CLEANING / REPLACING THE EAR-CUSHIONS
Use a damp cloth for cleaning your stethoset receiver. Do not use any sol-
vents.
The ear-cushions can easily be removed from the headphones and cleaned
with warm soapy water. From time to time, however, the ear-cushions should
be replaced for reasons of hygiene. Replacement ear-cushions are available
with different degrees of softness:
E Black ear-cushions, firmer version EP1 Cat. no. 04655
E White ear-cushions, softer version EP2 Cat. no. 04656
Please order your ear-cushions from your Sennheiser dealer.
ENVIRONMENT AND HEALTH
Devices powered by rechargeable accupacks are kind to the environment.
This energy source can be recharged many times. Conventional batteries, on
the other hand, must be disposed of as special waste after they have been
used just once. If an accupack should be defective, it is then recycled - the
dealer who sold it to you will take it back and will also supply you with a
new, original Sennheiser accupack. (Recycling methods differ in different
countries).
