Fail-SafeINFOID:0000000006216226
When the ambiance temperature becomes extremely low or extremely high, AV control unit displays the mes-
sage and limits the AV control unit function.
FAIL-SAFE CONDITIONS
When the ambiance temperature is −20 °C ( −4 °F) or lower, or when it is 70 °C (158 °F) or higher
Display
The messages displayed on fail-safe conditions are as shown below:
DESCRIPTION OF CONTROLS
Ability Operation Mode
There is an ability operation mode for Fail-safes due to low or high ambiance temperature.
If HDD data can be read, fail-safe is shown, then normal displays are displayed only for functions which can be
operated.
RELEASE CONDITIONS OF FAIL-SAFE
Fail-safe is released on following conditions and normal mode is restored.
When The Temperature of HDD Is Low or High
If the ambient temperature becomes out of fa il-safe condition range, normal mode is restored.
