Note that the Set-up switch S2 section 1 must also be set to the correct position to suit the type of
VCR. For most VCRs this switch should be “OFF”. If in doubt, try this first.
Some Sony and Sanyo VCRs employ irregular sampling. In such cases, switch S2 Section 1 should
be “ON”. If set incorrectly, some cameras may not be recorded.
Do a test recording to make sure that the all cameras are correctly recorded and replayed.
