Preparing the transmitter for use

The transmitter is prepared for wall mounting (recess at the rear of the transmitter). The required mounting material (screws and plugs) is not included in the delivery.

Connecting the transmitter to an audio output of your audio source

• Choose 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.
• Connect the transmitter's audio connection cable:
  • either directly to the headphone socket or
  • to the 1/4" (6.3 mm) adapter and a corresponding headphone socket.
• Set the volume for the headphone output of your audio source to a medium level. If the headphone output volume is set too low, the transmitter automatically switches off.
  Some TVs have a function that mutes the TV loudspeakers when you connect a transmitter. If necessary, change this setting via the operating menu of your TV.

Connecting the transmitter to the mains

• Connect the mains unit to the socket at the rear of the transmitter. Plug the mains unit into a wall socket. The transmitter switches on and the ON/OFF LED lights up green.

Preparing the headphones for use

Opening the battery compartments

• Turn the ear pads in the direction of the arrow until you overcome a slight resistance and lift them off the ear cups.

Inserting and replacing the rechargeable batteries

• Only use NiMH rechargeable batteries, never use standard batteries!
• Insert the supplied rechargeable batteries. Secure the ear pads to the ear cups.
• Charge the rechargeable batteries for at least 24 hours prior to first time use. Subsequent charging time depends on the previous operating time and is up to 18 hours max.
• Place the headphones on the charging cradle of the transmitter. The red LED lights up, indicating that the batteries are being charged. The LED remains lit even when the rechargeable batteries are fully charged.

Using the RS headphone system

Switching on the audio source

• Switch on the audio source. The transmitter automatically switches on and off together with the audio source. The ON/OFF LED lights up green.

Switching on the headphones/adjusting the volume

• First, set the volume on the headphones to a low level.
• Switch on the headphones and set the volume to the desired level.
• Switch off the headphones after use to avoid discharging the batteries.

Optimizing the reception

• Adjust the receiver channel with the TUNE control on the headphones.

However, if reception is subject to interference:

• Change the transmission channel by setting the switch at the bottom of the transmitter to another position and re-adjust the receiver channel with the TUNE control on the headphones. Some electronic devices (e.g. televisions) can cause interference to your wireless headphone system. If this happens, increase the distance between the transmitter and the interference source.
