RECHARGEABLE ACCUPACKS HAVE A "CHARGING CYCLE"
¿
The charging time of the accupack depends on how long you have used your stethoset receiver. General
rule:
OPERATING TIME x 3 = CHARGING TIME
Example:
listening: 1 hr listening: 2 hrs
recharging: 3 hrs recharging: 6 hrs
RECHARGING THE BA 151 ACCUPACK
Do not let the rechargeable accupacks become completely flat. If you do, they will be exhausted and cannot
be recharged ("total discharge"). This happens e.g. when flat accupacks remain uncharged for some time.
Please observe the three following rules:
If you notice that the accupack is going flat, switch off the stethoset receiver and recharge the accupack
immediately. If you have a spare accupack you can use it in the meantime.
Immediately recharge the accupack after each use, no matter whether it is fully or only partly discharged.
Charge the accupack for 24 hours before you use it for the first time!
Please note: With both charging possibilities, the accupacks are also recharged when the
transmitter is switched off but remains connected to the mains.
ENVIRONMENT AND HEALTH
Devices powered by rechargeable accupacks are environmentally friendly. 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 or has been damaged due to total
discharge, 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.)
According to today's scientific knowledge, the radio waves emitted by this device are by no means harmful.
listening: 3 hrs
