R User and Installation Guide Unpacking: Check that this package contains: One set of 2.4 GHz Digital Wireless Headphones, one 2.4 GHz Digital Audio transmitter, one AC adapter, one dual RCA audio cable. Step 1 Connecting the transmitter The transmitter connects to a line-out interface via the supplied RCA cable. Most audio devices provide a line-out interface. If no line-out interface is available, the transmitter can also be connected to other audio outputs by using an appropriate adapter.
R User and Installation Guide Step 2 Placing the transmitter The operating range essentially depends on how many obstacles there are between the transmitter and the headphones. Therefore, it should be carefully considered where to place the transmitter. Below, two examples are given. In the first example, there are 4 walls between the transmitter and the receiver. The transmission may be interrupted.
R User and Installation Guide Step 3 Installing the headphone batteries Two AA (UM-3, R6, Mignon - 1.5 V) batteries are required to operate the headphones. Rechargable batteries with a sufficiently high voltage can be used as well. Choosing batteries with a high capacity (mAh) will extend operating time. There are two battery compartments, located on both sides, each housing one battery. To access each battery compartment, push on the outer edge of the battery lid. This will release the battery lid.
R User and Installation Guide Step 4 Operating the headphones After powering up the transmitter, the transmit light will light for approximately 5 seconds while the transmitter initializes. After initialization, the transmit light will go out. Once audio is detected at the audio input, the transmit light will light and the transmitter will transmit the audio signal. Set the volume control of the headphones to minimum. Then, switch on the headphones and slowly increase volume.
