cial attention (e.g. in traffic or when performing skilled jobs).
왘Always keep the headphones/MCA 800 charging adapter at
least 3.94" (10 cm) from cardiac pacemakers or implanted
defibrillators. The headphones/MCA 800 charging adapter con-
tain/s magnets that generate a magnetic field which could cause
interference with cardiac pacemakers and implanted defibrilla-
tors.
왘Do not use the product near water. To reduce the risk of fire or
electric shock, do not expose the product to rain or moisture.
왘Keep the product, accessories and packaging parts out of reach
of children and pets to prevent accidents and choking hazards.
왘Only use the power supply units supplied by Sennheiser.

Displaying the remaining operating time of the
rechargeable battery
When you switch the stethoset receiver on, the Battery LED dis-
plays the remaining operating time/charge status.
To indicate that the operating time is decreasing, each LED segment
slowly dims before it goes off completely.
If the actual operating time differs widely from the specified values,
the rechargeable battery is probably exhausted and should be
replaced. Information on the rechargeable battery can be found on
page 28.
Using the charging reminder function
When the stethoset receiver is switched off and the transmitter
automatically switches off (standby mode), the
Battery LED will
flash back and forth for 10 minutes to remind you to charge the ste-
thoset receiver.
