Connecting the transmitter (Fig. 1)

Removing the ear cushions (Fig. 2 and 3)

The ear cushions are secured to the earcups by means of a quarter turn fastener. To remove an ear cushion, turn it in the direction of the arrow until you overcome a slight resistance and lift it off the earcup.

Inserting the rechargeable batteries (Fig. 4)

Remove the left ear cushion (Fig. 2 and 3).

Insert the rechargeable batteries.

Attention: Observe correct polarity when inserting the batteries!

Charging the rechargeable batteries

For charging the batteries, place the headphones on the charging cradle of the transmitter. (The headphones automatically turn off during charging.) The red LED “CHARGE” lights up during the charging process. If the batteries are fully charged, the transmitter automatically switches to trickle charging and the red LED “CHARGE” flashes slowly.

Charge the batteries for at least 16 hours prior to first time use. Subsequent charging time is about the same time as the previous operating time.

Always store the headphones on the transmitter to ensure that they are fully charged when they are needed. The intelligent battery charging technology prevents overcharging. If you do not use the head-phones for extended periods of time, please remove the batteries and disconnect the transmitter’s mains unit from the mains.

Nearly discharged batteries will significantly reduce the sound quality. Approx. 10 minutes before the batteries are completely discharged, an acoustic warning signal is produced (two long beeps, see table on page 16).
