PRECAUTIONS
Safety
• Should any solid object or liquid fall into the cabinet, turn off the unit and have it checked by qualified personnel before operating it any further.
• To disconnect the power cord, pull it out by the
plug. Never pull the cord itself.
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 radiators or air ducts or in a place subject to direct
sunlight, excessive dust, mechanical vibrations or
shock.
• Do not place heavy objects or heat-generating
objects on the VCR, or the cabinet could be damaged or the temperature inside the VCR could rise,
which could cause a fault.
• Never bring a magnet or magnetized object near
the VCR because it will adversely affect the performance of the VCR.
• Do not install the unit in an inclined position.
The unit is designed for operation in a horizontal
position.
Operation
• 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 moisture.
Condensation on the head drum, one of the most
crucial parts of the VCR, will cause damage to the
tape.
The VCR should not be operated for at least 2
hours after being moved from a cold to a hot environment 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 chemically processed cloth, the surface
finish may be degraded or its coating may peel
off.
Repacking
• It is wise to save the packing materials and box in
case you ever need to ship or store your unit.

INSTALLATION
VIDEO CONNECTIONS
Use coaxial cables when connecting a camera and a
monitor to this VCR.
Note: Long cable runs to distant cameras may
cause signal deterioration and/or sync discrepancies. If these problems occur, use video line
amplifiers and/or cameras having phase-adjustable
line-locked vertical sync.
Video Input
In single camera systems, connect the camera to the
Video IN BNC terminal on the VCR rear panel. Use
of a 2:1 interlace camera is highly recommended;
otherwise, the monitor will show vertical distortion
of the TIME/DATE characters.
In multiple camera systems, connect the switcher
output to the Video IN BNC terminal. Because multiple camera systems require synchronization, use
of cameras having line-locked vertical sync or a genlocked master drive/sync source is highly recommended. The use of vertical interval switchers is
also recommended.
Video Output
Connect the monitor to the Video OUT BNC terminal
on the rear panel.
AUDIO CONNECTIONS
Audio can be recorded at all speeds. To hear the
playback sound, use the 08, A24 or A40 speed during playback.

VIDEO CASSETTE SAFETY TAB
To prevent accidental erasure of recorded material,
remove the safety tab from the lower left corner of
the cassette.
Recording is impossible when the safety tab is
removed.
Notes:
• The TAB indicator lights when a cassette without
its safety tab is loaded.
• To record again on a cassette that has its safety
tab removed, cover the tab hole with tape. In the
TIMER mode, the TIMER indicator will flash on
and off if the cassette is inserted without its safety
tab slot covered or intact.
TAPE LENGTH
The total recording time at each of the three tape
speeds depends on the length of the tape used.
The table below shows:
1. The total recording time that can be recorded at
each tape speed mode on T120 and T160 tapes.
2. The pictures per second at each speed.
3. The speeds at which audio can also be recorded.
Use the table to select the tape length which gives
the best compromise between tape cost, total
recording time, and elapsed time between pictures.
Tape Speed Complete Tape Passes

“Avoid using cassette box fabricated out of
transparent material.”
This is to prevent occurrence of any incorrect
operation due to sensor's misdetection.

ALARM INDEX SEARCH
The alarm index search method causes electronic
“marks” to be recorded on the tape at each point
when the ALARM recording begins.
Later, the VCR can find these “marks” automatically,
making it easy to find the beginning of each alarm
for playback.
These check points are permanent until the tape is
erased. A check mark is recorded automatically
each time the VCR starts ALARM recording.
1. Press the PLAY button to start playback.
2. Press the ALARM INDEX button.
3. Press the REW or F.FWD button. The recorder
enters VISUAL SEARCH mode.
4. When the VCR finds a mark, it enters normal
playback mode.
5. Press REW or F.FWD button again to find next
“marked” recording. The recorder advances
tape to the next marked position.
6. Press the ALARM INDEX button again to release
alarm index search.
Notes:
1. Be careful as no alarm input can be detected for
5 seconds immediately after the visual search
mode is entered by pressing the REW or F.FWD
button during the alarm index search mode.
2. When tapes recorded by other VCRs are played
in the alarm index search mode, the VCR may
enter the play mode in a meaningless position.
3. When you have selected “MANUAL” at the
DURATION setting in the ALARM display and the
duration of an alarm recording is shorter than the
values shown below, “marks” may not be detected.

Maintenance
PHILIPS recommends two periodic maintenance
steps to insure the peak performance of the
LTC 3924/62.
1. Periodically make a careful observation of the
quality of the playback video. If there are excessive dropouts (noise specks) across the video picture, and the TRACKING control does not clear
the picture, then head cleaning may be necessary.
Obtain a high quality head cleaning kit, and follow
the directions carefully. The length of time
between cleaning depends on the amount of airborne contaminates 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.
