Table 1. Temperature / Humidity Limits.

Tair is defined as ambient air temperature surrounding Monitor.

Note 1:

Tair < 32°C

: 95% RH maximum.

Tair > 32°C

: Absolute humidity content not to exceed 100% at 32oC.

Note 2:

Tair @ -20°C

< 48 hours

Tair @ 60°C

< 168 hours

Note 3: Slight background color changes are allowed depending on ambient temperature.

This phenomenon is reversible.

Note 4:

Tair @ -30°C

: 15% RH (exterior face of Vandal Shield)

Tair @ 54°C

: 100% RH (exterior face of Vandal Shield)

Note 5: Upper operating temperature limit of 60°C is without solar loading. See section 3.2

for operating temperature conditions with solar load.

Reference to "room ambient" is interpreted as 20°C - 25°C [68°F -? 77°F] and applies throughout

this specification unless otherwise noted.

Excluding the exterior face temperature range of the Vandal Shield (Note 4), this Monitor will not
be subjected to environments outside of the limits of Table 1.

For product reliability predictions, the assumed temperature profile is:

3.2 Solar Loading

The Monitor is useable in an environment consisting of a 50

C ambient air temperature and the

following input solar power.
