Tips for Avoiding the Spread of Viruses & Bacteria with Shared NK Equipment

We have been asked what is the best way to help prevent potential cross-contamination when using NK Equipment. While NK is not claiming these techniques will be 100% effective against a virus spreading, here are a couple of ideas that may help.

1) When sharing microphones, purchasing a set of finger cots to put on the end of the microphone creates a barrier between the mic and the user's mouth. The finger cot should not affect the overall sound amplification and can be removed after use and then a new one reapplied for the next user. They can be found online or even at your local Walgreens.

2) Use a 10% Bleach and 90% water solution to sanitize all the equipment. This solution is very effective against killing all types of viruses and should not harm the plastics or rubber used in our equipment.

Troubleshooting Power Issues with SpeedCoach Red/Gold or Strokecoach   (Size: 570.1 KB)

This is a quick guide on what to look for if you changed batteries and the power no longer comes on with your SpeedCoach Red or Gold or Strokecoach.

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.

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.

To answer this question, we created the chart below to show all of the features of the StrokeCoach, the SpeedCoach GPS, and the SpeedCoach GPS with the additional Training Pack. Make sure that you consider not only where you are in your rowing needs, but where you eventually want to be and what will be required to get there.
