Troubleshooting Guide
There is no sound
There is no sound during the first
few seconds after the amplifier
has been switched on
The remote control does not work.
Check the hi-fi components you wish to use are connected properly.
Check that you have selected the correct hi-fi component.
Check the amplifier has not been switched to stand by with the remote
control.
Check the volume control has not been set to minimum.
This is normal. Your amplifier has a special circuit which mutes the sound
during the on/off operation
Check there is no obstruction between the remote control and the IR SENSOR
on the amplifier. The remote control must be pointed directly at the sensor for
correct operation.
Check the batteries - they may be exhausted. Replace them with new
batteries. Never mix old batteries with new ones or different types of battery.
