PRECAUTIONS
Safety
Operation
• Should any solid object or liquid fall into the cabi-
net, turn off the unit and have it checked by quali-
fied personnel before operating it any further.
• To disconnect the power cord, pull it out by the
plug. Never pull the cord itself.
• Condensation
If you pour a cold liquid into a glass, water vapor
in the air will condense on the surface of glass.
This is the condensation of m oisture.
Condensation on the head drum , one of the m ost
crucial parts of the VCR, will cause dam age to the
tape.
Installation
• Choose a location in which air can pass through
the ventilation holes in the bottom , top and back
of the unit to prevent it from overheating.
• Do not install the unit near sources such as radi-
ators or air ducts or in a place subject to direct
sunlight, excessive dust, m echanical vibrations or
shock.
• Do not place heavy objects or heat-generating
objects on the VCR, or the cabinet could be dam -
aged or the tem perature inside the VCR could rise,
which could cause a fault.
The VCR should not be operated for at least 2
hours after being m oved from a cold to a hot en-
vironm ent to avoid condensation from occurring
on the head drum .
Cleaning
• Be careful; when surface of the case is wiped with
a volatile agent such as benzine, alcohol, thinner,
etc., or a chem ically processed cloth, the surface
finish m ay be degraded or its coating m ay peel
off.
• Never bring a m agnet or m agnetized object near
the VCR because it will adversely affect the per-
form ance of the VCR.
• Do not install the unit in an inclined position.
The unit is designed for operation in a horizontal
position.
Repacking
• It is wise to save the packing m aterials and box in
case you ever need to ship or store your unit.

VIDEO CONNECTIONS
AUDIO CONNECTIONS
Use coaxial cables when connecting a cam era and a
m onitor to this VCR.
Audio can be recorded at all speeds. To hear the
playback sound, use the 08, A24 or A40 speed dur-
ing playback.
Note: Long cable runs to distant cam eras m ay
cause signal deterioration and/or sync discrep-
ancies. If these problem s occur, use video line
am plifiers and/or cam eras having phase-adjustable
line-locked vertical sync.
Audio In: Accepts an audio signal from a cam era,
external sound equipm ent, or another recorder
(Line: –8 dBm , 50 kohm ).
Audio Out: Provides an audio output for a m onitor
or another recorder (–9 dBm , 600 ohm , unbalanced).
Video Input
In single cam era system s, connect the cam era to the
Video IN BNC term inal on the VCR rear panel. Use
of a 2:1 interlace cam era is highly recom m ended;
otherwise, the m onitor will show vertical distortion
of the TIME/DATE characters.
In m ultiple cam era system s, connect the switcher
output to the Video IN BNC term inal. Because m ul-
tiple cam era system s require synchronization, use
of cam eras having line-locked vertical sync or a gen-
locked m aster drive/sync source is highly rec-
om m ended. The use of vertical interval switchers is
also recom m ended.

Maintenance
PHILIPS recom m ends two periodic m aintenance
steps to insure the peak perform ance of the
LTC 3924/62.
1. Periodically m ake a careful observation of the
quality of the playback video. If there are exces-
sive dropouts (noise specks) across the video pic-
ture, and the TRACKING control does not clear
the picture, then head cleaning m ay be necessary.
Obtain a high quality head cleaning kit, and follow
the directions carefully. The length of tim e
between cleaning depends on the am ount of air-
borne contam inates around the tape recorder
and/or cassette.
2. Have the LTC 3924/62 inspected every 3500 hours
of continuous usage by the dealer from whom the
recorder was purchased.
