How to Activate LCD Using the Light Sensor
The light sensor is recessed under the small round hole near the center of the dial
face. The hole is marked with a flashlight graphic (see figure). The light sensor
activates the LCD display for several minutes when the unit is exposed to a light
source. For example, a unit mounted in an inside location would turn on the LCD
for several minutes after the room light is turned on. A unit mounted in an outside
pit would turn on the LCD for several minutes after the pit lid is opened exposing
the unit to daylight. If the LCD is currently off, the LCD may be reactivated by covering
the dial plate with your hand for about two seconds. In bright sunlight, it may
be necessary to close the cover or the pit lid momentarily. If the LCD does not reactivate
as expected, try shining a flashlight on the light sensor.
