The CF-H2 was developed based on extensive research
into the real-world portable computing environments. Pur-
suit of usability and reliability under harsh conditions led
to innovations such as the use of magnesium alloy, vibra-
tion damped hard disk drive, exible internal connections.
The CF-H2’s outstanding engineering has been tested
using the strict MIL-STD- 810F (for vibration and shock)
and IP (for dust and water) based procedures.
As with any portable computer device precautions should
be taken to avoid any damage. The following usage and
handling procedures are recommended.
Before putting the computer away, be sure to wipe off
any moisture.
 NOTE
l
The battery pack may become warm during recharg-
ing or normal use. This is completely normal.
l
Recharging will not commence if internal temperature
of the battery pack is outside of the allowable temper-
ature range (0 °C to 50 °C {32 °F to 122 °F}).
(
è
Reference Manual “Battery Power”) Once the
allowable range requirement is satised, charging
begins automatically. Note that the recharging time
varies based on the usage conditions. (Recharging
takes longer than usual when the temperature is 10 °C
{50 °F} or below.)
l
If the temperature is low, the operating time is short-
ened. Only use the computer within the allowable
temperature range.
l
This computer has a high temperature mode function
that prevents the degradation of the battery in high
temperature environments. (
è
Reference Manual
“Battery Power”) A level corresponding to a 100%
charge for high temperature mode is approximately
equivalent to an 80% charge level for normal tempera-
ture mode.
l
The battery pack is a consumable item. If the amount
of time the computer can be run by using a particular
battery pack becomes dramatically shorter and re-
peated recharging does not restore its performance,
the battery pack should be replaced with a new one.
l
When transporting a spare battery inside a package,
briefcase, etc., it is recommended that it be placed in
a plastic bag so that its contacts are protected.
l
Always power off the computer when it is not in use.
Leaving the computer on when the AC adaptor is not
connected will exhaust the remaining battery capacity.
