PROBLEM
POSSIBLE SOLUTION
No stroke rate readings

The display unit may not be in contact with the mounting bracket. Push the display unit firmly onto the mounting bracket until a loud ‘click’ is heard.

The seat magnet may not be passing close enough to the stroke rate sensor. Make sure that the magnet is passing directly over the black sensor and within 3/4".

The magnet and stroke rate sensor may not be correctly aligned. Make sure that the magnet and black sensor are both across (perpendicular to) the long axis of the boat.

If possible, swap your control unit with a control unit you know works. If the stroke rate begins working, your problem lies with your control unit. If the stroke rate still does not work, your problem lies with your mounting bracket, stroke rate sensor or magnet.

Timer does not start The unit is in STOP or MEMORY mode. Hold the NOT START button for two seconds to reset the unit and clear “STOP”. The unit may not be receiving a “start” signal from the stroke rate sensor. Review “no stroke rate” solutions above.
Display appears faint,
display suddenly goes blank,
and/or unit will not turn on

Replace your battery (CR2032 Lithium watch battery), following the instructions on page 10. In rare cases, an electrostatic discharge (static electricity “shock”) may cause your display’s unit to go blank. In dry weather, a charge can build up while the unit is being carried in the storage pouch or a pocket and be discharged when the unit is touched or placed on the mounting bracket. If this happens, you can perform a complete reset of your unit as follows:

Open the battery door and remove the battery. Leave the battery out for at least 10 seconds while pressing and holding the button. Release the button and reinstall the battery. The unit should turn on and function normally when you push the button.

If this procedure does not solve the problem, and your unit is more than 2 years old, try replacing the battery.
