Condensation
• When this unit is moved from a cold to a warm
place abruptly, the vapor in the warm air will
come into contact with the head drum or the
tape guides, which are not warmed enough.
When chilled, the vapor turns into droplets of
water. This state is known as condensation.
When condensation occurs, the videotape
adheres to the head drum or the tape guides
and will be damaged.
• Condensation occurs on this unit in the fol-
lowing circumstances:
* It is moved abruptly from a cold place to a
warm place.
* It is used in a place immediately after the
heater has been turned on, or when cold
breeze from an air-conditioner blows onto it.
* It is used at a place of high humidity.
• When condensation occurs, the monitor dis-
plays the following warning:
When a cassette tape is loaded, do not trans-
port e.g., from a cold outdoor place to a warm
room thus subjecting the unit to drastic tem-
perature changes.
After moving the unit, do not use it until the
inner mechanism stabilizes.
Leave the unit with the power ON and wait
until the WARNING message disappears.
• Prevention of condensation
When transporting BR-DV6000 from a cold
to a warmer place abruptly, first remove the
cassette tape. Then place BR-DV6000 in a
plastic bag and seal it before transporting.
Take out BR-DV6000 from the sealed plastic
bag only after it has the same temperature
as the surroundings.

Ⅵ For recording and storing videotapes in the best condition
Observe the following instructions for the best recording and storage of videotapes.
• Take care of the conditions of handling videotapes.
It is recommended that you record and store videotapes in the environment below.
Storage
Recording Short period Long period
(Up to 10 years) (Over 10 years)
Temperature 17°C to 25°C 15°C to 23°C 15°C to 19°C
Humidity 30% to 70% 40% to 55% 25% to 35%
Hourly temperature change Less than 10°C – –
Hourly humidity change Less than 10% – –
• Do not leave the videotapes neglected for a long period.
If videotapes are left wound for a long period of time, it may result in distortion of the tape. Also it
may cause tape-to-tape adhesion (known as blocking). It is recommended that videotapes be
unspooled and rewound once a year for refreshing.
• When tapes are not in use, store them in cases and on end.
Storage cases protect videotapes from humidity, dust and ultraviolet. Keep tapes in cases and do
not store them lying flat. When housed in a horizontal position, pressure from other tapes can
cause distortions and deformations of the tape edges.
