Ultratec Miniprint 425 - Manual (Page 33)

About the batteries
The Miniprint 425 runs on batteries when you unplug the AC
adapter or when the power fails. Fully charged, the 6 AA
rechargeable NiCad batteries will provide 45 to 60 minutes of
normal use.
When the power light blinks, you have about 5 minutes of
battery power left.The batteries will last longer if you turn off
the printer when you use battery power.
Checking the batteries
The batteries lose their ability to hold a full charge if you
keep the Miniprint 425 plugged in all the time. If you want to
be sure the batteries stay fully-charged, check them once a
month. Follow these steps to check the batteries:
1. Unplug the AC adapter.
2. Turn on the Miniprint 425 for 30 minutes. (You can still
use it for calls during this time).
3. If the power light glows steadily after 30 minutes, the
batteries are fine. Plug the AC adapter back in and turn off
the Miniprint 425. If the power light blinks within 30
minutes, exercise the batteries.
Exercising the batteries
1. Leave the Miniprint 425 on with the AC adapter
unplugged until the power light flashes.
2. Plug in the AC adapter for 24 hours. (You can use the
Miniprint 425 for calls during this time).
3. Unplug the AC adapter and leave the Miniprint 425 on for
30 minutes.
4. Repeat steps 1 to 3 until the power light glows steadily
after 30 minutes without the AC adapter.
