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.

INSTALLATION  
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.

To prevent accidental erasure of recorded m aterial,  
rem ove the safety tab from the lower left corner of  
the cassette.  
Recording is impossible when the safety tab is  
removed.  
TAPE LIFE  
Slower speed operation in tim e lapse recording  
applies stress to video tape. Tapes should be  
inspected and, if necessary, discarded after the total  
num ber of com plete tape passes (recording and  
playback) exceeds the following lim its:  
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 rem oved, cover the tab hole with tape. In the

2. The pictures per second at each speed.  
3. The speeds at which audio can also be recorded.  
Important  
“Avoid using cassette box fabricated out of  
transparent material.”  
Use the table to select the tape length which gives  
the best com prom ise between tape cost, total  
recording tim e, and elapsed tim e between pictures.  
This is to prevent occurrence of any incorrect

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.
