Position the sensor using the wall mount, table stand, or
ground anchor options. For best results:
•
Place in a location with maximum exposure to
the sun.
•
Place the sensor away from electrical or mechanical
objects.
•
Place the sensor away from moisture.
•
Do not place the sensor more than 100 meters
(328 feet) from the main (indoor) unit.
•
Position the sensor so that it faces the main (indoor)
unit. Minimize obstructions such as doors, walls, and
furniture.
The sensor range is up to 100 meters (328 feet) with no
obstructions, but if the main unit has a shorter range than
the sensor, you may have to move the sensor closer for
reception. You may need to experiment with various
locations to get the best reception.
This icon will blink on the main unit UV value
display box when it searches for the sensor.
It stops blinking when the sensor has been found.
Once the batteries are in place, the sensor will
transmit signals every 40 seconds. It will take over an hour
before all measurements on the main unit are displayed
(e.g. UVI history) because some measurements are hourly
averages.
