6.3 Charging the Batteries in the Headphones
In order to ensure the longest possible service life for the re-

ing your headphone system.
The supplied batteries have been inserted into the headphones
for your convenience.
WARNING: If you operate the headphones on dry
batteries, never try to charge the batteries
using the transmitter’s charging feature. This
would cause irreparable damage to your
headphone system. Dispose of spent batteries
conforming to local waste disposal rules.
