. 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.)
2. 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.
