How to charge the battery
Use only the AC Adapter or vehicle charger supplied with your Itronix fex21.
Plug the fex21 Charging Adapter into the COM1 D-type connector, as shown in the
diagram. Plug the output lead into the power port of the Charging Adapter and then
connect the AC Adapter to a suitable AC mains power supply.
The battery pack may take up to three hours to recharge. Make sure that the
battery pack is fully recharged to 100% capacity, so that the battery power
calculations will be accurate.
The charging status is shown by an orange LED in the IR window on the lower
right-hand side of the fex21 case. The LED will flash regularly while charging is in
progress. The LED will light continuously when charging is complete. If the LED
flashes irregularly, a charging error has occurred, and you should seek advice from
your system provider.
NOTE: The fex21 battery will not recharge when the computer is in suspend mode.
Switch the fex21 on before connecting the AC Adapter.
Using the Itronix fex21 Offline Battery Charger is an ideal way to recharge your
fex21 battery packs without using your fex21. Refer to the Offline Battery Charger
manual for details.

Using your fex21 safely
Your Itronix fex21 has been ergonomically designed for comfortable and safe use.
However, as with all equipment, you should pay attention to good working
practices while using it.
Some people may experience discomfort while using computers. If ignored, this
discomfort may sometimes lead to Repetitive Strain Injury (RSI), which is also
known as cumulative trauma disorder or repetitive motion injury. You can minimize
the risk by following these guidelines:
•
Pay attention to your posture. Keep your fingers and body relaxed whenever
possible.
•
Avoid keeping your muscles tense for long periods. Change your tasks often to
avoid prolonging muscle strain. Support the fex21 while you are using it.
•
Reduce eyestrain by adjusting the backlight and contrast settings properly for
your working environment. Look away from the screen periodically and focus
your eyes on distant objects. Have your eyes checked regularly.
•
Take frequent short breaks. Use these breaks to exercise the muscles in your
hands, arms, shoulders, neck and back.
If your fex21 is fitted with a radio transmitter, you should also read the radio safety
statements in the “Using Wireless Communications” section of this manual.
Backstrap
The Itronix fex21 is supplied pre-fitted with a backstrap, allowing it to be carried
easily and securely with one hand. This low-profile strap is designed so that you
can exchange battery packs without removing it.
By default, the strap is fitted for holding the fex21 in your left hand and operating it
with your right. If you wish to use your fex21 left-handed, remove the securing
screws, then replace the backstrap in the new position, using the other pair of
screw-holes.
Replacement backstraps and securing screws are available from your system
provider.
CAUTION: Only fit the supplied securing screws into the backstrap
screw-holes. Itronix does not recommend the use of other screws, or the use
of these holes to secure the fex21 to any fixed object, as the screw-hole
threads and fex21 may be damaged.
