ACCUPACK OPERATION

PWhen the accupack becomes weak (noise interference and sound distortion are sure signs of a weak accupack), switch off the receiver and recharge the accupack. (If necessary, use a second accupack to listen while the first accupack is being recharged.)

PRecharge the accupack immediately when it is flat. If the accupack is flat but is left in the switched on receiver, this reduces the service life of the accupack (“total discharge”).

PAs far as possible, use the full capacity of an accupack before you recharge it. Frequent short discharge and recharge cycles prematurely reduce its charging capacity.

CHARGING THE ACCUPACKS

The stethoset receivers are powered by BA 151 accupacks which can be recharged either separately or in the receivers. Depending on the application, there are different possibilities for recharging the accupacks.

The BA 151 can be recharged

Pin the Set 150 and Set 300 transmitters,

Pin the L 151-2 charger (suitable for charging two individual accupacks) or

Pin the L 151-10 charging unit.

For commercial use, Sennheiser offers charging and transport/storage units for recharging a larger number of stethoset receivers at a time.

The BA 151 accupack must be charged for 24 hours before first use! Please refer to the corresponding section in the operating manual of your infra-red transmission system or the operating manuals for the chargers.

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).
