9.Problems and solutions

No picture, no sound.			a. Check that all cables are correctly connected.
			b. Check that the channel has been set correctly.
			c. Check that the test pattern is received correctly.
The picture is far too bright.			Check that the jumper switch has been correctly
			connected.
The picture is far too dark.			Check that the jumper switch has been correctly
			disconnected.
Interference with other channels.		Select a different channel, preferably the middle channel
			of 3 empty channels in the band.
Sound is distorted.			Turn down the volume on the connected appliance.
Infrared does not work.			a. Check that the infrared eye is in the correct position
			on the sensor.
			b. Check that the metal part of the infrared receiver is
			correctly connected.
			c. Check that the aerial wall outlets, aerial amplifiers
			and splitters that are fitted IN the cabling between
			your bedroom and living room are "return channel"
			compatible (5 - 30 MHz).
