Additional Information
Remedy
• Connect the AC power cord securely.
• Make sure the VCR is not locked. To unlock, hold
down POWER on the VCR until the H indicator
disappears.
• Moisture condensation occurs. Turn the power off,
unplug the AC power cord and leave the VCR to dry
for over an hour.
• The clock stops if the VCR is disconnected from the
wall outlet for more than one hour. Reset the clock
(and timer).
• Make sure the TV is set to the channel for the VCR. If
you are using a monitor, set it to video input.
• Adjust the tracking with the TRACKING+/– buttons.
• The video heads are dirty (see below). Clean the video
heads using the Sony T-25CL or T-25CLW video head
cleaning cassette. If these cleaning cassettes are not
available in your area, have the heads cleaned at your
nearest Sony service facility (a standard service charge
will be required). Do not use a commercially available
liquid type cleaning cassette other than Sony's, as they
may damage the video heads.
• The video heads may have to be replaced. Consult
your local Sony dealer for more information.
• Adjust the vertical hold control on the TV or monitor.
• The tape is defective. Use a new tape.
