REMOTE CONTROL
Installation of batteries
Remove the cover at the back.
Position two batteries of the type AAA/R03/UM4 in the battery compartment. Make sure that the
orientation of the batteries is correct (see drawing at bottom).
Do not mix new and old batteries and do not use different types of batteries.
If the remote control is not used for prolonged periods, remove the batteries from the remote control
to avoid corrosion.
Using the remote control
Direct the remote control at the sensor on the front
panel of the amplifier. When the remote control signal is
received, the unit reacts accordingly. The remote control works
within a range of 6m.
Sometimes the remote control may not work well in direct
strong light. You may have to move the amplifier if it is a
problem.
Malfunction may occur if remote controls of some other
equipments are used near the amplifier.
Do not place any objects on the remote control, as the batteries
may become flat if a key is depressed constantly.
Make sure that there are no obstacles between remote
control and amplifier.
Do not position the amplifier behind tinted glass as it may
reduce the maximum range of the remote control.
