14 English
SilverCrest RFH 2401
Powering the Transmitter Cradle Off
You may power the transmitter cradle off whenever it is not needed. When
powered off, it will not transmit any RF signals but the headphones battery
will still be charged.
1. Slide the On/Off switch (15) on the transmitter cradle to the “OFF”
position. The send indicator (17) on the transmitter goes out.
You may optionally power the transmitter cradle using conventional
batteries. For more information see page 20 – Powering the Transmitter
Cradle Using Batteries.
Synchronising the Headphones and Transmitter
Cradle
After powering the headphones and the transmitter cradle on, both devices
should synchronise automatically. This process may take a while
(sometimes more than 1 minute), but normally you just have to be patient.
Under unfavourable circumstances, however, the audio signal may be
subject to interference. This may happen if you are using a baby phone or
a wireless keyboard and mouse set nearby. In this case you can
synchronise the devices manually to locate an interference-free channel.
1. Power the transmitter cradle on by sliding the On/Off switch (15) on the
transmitter cradle to the “ON” position.
2. Power on the connected audio source and start playback. The send
indicator (17) on the transmitter cradle should light up green.
3. Slide the mode selection switch (4) of your headphones to the “WL”
position.
4. Power the wireless headphones on by pressing the On/Off button (10)
once.
5. Press and hold the synchronisation button (2) of the headphones and
the synchronisation button (14) of the transmitter cradle for at least 1
second.
The RF reception indicator on the headphones (5) and the send
indicator on the transmitter cradle (17) start blinking. As soon as both
devices have synchronised, both indicators will light up green.
6. If necessary, repeat step 5 if you are not satisfied with the reception
quality or you still have interference from other devices.
English 15
SilverCrest RFH 2401
Synchronising the transmitter cradle and the headphones
can take a while. If there are many wireless devices nearby
using the 2.4 GHz RF technology, the transmitter cradle and
headphones first have to find a free communications
frequency. Any frequencies that are already occupied by
other devices will not be used. This is also known as “WLAN
Skipping and Hopping”.
Adjusting the Volume
1. Press the VOL+ button (1) once or several times to increase the sound
volume.
2. Press the VOL- button (3) once or several times to decrease the sound
volume.
If you have connected your headphones to an external audio source, you
may also adjust the volume directly on the audio source (e.g. by using the
remote control of your hi-fi equipment). However, please remember that
many audio devices provide a constant signal level on their Cinch audio
outputs, thus not allowing a volume adjustment when using this type of
connection.
Receiving Radio Stations
You may change the operating mode of your headphones to FM radio
reception at any time.
1. Power the headphones on by pressing the On/Off button (10) once. The
power indicator (8) will light up orange.
2. Slide the mode selection switch (4) of your headphones to the “FM”
position. The radio reception indicator (5) will not light up if no radio
station has been tuned-in. It will light up green as soon as a station has
been properly tuned in.
3. Press the Search button (2) on the headphones once to search for the
next available station.
During radio station scanning the radio reception indicator
(5) will blink green.
4. Each press of the Search button will find the next available station until
the end of the FM band has been reached. After this the scan will
automatically continue from the beginning of the FM band.
16 English
SilverCrest RFH 2401
The FM signal reception depends on environmental conditions. If the
desired station cannot be received without noise or interference, try
changing your location.
The last tuned-in station will not be saved when changing the operating
mode or after powering the headphones off.
To use the built-in FM tuner it is not necessary to power the transmitter
cradle on. You may turn it off by pressing the On/Off button (15).
Using the Headphones with a Cable
If your location is close to the audio source and you don’t wish to make
portable use of your headphones, you may use them with a normal cable
connection. In this case you don’t need the wireless capabilities of the
transmitter cradle.
For cable operation, use one of the supplied audio cables (see page 7 –
Package Contents).
1. Music output via the audio cable is possible while the headphones are
powered off. To save battery power, press the On/Off button (10) to
power the headphones off.
2. Connect one end of the audio cable to the audio input socket (6) of your
headphones. Connect the other end of the cable to the headphones
output socket of your hi-fi equipment.
If your hi-fi equipment has a 6.3 mm stereo socket, connect the adapter
plug (see page 7 – Package Contents) to the cable.
You may also connect the adapter cable (see page 7 – Package
Contents) to the cable to use any of the Cinch audio outputs of your hi-fi
equipment.
With this type of connection, the headphones work as a
passive device. The volume can therefore only be adjusted
on the audio source.
Switching to radio reception is not possible during cable
operation. If you want to listen to radio stations, you must
first disconnect the connection cable from the audio input
socket (6) of your headphones.
English 17
SilverCrest RFH 2401
Battery Operation
You may power both the transmitter cradle and the headphones using
conventional batteries. Batteries are not included in the package.

Käyttötarkoitus
Tämä on kotikäyttöön tarkoitettu sähkölaite. Laite ei sovellu käytettäväksi
ulkona tai trooppisilla alueilla. Laitteessa saa käyttää ainoastaan laitteen
turvallisuusstandardien ja sähkömagneettisen yhteensopivuuden ja
suojausvaatimusten mukaisia lisälaitteita. Tämä laite täyttää kaikki CEvaatimustenmukaisuuslausekkeen ehdot ja standardit. Jos laitteeseen
tehdään muutoksia ilman hyväksyntää, em. määräykset eivät ehkä enää
täyty. Valmistaja ei vastaa mahdollisista laite- tai henkilövahingoista, jotka
aiheutuvat luvattomista muutoksista. Käytä vain valmistajan suosittelemia
lisälaitteita.
Korjaukset
Korjaukset ovat tarpeen, jos laite on millään tavoin vahingoittunut, esim. jos
nestettä on joutunut laitteen sisään, laite on altistunut sateelle tai
kosteudelle, se ei toimi normaalisti tai se on pudonnut. Jos laitteesta tulee
savua tai epätavallista hajua tai ääntä, katkaise virta välittömästi. Näissä
tapauksissa laitetta ei saa enää käyttää, ja valtuutetun huollon on
tarkastettava se. Ota yhteys valtuutettuun huoltoliikkeeseen, kun tarvitaan
korjausta. Älä avaa itse laitteen tai sen oheislaitteiden koteloa. Käytä
puhdistamiseen puhdasta, kuivaa liinaa. Älä käytä syövyttäviä nesteitä.
