Using the Set 840-TV system
Storing and charging the receiver
Do not store the receiver on a glass dummy head, chair
armrest, or similar for long periods of time as this can
reduce the contact pressure of the earbows. Furthermore,
with the earbows pulled apart, the receiver remains
switched on.
̈ After use, place the receiver
into the transmitter’s charging
compartment 6 without exer-
ting too much pressure.
The receiver automatically
switches off.
The Sennheiser logo can face
the operation indicator
0
or away from it.
When the receiver is placed cor-
rectly into the charging compart-
ment, the indicator 9 lights up:
red: The battery is being charged.
green: The battery is fully charged.
With a fully charged battery, the operating time is up
to 9 hours.
The transmitter remains switched on during
charging. If you have a second receiver, it can be used
with the transmitter while the discharged first
receiver is being charged.
Always store the receiver in the transmitter’s
charging compartment 6 to ensure that it is fully
charged. The intelligent battery charging technology
prevents overcharging.
