Speed switches (SS200 and SS300) require the installer to input the number of "teeth" on the gear that the pickup is using to measure RPM. If the number of teeth is not known, use this procedure to calculate it:

1. Set TEETH = 60 on the SS200 or SS300.
2. Operate the equipment at a known RPM, using the engine tach or other RPM measurement tool.
3. Multiply the SS200 or SS300 RPM reading by 60 and divide the total by the actual engine RPM.
4. Enter the new calculated value for TEETH setting.
