Charging the batteries
The AC adapter supplies electricity to the Minicom IV and charges
the built-in batteries. Leaving the AC adapter plugged in will not
harm the Minicom IV or the batteries.
The first time you set up your Minicom IV, leave the AC adapter
plugged in for 24 hours to charge the batteries. You can use the
Minicom IV at the same time.
Checking the batteries
The batteries lose their ability to hold a full charge if you keep the
Minicom IV 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 Minicom IV 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
Minicom IV. If the power light blinks within 30 minutes,
exercise the batteries.
Exercising the batteries
1.Leave the Minicom IV on with the AC adapter unplugged until
the power light flashes.
2.Plug in the AC adapter for 24 hours. (You can use the Minicom IV
for calls during this time.)
3.Unplug the AC adapter and leave the Minicom IV on for
30 minutes.
4.Repeat steps 1 to 3 until the power light glows steadily after
30 minutes without the AC adapter.
