Sensitivity Adjustment

• Set the adjuster for stable Light ON area, minimizing the effect of the installation environment.

• Use the offered adjustment screwdriver. Do NOT turn with excessive force to prevent

product damage.

• The steps below are based on Light ON mode.

STEP Status

Description

Turn the adjuster from MIN to MAX sensitivity and

Received

check the position (A) where the operation indicator

activates under the light ON area.

Turn the adjuster from (A) to MAX and check the

position (B) where the operation indicator activates

Interrupted

under the light OFF area.

If the operation indicator does NOT activate at the

MAX (maximum sensitivity): MAX = (B).

Set the adjuster at the mid position between (A) and

(B) for optimal sensitivity.
