The button board controls the user controls noted in Section 6.1 LCD Controller Board Controls It can be removed or mounted in another area after initial adjustments are made.

3 Environmental

3.1Temperature and Humidity

The LC1200R withstands operating and storage environmental conditions listed in Table 2.

Table 2

	General Operating	Shipping and Storage	Comments
Temperature	0°C to 60°C	-20°C to 60°C	Note 2,3,4,5
	[32°F to 140°F]	[-4°F to 140°F]
Relative	Note 1	Note 1	Without
Humidity			Condensation

Tair is defined as ambient air temperature surrounding the LC1200R.

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: High temperature operation assumes the use of an enclosure that properly directs the fan airflow

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

Reference to "room ambient" is interpreted as 20°C - 25°C [68°F°-77°F] and applies throughout this specification unless otherwise noted.

For product reliability predictions, the assumed temperature profile is:
