where the signal is weak, the picture may be marred by dots,
show blocking or break-ups. When the signal is extremely weak,
it may be necessary to install a special antenna to improve the
reception.

Possible cause and solution
1. Check if the fuse or circuit breaker is working.
2. Plug another electrical device into the outlet to make
sure it is working or turned on.
3. The power plug is in bad contact with the outlet
4. Check the signal source.
1. Change the colour system.
2. Adjust the saturation.
3. Try another channel. Black-white programme may be
received.
1. Change the batteries.
2. The batteries are not installed correctly.
3. Main power is not connected.
