Note: If you adjust the rate and the next increment exceeds the maximum or minimum flash rate, the display does not increment.
Do one of the following:
- With the power on, slowly turn the tuning knob counterclockwise to increase the flash rate, or clockwise to decrease the flash rate. The tuning knob is sensitive. Each "click" is equal to 0.01 FPM.
- Quickly turn the tuning knob or use the x2 or ÷2 buttons to change the FPM by larger increments.
