RESET. To reset press both buttons when either Trip Distance, Average Speed, Ride Time, or

Maximum Speed is displayed. All of these functions reset together. When Ride Time reaches 10
hours, Trip Distance, Average Speed, and Ride Time reset automatically. Reset before starting
each ride to avoid automatic reset.
Trip Distance, Average Speed, Ride Time, and Maximum Speed reset together
RESET by pressing both buttons

RESET / POWER SAVER

PRESSING THE RIGHT BUTTON

Displays Speed with the other main functions: Total Distance, Trip
Distance, Average Speed, Ride Time, and Maximum Speed
Selects miles or kilometers and changes the calibration number in setup

PRESSING THE LEFT BUTTON

Moves from one digit to the next in calibration

PRESSING BOTH BUTTONS

Resets Trip Distance, Average Speed, Ride Time, and Maximum Speed
(all together) when any of these functions is displayed
Shows the calibration number when total distance is displayed

HOLDING BOTH BUTTONS

Reaches wheel-size calibration. First press both buttons in the Total
Distance function to display the calibration number. Then press
both buttons again to reach calibration.

BUTTONS

ment has been detected for 6 minutes, the display will go blank. Power consumption is re-

FUNCTIONS

OPERATION. Press the right button to move from one function to the next.

SPEED (displayed in all functions). Speed resolution is to 0.1 mph up to 19.9 mph, 0.5

mph from 20 to 39.5 mph, and 1.0 mph above 40 mph. ‘mi’ flashes when the Cyclometer is
receiving speed and distance data from the wheel sensor..
1. TOTAL DISTANCE–D. Accumulates the total distance (D) you have ridden up to 6,209.9
miles. At 6,210 miles it clears to 0 and resumes accumulation. To record yearly mileage, clear
before your first ride of a new year.
2. TRIP DISTANCE–d. Displays the distance (d) ridden since the last reset up to 620.99
miles. At 621.00 miles it resets to 0 and resumes accumulation. Trip Distance also resets auto-
matically when Ride Time reaches 10 hours. Reset at the start of each ride to avoid automatic
reset during your ride.

3. AVERAGE SPEED–AV. Displays the average speed since the last reset. Averages speed for

up to 10 hours. After 10 hours the Cyclometer 15 displays an ‘E’ instead of average speed. The
time over which the average has been calculated is shown in the Ride Time function.
4. RIDE TIME–ST. Displays ride times up to 9 hours 59 minutes. Resets automatically at 10
hours. Trip Distance and Average Speed also reset at 10 hours. Ride time is the time that the
bicycle's wheels have been turning. Time stopped is not accumulated. Average speed equals the
trip distance divided by the ride time.
5. MAXIMUM SP EED-MX. Displays the max speed since the last reset up to 75.0 mph.
