Verifying the i3822V and iPSU Installations
Note:
A faulty battery is indicated if the BATTERY indicator does not light green
within five minutes (assuming the iPSU is plugged into a functioning AC power
outlet).
6. Secure the battery with the safety strap.
7. Place the housing cover over the unit and press gently on it until it snaps into
place.
8. Fasten the cover with the screws you removed earlier.
iPSU maintenance
The iPSU needs no maintenance other than regular battery inspection and
replacement. If the power supply unit is equipped with a backup battery, it continues to
provide power to the i3822V during a power outage so that a phone call can be made
in the event of an emergency. During a temporary AC power outage, the iPSU power
source is switched to the battery without interruption of services. When the AC power
is restored, the iPSU power source is switched back to AC power. The switchover
between the AC power and the battery is automatic and instantaneous.
Note:
Reserve the battery charge during a power outage. Do not access the Internet
when the power is running on the battery. Doing so will discharge the battery at a
much faster rate and shorten the voice service time.
You are solely responsible for periodically replacing this battery to provide
uninterrupted voice services during a power outage. Your service provider does not
monitor the battery and is not responsible for its replacement.
