Displaying the remaining operating time of the
rechargeable battery
When you switch the stethoset receiver on, the Battery LED
displays 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
32.

Battery LED Meaning
Always store the stethoset receiver in the transmitter’s
charging compartment to ensure that it is fully charged
when needed. The intelligent battery charging technol-
ogy prevents overcharging.
The display during charging can be set so that it automat-
ically switches off after 30 seconds (see page 37).
