Notes:
•

In the event of power failure, the event log and all of the settings will be saved, no matter
how long it takes to restore power.
Conditions for recharging the internal and external batteries
Note: You should perform a complete charge/discharge cycle for internal and external batteries
before use. Internal and external batteries reach optimal performance after three full charge/
discharge cycles.
If an external DC power supply (12–28 V DC / 15 A max) is in use, it must have enough charge to
supply power for at least one hour.
