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 the [Main] menu of the Setup Utility to
[High temperature]. Note that a 100% remaining battery reading in the [High Tempera-
ture] mode is about an 80% reading in the [Normal Temperature] mode.
When using the wireless display in a high-temperature environment, be sure to set
the wireless display in the [High temperature] mode.
In this case, be sure to set [High Temperature] in the Setup Utility (computer side
setting) too. If this setting is not made, the following message will be displayed:
"Thermal environment option has been changed. - Need to restart the system now."
Press [OK] and restart the computer.
