A) By-pass orifice in diaphragm is clogged with dirt or debris, or by-pass is clogged by an invisible gelatinous film due to "overtreated" water.
A) Remove inside parts assembly and wash under running water. NOTE: size of orifice in by-pass is of utmost importance for the proper metering of water by the valve. Equiparts recommends that you do not enlarge or damage this orifice. Replace inside parts assembly if cleaning does not correct the problem.

Remove and then reinstall battery compartment door to activate 10 minute flashing range indicator feature. The range potentiometer is located at the top of the electronic sensor module beneath a rubber plug. Using the small screwdriver provided, turn the potentiometer a few degrees. Turn clockwise to increase range, turn counterclockwise to decrease range. Place cover over sensor module, position body into typical user range and check range by looking for red flashing light. Red light should only flash when picking up user. Repeat adjustment procedure until desired range is obtained. Reinstall optima plus. Refer to optima plus installation manual for greater detail on range adjustment procedures.
When Optima Plus has approximately 4000 flushes left, the same red light that appears at start-up will flash four times quickly whenever an object is detected. When this occurs, we recommend changing the batteries.
DO NOT use abrasive or chemical cleaners to clean the Optima Plus, they may dull the luster and attack the Plastic Cover and the chrome finish of the flushometer. Use only soap and water, then wipe dry with clean cloth or towel. While cleaning the bathroom tile, the Optima Plus should be protected from any spattering of cleaner. Acids and cleaning fluids can discolor or remove chrome plating.
