too high. This can be avoided in night mode.
In night mode, when the screen brightness adjusted according to the ambient brightness collected by the light
sensor is higher than the set maximum brightness for night mode, the system will adjust the screen brightness
to the maximum brightness for night mode, otherwise, the system will automatically adjust the screen
brightness according to the brightness mapping table.

Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient
temperature of the rack environment may be greater than room ambient. Therefore, consideration should
be given to installing the equipment in an environment compatible with the maximum ambient temperature
(Tma) specified by the manufacturer.
Reduced Air Flow – Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
Mechanical Loading – Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
Circuit Overloading – Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of the circuits might have on overcurrent protection and supply
wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this
concern.
Reliable Earthing – Reliable earthing of rack-mounted equipment should be maintained. Particular
attention should be given to supply connections other than direct connections to the branch circuit (e.g.
use of power strips).
