When the AC adapter and the battery are used simultaneously, the AC adapter is used
at higher priority. If the AC power supply is cut off such when a power failure occurs,
the MV1000 automatically switches to battery operation. When the AC power supply
recovers, the MV1000 returns to AC adapter operation. If you are using the battery as
backup power, fully charge the battery before using it.
