Battery compartment
The VSP-8000 is equipped with a lithium battery for backing up
the internal clock of the unit. The battery is charged when power
is supplied to the unit. After 30 hours of charging, the battery is
capable of maintaining the clock operation for up to 30 days.
Note: If power is supplied to the unit for only a short period of
time, the battery may run out of power and cause the
clock to be incorrect.
Battery life
With the AC adapter unplugged from the wall socket, wait
approximately one hour and then turn on the power and check
the initial screen. If the screen shown below appears, then the
battery has expired. At this point, replace it with a new battery.
