If when tuning in your TV to the VCR test pattern your TV does not find the test pattern or the pattern when found suffers from interference, it may be due to the VCR output channel clashing with the normal TV transmissions in your area. To prevent this you will need to change the VCR output channel in the following way

1.Remove the aerial input plug from the socket marked (aerial symbol) on the rear of the VCR.

2.Carry out the instructions “Tuning Your Television for the VCR” (see page 14).

3.Carry out the instructions “Setting the VCR output Channel” (see page 17), move the channel number several channels down from the original setting. (example: from 38 to 35).

4.Replace the aerial plug into the socket marked (aerial symbol) on the rear of the VCR.

5.Re-tune your TV to the VCR again by following instructions “Tuning Your Television for the VCR” (page 14).

6.If the problem still exists repeat steps 1 to 5 moving several more channels away from the original setting.
