Replacing The Ear-Cushions - Sennheiser IS 380 Notice D'emploi

ADJUSTING YOUR HI-FI SYSTEM OR TELEVISION
Please refer to the operating instructions of your hi-fi system or television to
find out whether the volume control also adjusts the headphone output or
whether it has a separate volume control. With a modern TV set, you can
adjust the volume of the headphone socket independent of the speaker
volume. The manual will also tell you how to turn off the loudspeakers.

REPLACING THE EAR-CUSHIONS

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. Please order your ear-cushions
from your Sennheiser dealer.

FREE LINE OF SIGHT
Infra-red light from the TI 380 transmitter is transmitted in the same way as
the light from a light bulb.
Do not obstruct the path of the light between the transmitter and the
receiver, and stay in the room where the transmission is taking place!
There is a simple rule:
If you can see the transmitter from where you are,
transmission can take place without any interference.
VOLUME UP? – NO!
When people use headphones, they tend to choose a higher volume than
with loudspeakers. Listening at high volume levels for long periods can lead
to permanent hearing defects. Please protect your hearing, Sennheiser
headphones have an excellent sound quality even at low volumes.
