Inserting Battery and Effective Range of the Remote
Remove the back cover to reveal the battery compartment and make sure the batteries are inserted
the right way round. Suitable battery types for this remote are AAA, IEC R03 1.5V.
Do not combine a used, old battery with a new one or mix battery types. Remove dead batteries
immediately to prevent acid from leaking into the battery compartment. Do not expose to excessive
heat such as sunshine, fire or similar. Dispose of them in a designated disposal area.
The performance of the remote control will deteriorate beyond a distance of five metres or outside
an angle of 30 degrees from the centre of the television. If the operating range becomes reduced the
batteries may need replacing.
Control and Input Connection
A wide variety of external equipment can be connected to the input sockets on the side of the
television.
Whilst all the necessary adjustments and controls for the television are made using the remote
control, the buttons on the television may be used for some functions.
