Should the system “get stuck“ (evident from the fact that input is no long-
er possible), you can perform a reset. On the underside of the device you
will find a small hole marked RESET. Press the button in this hole using
the stylus. SIMpad is restarted. If a simple reset does not clear the fault,
please refer to “Troubleshooting“
, see page 92.
After a reset you are requested to enter the calibration, date and time
again.

When the SIMpad is AC-powered, there is no load on the built-in battery.
If it is not at full capacity, it is charged up automatically.
If the battery is fully discharged,

can see that the device is charging when the orange LED on the right side
of the screen is lit. After approximately 1.5 hours about 70% of charge ca-
pacity is reached.
As soon as you use SIMpad without a connection to AC power it draws
its power from the battery. When the battery is fully charged you can use

ing on communication with other devices and on the screen brightness
set). You should therefore minimize the screen brightness as far as possi-
ble (see page 80 for adjusting brightness).
When the charge capacity of the battery drops below 20% an appropriate
warning is displayed on the screen. When the charge capacity drops be-
low 10% you should recharge the device.
When SIMpad is switched off and not connected to AC power, your data
is retained for around
 GD\V with a fully charged battery.
Consider backing up your important data (see page 79) or trans-
ferring it to a PC (see page 26) if you are not going to use SIMpad
for an extended period of time and it is not connected to AC pow-
er.
