02 | SAFETY HINTS FOR BATTERIES
Only use high-quality batteries of popular brands. When inserting the batteries, please respect the
correct polarity (+/-). Do not insert batteries of different types and always replace all batteries at
the same time. Do not combine used batteries with fresh batteries. Please remove batteries when
device is not in use for a longer period. Do not throw the batteries into fire, do not short-circuit and do
not disassemble them! Never charge non-rechargeable batteries – risk of explosion! Remove empty
batteries immediately from the device to avoid the leaking of battery acid. Remove leaking batteries
from the device immediately. Clean the contacts before inserting fresh batteries. Risk of battery acid
burn! In case of contact with battery acid, rinse the affected area immediately with water and contact
a doctor. Batteries can be dangerous to life if swallowed. Keep batteries away from small children
and pets. Do not dispose of batteries in household waste (see also chapter "Disposal of Batteries/
Accumulators").
03 | CAUTION
In order to avoid hearing disorder, make sure that the earphones fit properly in your auricles (please
refer to chapter 07). Wear the earphones throughout the whole period of noise duration.
Should the foam ear pads start to show cracks, do not use them anymore. After prolonged use, the
evidence of cracks is a sign of material fatigue, which is considered a natural wear out. Replacement
foam ear pads are optionally available from DÖRR.
