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.
E Charge the stethoset receiver by placing it into the transmitter’s
charging compartment (see page 16).
The LED stops flashing and the charging process starts.
Always store the stethoset receiver in the transmitter’s
charging compartment to ensure that it is fully charged when
needed. The intelligent battery charging technology prevents
overcharging.
The display during charging can be set so that it automatically
switches off after 30 seconds (see page 32).
