POWER SUPPLY
The A 200 is powered via the BA 151 rechargeable accuplug
which is both cost-saving and environmentally friendly. The
accuplug has an operating time of approx. 10–12 hours with the
volume set to a medium value. The operating time can be
extended by using a second accuplug (available as an accessory).
With a second accuplug, one accuplug can be stored in the L 200
charging unit to ensure that it is fully charged when needed. Since
the accuplug cannot be overcharged, it can remain in the charging
unit even when it has been fully charged.
PUTTING THE RECEIVER INTO OPERATION
Insert the BA 151 accuplug into compartment ቢ in the A 200.
NB.: The BA 151 accuplug must be charged for 24 hours
before first use! Take special note of the instructions on
accuplug operation on page 12 of this manual!
SWITCHING ON/OFF THE A 200, ADUSTING THE VOLUME
Use the rotary switch ባ located on the bottom of the A 200 to
switch on/off the device and adjust the volume.
THE A 200 HAS A BUILT-IN LIMITER
If the user speaks or if loud and sudden noise occurs, the
amplification is reduced immediately. Unpleasant volume
peaks are thus avoided and the user perceives his own voice as
sounding completely natural. The volume limiter is factory-
adjusted to the optimum setting.
ADJUSTING THE BASS ATTENUATION
You can use the two supplied sealing tapes to seal the small holes
in the back of the headphone systems. The more holes you seal
with the sealing tapes, the greater is the bass attenuation. This
increases the intellegibility without increasing the volume - which
is an advantage for people with a more severe hearing impairment.
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. Replacement ear-cushions are available with different
degrees of softness:
Ǡ Black ear-cushions, firmer version Cat. no. 37080
Ǡ Transparent ear-cushions, softer version Cat. no. 40949
Please order your ear-cushions from your Sennheiser dealer.
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.
