About High Temperature Mode
This computer has a high temperature mode function that prevents the degradation of
the battery in high temperature environments.
We recommend setting the high temperature mode function when installing the com-
puter in a car, etc. To do this, set [Environment] in [Main] menu of the Setup Utility to
[High Temperature]. Note that a 100% remaining battery reading in [High Temperature]
mode is about an 80% reading in [Normal Temperature] mode.
After switching from [Normal Temperature] to [High Temperature], or vice versa, the
remaining battery will not be displayed properly until the battery pack is completely
discharged or fully charged.
Set the value for [Critical battery alarm] to 5% or more. This is necessary for the
standby or hibernation function to be completed (assuring data is saved) when
the battery level is low.
When making a setting for [When the alarm goes off, the computer will] in [Alarms]
- [Alarm Action], add a check mark for [Force stand by or shutdown even if a
program stops responding.]
