Setting up thetransmitter
왘Choose asuitable place near your sound source.
왘Separate the transmitterfrom otherwireless devicesin the room
byat least 50 cm/20" to avoid interference.
왘Do not place the transmitterclose to metal objects suchas shelf
bars, reinforcedconcrete walls, etc. as this can decrease the
transmitter’srange.

Connecting thetransmitter to an audio source
You can connectthe transmittereitherto adigital or an analog
audio source (e.g. aTV and astereohi-fi system).
Ifyou connectan audio source to both inputs (digital and analog),
onlythe analog audio source will be reproduced.
왘Switchyour audio sourcesoff before connecting the transmitter.
왘Check the connection possibilitiesof your audio source (audio
output, usuallymarked“OUT”).
왘Selectthe corresponding connection cable and, if necessary, a
suitable adapter
왘Toconnectthe transmitterto your audio source, referto the con-
nection diagram suitable for your audio source (see the follow-
ing chapters). Follow the color codings on the transmitterand on
the cables.

Connection possibility B: 3.5 mm jack socket (analog)
왘Connect the stereo audio cable to the blue Analog 3.5 mm In
audio input (3.5 mm jack socket) of the transmitter and to the
3.5 mm headphone socket of your audio source.
If the headphones socket on your audio source is a 6.3 mm/¼" jack
socket, you require an adapter (3.5 mm jack plug to 6.3 mm/¼" jack
plug, optional accessory) for the supplied 3.5 mm stereo audio
cable.
Some TV models mute the loudspeakers when you connect the
transmitter to the 3.5 mm headphone socket. Other TV models have
their own menu for adjusting the volume of the headphone socket.
Check the menu of your TV for information on how to deactivate the
muting function or adjust the volume. Alternatively, connect the TV
and the transmitter using a different connection possibility (A, C or
D).
B
Adjust the volume of the headphone socket on your TV/audio
source to at least a medium level.
This improves the quality of wireless audio transmission. For
detailed information, please refer to the instruction manual of
your TV/audio source.

Charging the receiver’s rechargeable battery
A complete charging cycle takes about 3 hours. Before using the
receiver for the first time, charge its rechargeable battery for a com-
plete charging cycle without interruption.
When the rechargeable battery is almost empty, the Receiver status
LED lights up red and you hear 2 beeps via the receiver. The Battery
LED on the transmitter lights up white. The receiver switches off
after a few minutes.
왘Place the receiver into the transmitter’s charging compartment
so that the volume buttons face upwards. The receiver is mag-
netically oriented to the correct position. The receiver automati-
cally switches off and the
Battery LED on the transmitter
lights up white. The LED segments display the charge status of
the rechargeable battery. When the rechargeable battery is fully
charged, all LED segments light up white.

Displaying the remaining operating time of the
rechargeable battery
When you switch the 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 26.
Using the charging reminder function
When the 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 receiver.
왘Charge the 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 receiver in the transmitter’s charging com-
partment to ensure that it is fully charged when needed. The
intelligent battery charging technology prevents overcharg-
ing.
The display during charging can be set so that it automatically
switches off after 30 seconds (see page 29).

Connecting headphones or an induction loop to the
receiver
You can connect any headphones or induction loop for hearing aids
with a 3.5 mm jack plug to the RR Flex receiver.
Connecting headphones
We recommend using closed headphones or earphones/ear canal
phones to avoid echoes from e.g. the TV loudspeaker.
왘Connect the 3.5 mm jack plug of the headphones (e.g. MX 475,
supplied) to the jack socket of the receiver.
Connecting an induction loop for hearing aids
You can only use an induction loop if you hearing aid supports an
induction coil (T-coil).
왘Connect the 3.5 mm jack plug of the induction loop (e.g.
Sennheiser EZT 3012, optional accessory) to the jack socket of
the receiver.
왘Set your hearing aid to position “T”.
*optional accessory
If your hearing aid has no position “T” or if you want to use
another connection possibility for your hearing aid or cochlea
implant, please contact your hearing aid acoustician.

set the volume on the receiver to a low level.
왘Do not expose yourself to high volume levels for extended peri-
ods of time.
왘Use a hearing profile (see page 23) that improves especially
speech intelligibility without the need for a high volume.
