Rechargeable battery packs
Battery pack care
• Remove the battery pack from the video recorder/monitor after use, and keep it in a cool place. When
the battery pack is installed on a video recorder/monitor, a small amount of current flows to the recorder
even if the POWER switch is turned off. This causes overdischarge 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.
• If the terminals (metal parts on the back) are dirty, the battery capacity will 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 for 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 original
capacity.
How to use the switch on the battery pack
"\ Switch
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 times under nonnal temperatures. If “BATTERY”
appears just after turning on the recorder, even though a fully charged battery pack has been installed,
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 lO'^C to 30°C (S0°F to 86’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 and 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 in a pocket together with a key holder or
other metals.
