About the batteries
The Superprint 4425 uses batteries when you unplug the AC adapter or
the power fails. Fully-charged, the six AA rechargeable NiCad batteries
will provide 45 to 60 minutes of normal use.
When the power light blinks, you have about 5 minutes of power left.
The batteries will last longer if you turn off the printer.
Checking the batteries
The batteries lose their ability to hold a full charge if you keep the
Superprint 4425 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 Superprint 4425 AC adapter.
2. Turn on the Superprint 4425 for 30 minutes. (You can still use it for
calls during this time).
3. The batteries are fine if the power light still glows steadily after 30
minutes. If the power light blinks within 30 minutes, exercise the
batteries.
4. Plug the Superprint 4425 AC adapter back in and turn off the unit.
Exercising the batteries
1. Leave the Superprint 4425 on with the Superprint 4425 AC adapter
unplugged until the power light flashes.
2. Turn the unit off and plug in the Superprint 4425 AC adapter for 24
hours (you can use the Superprint 4425 for calls during this time).
3. Unplug the Superprint 4425 AC adapter and leave the Superprint
4425 on for 30 minutes.
4. Repeat steps 1 to 3 until the power light glows steadily after 30
minutes without the AC adapter.
