Preparing battery packa
Prepare 2 or 3 timea more battery power then you plan to uae.
The published battery capacity is measured m a continuously playing VCR
at room lemperaiure starting with a fully charged battery. Fast winding or
rewinding uses much power than normal playing Conseguently, battery
consumption Oecomes taster whert these operations are performed
frequently.
Battery conaumption is faater in a cold climate
Cold climates reduce the efficiency of a battery and cause it to run out
more quickly
When to replace battery packs
When a battery pack is fully discharged, the POW€H lamp starts ohnking
slowly. Dunng recording, 'BATTERY' also starts lighting on the screen.
Replace the battery when the POWER lamp starts blinking rapidly
Turn off the video recorderfmonitor power before replacing the battery.
Especially during recording, keep the cassette inside the cassette holder
while replacing the battery. When a Iresh battery is attached, recording
can be resumed snnoothly without any picture distortion.
Notes on charging
Before using a battery pack, charge it fully A newly purchased battery
pack also needs to be charged before its first use.
Recharge a battery pack only whan it is fully uaed out
Avoid recharging only partly used battery packs. Reoealed charging of
partly discharged battery packs reduces their capacity and shortens their
overall life span. The original capacity can sometimes be recovered by
fully discharging and then fully recharging the battery pack.
Rechargeable battery packs
Battery pack care
• Remove the battery pack from the video recorder/monitor after use, and keep it m a cool place. When
the battery pack is installed on a video recorderrmcniior. a small amount of current flows to the recorder
even if the POWER switch is turned oft This causes overdiseharge and so shortens battery life.
• The battery pack is always discharging a little even when not in use Thus, the battery should be
charged before each use
• It the terminals (metal parts on the back! are dirty, the battery capacity wilt be reduced. When the
terminals are dirty, or when the battery pack has not been used for a long time, attach and remove it
several times. This will improve the contact between the battery pack and the video recorder/monitor
Also, wipe the ♦ and - terminals with a soft cloth or paper
• If the battery pack is not used fqr a long time (about 1 year) and you charge it again, the battery capacity
will be reduced. After several charging and discharging cycles, the battery will recover its onginal
capacity.
How to UM the switch on the battery pack
Use this switch as a reminder of charging.
Set the switch to the no-marked position when the charging is completed
Set the switch to the red-marked position when the battery is discharged.
Battery life
A battery can be fully charged and discharged about 500 in
lights up just after turning on the video recorder/monitor, ev
been instailed, replace the battery pack with a new one
Best temperature for charging
A lower temperature requires a longer charging time.
Charging under a temperature ranging from IC'D to 30°C (50°F to S6°F) is recommended.
Why a battery pack heats up
While a battery pack Is being charged or used, the chemical change occurring inside the battery pack
release heat. The
battery pack becomes warm, but this Is normal anO not dangerous.
Warning
If the and • terminals are short-circuited with a piece of metal, the battery heats up abnormally. This
IS very dangerous. Never put an uncovered battery pack m a pocket together with a key holder or
other metals
