Lee Valley Tools SunCalc AB906 Instructions

Sunlight Calculator (SunCalc®)
(AB906)
The following instructions were provided by the manufacturer.
1) To assemble the SunCalc, insert the stake into the opening on the underside of
the unit. Tighten the pieces firmly together.
2) Select a day when you can reasonably expect a full day of sunlight with limited of
no clouds.
3) Start early in the day, between 7 and 9 A.M. Place the SunCalc as close as
possible to your specific planting location. We recommend the unit be placed in a
flower pot filled with soil to avoid shade created by other nearby plants. It can also
be placed directly in the ground. Make sure the face of the unit is parallel to the
ground so the SunCalc measures the sun's rays in the same way the plant's leaves
receive the sun.
4) Press the on/off button on the face of the SunCalc. The four small LED lights next
to the various sunlight levels will flash every few seconds; this indicates the unit is
taking sunlight readings.
5) After 12 hours of continuous operation, the SunCalc will complete taking sunlight
readings. A single LED will light up to indicate the light level measured in that
location as Full Sun, Partial Sun, Partial Shade, or Full Shade.
6) After noting the test results, press the on/off button to turn off the SunCalc.
(It will automatically shut itself off after about 24 hours.)
If the SunCalc appears to malfunction for any reason, turn the unit off. Open the
SunCalc by removing the three small screws on the underside of the unit. Lift off and
turn over the top of the SunCalc. Remove the batteries; wait 10 seconds; reinstall.
Re-align the top of the SunCalc with the base. Replace and tighten the screws;
restart by pressing the on/off button. If after restarting, the unit continues to
malfunction, replace the batteries with fresh, new batteries.
Use only fresh alkaline button cell batteries: A76/LR44/AG13/L1154.
Do not mix old and new batteries.
Batteries must be installed in the correct direction and polarity.
Clean the battery contacts prior to installing batteries.
Dispose of batteries safely and in accordance with local laws.
Keep all button cell batteries away from children.
