Camera Care &Maintenance

Video equipment lasts well

when its treated well.

Common sense and regard for its susceptibilities will keep itrunning smoothly for a long

time.

Equipment Storage Always return the equipment to its case

after use.

Ensure that the case is stored upright or placed on a flat horizontal surface.

Dont stack heavy pieces of equipment

on top of each other. Put sachets of silica gel in the case to

absorb moisture.


5/15

Equipment Transport

Never bang or drop the video equipment. Ensure that the case is well padded and that

the case cant be flung about or banged. When transporting by car, put equipment on

the floor of the back seat as this prevents it

from falling during sudden stops. On airplanes, carry your camera as carry-on

luggage.


6/15

Wet Weather

Rain and spray can cause shortcircuits or total equipment failure.

Raindrops falling on microphoneswill mar the sound track.

Use an umbrella or wrap thecamera and VTR in a plastic bag if you have to shoot in the rain.

Dont run cables through puddles.


7/15

Heat & Humidity

The temperature in a closed car in the suncan reach over 50C and cause permanent

damage to both video tapes andequipment. If you move suddenly from a cold, dry

environment to a hot, moist one, the dewwarning light on the VTR will light up, theVTR will automatically switch off. It wontoperate again until it dries off inside.


8/15

Prevention / Solution

Allow the equipment time to warm upand acclimatize before switching iton.

Plan extra set-up time into your

production schedule. To dry out quickly, get the equipmentinto a dry-air environment.


9/15

Sea Spray / Salt / Sand

After a day at the beach, clean theequipment thoroughly because: salty air and sea spray is corrosive to videoheads, metal parts of video equipment includingthe chassis and circuit board.

salty air will form a coating on the front elementof the lens.

sand can wreak havoc in the tape transportmechanisms.


10/15

Dust Keep the camera and the VTR in a

dust-free environment. Dust will coat lenses, causeabrasions on the video heads and

lead to drop-outs on the tape.


11/15

Liquid & Food Avoid eating, drinking or smoking

around video equipment, in controlrooms or near editing decks.

Split coffee has accounted for

many loud bangs, blue flashes andlarge repair bills.


12/15

Tape Clogging VTRs left in pause mode for longer

than 30 seconds will start to lift tapeparticles off the tape and clog thehead leading to dropouts and head

damage.


13/15

Magnetic Fields Avoid power transformers, electric

motors, television sets andloudspeakers.

The magnetic fields generated can

scramble the information on tape or interfere with recording.


14/15

Lens Use an air bottle or a lens brush or

special lens cleaning fluid to remove

surface dust. Never rub the lens to remove spots. Use a neutral density filter to protect

the lens from scratches. Fit a lens cap when the camera is not

in use.


15/15

Cable Faults

Most camera problems result fromcable faults.

Look for problems in the cable thatlink your camera to the recorder.

Avoid pulling directly on the cablesor resting heavy objects onexposed cables.
