3.4.9 Battery
Charging
Prior to doing any testing, charge the Cellcorder for at least eight hours to
guarantee six hours of battery operation. The front panel CHARGE light
indicates charging only and does not indicate when the battery is fully
charged.
The batteries are lead acid cells and do not exhibit the memory problems
associated with nickel cadmium type batteries. If the batteries wear down
during testing, plug in the charger module and keep testing.
If the battery has been overdischarged, charge the unit for 15 to 30 minutes
prior to using it plugged in to AC. The life of the battery is directly related to
how well it is charged. Do not store the Cellcorder in a discharged condition.
(Refer to
Application Note CC-003
.)
During use, the unit indicates when the battery is near a discharged state by
beeping four times and displaying the following:
_ _ _ * WARNING * _ _ _
Cellcorder
BATTERY LOW
-RECHARGE-
In this state, when any key is pressed, the Cellcorder returns to the Main
Menu. This message appears once a minute for five minutes, then the unit
powers itself off. All data will remain in memory and can be recovered after
the battery is recharged. If the unit is powered on without being recharged, it
will shut down without warning after one minute. If you continue to use the
Cellcorder in this state, unpredictable results may occur and data storage
could be affected.
To conserve battery life, the Cellcorder automatically shuts down if
unattended for more than eight minutes.
