Important safety information
왘Please read this instruction manual carefully and completely before
using the product.
왘Make this instruction manual easily accessible to all users at all times.
Always include this instruction manual when passing the product on to
third parties.
왘This instruction manual is also available on the Internet at
www.sennheiser.com.
Preventing health problems
왘Before using the product, set the volume to a low level. To protect your
hearing, avoid listening at high volume levels for long periods of time.
왘Do not use the product in situations which require special attention
(e.g. in traffic or when performing skilled jobs).
The product generates stronger permanent magnetic fields that could
cause interference with cardiac pacemakers and implanted defibrillators
(ICDs).
왘Always maintain a distance of at least 3.94” (10 cm) between the ear
piece housing and the cardiac pacemaker or implanted defibrillator.
Preventing damage to the product
왘Always keep the product dry and do not expose it to extreme temper-
atures (normal operating temperatures: 5°C/41°F to 40°C/104°F).
왘Use the product with care and store it in a clean, dust-free environ-
ment. Varnish or furniture polish may degrade the feet of the trans-
mitter, which could stain your furniture. You should therefore place the
transmitter on a non-slip pad to avoid potential staining of furniture.
왘Switch the headphones off after use to conserve battery power.
Remove the batteries if the headphones will not be used for extended
periods of time.
Preventing damage to the power supply unit
왘To reduce the risk of fire or electric shock, do not expose the product to
rain or moisture.
왘Unplug the mains unit from the wall socket to completely disconnect
the product from the mains, during lightning storms or when unused
for long periods of time.
왘Only operate the mains unit from the type of power source specified in
the chapter “Specifications”.
왘To prevent heat accumulation, always ensure that the mains unit is in
a safe operating condition and easily accessible, properly plugged into
the wall socket and not covered or exposed to direct sunlight for longer
periods of time.
왘Only use the power supply units, charging cables and accessories
recommended by Sennheiser. An overview can be found on
www.sennheiser.com.

Putting the RS 220 into operation
Setting up the transmitter
왘Choose a suitable place near your audio source (e.g. TV, stereo or home
cinema system). Avoid placing the transmitter close to metal objects
such as shelf bars, reinforced concrete walls, etc. as this can decrease
the transmitter’s range.
It is not necessary that the transmitter and headphones are in the
same room, so you can move around freely in the home or outside in
the garden.

niently toggle between these audio sources with a key press (see
page 21).
왘Switch your audio source off before connecting the transmitter.

Integrating the transmitter into an existing connection between devices
You can integrate the transmitter into an existing connection between
your audio source and an additional device. By way of example of an ampli-
fier as an additional device, this chapter describes how to integrate the
transmitter into an existing connection.
왘Pull out the plug of the audio cable from the desired input (“IN”) on the
amplifier.
왘Connect this plug to a suitable input (“IN”) on the transmitter (see
page 7).
왘Connect an additional identical audio cable to the output (“OUT”) on
the transmitter and to the input (“IN”) on the amplifier.
To keep the digital connection up even when the transmitter is switched
off:
왘Switch the loop through mode on (see page 17).
The analog connection (RCA/SCART/headphone socket) is kept up
when you disconnect the transmitter from the mains.
The digital connection (coaxial/optical) is interrupted in this case.

Charging the rechargeable batteries inside the headphones
Charge the rechargeable batteries for at least 16 hours prior to first time
use. The operating time is up to 8 hours.
왘Place the headphones on the charging contacts Aof the transmitter.
The rechargeable batteries are being charged. The Battery LED Hlights

goes off.
Adjusting the headband of the headphones
For good sound quality and best possible comfort, the headband has to be
adjusted to properly fit your head. To do so, adjust the headband 1via its
snap-in locking mechanism:
왘Wear the headphones so that the headband 1runs over the top of
your head.
왘Adjust the length of the headband so that
– your ears are completely inside the earpads,
– you feel even, gentle pressure around your ears,
– a snug fit of the headband 1on the head is ensured.
16h
Always store the headphones on the headphone holder to ensure
that they are fully charged when they are needed. The battery
charging technology prevents over-charging.
