CALIBRATION
Change the blinking
digit of the calibration number with the right button
MILES OR KILOMETERS. When you install the battery, the Cy- clometer displays “SEL” and “km” flashes. You can choose whether miles or kilometers will be displayed by pressing the right button. After you have made your selection, press the left button to go to wheel size calibration.
If you want to switch between miles and kilometers after initial setup, you must remove the battery. When you do this, stored data us lost and the calibration number is reset to 2155.
CALIBRATION. “Cir” is on the top display and the right digit of the calibration number flashes on the lower display. Find the cali- bration number that matches your tire size from the table, or mea- sure tire circumference by the precise calibration method. Adjust the flashing digit with the right button, then press the left button to go to the next digit. When all the digits are adjusted, press the left button to exit.
You can also change the calibration number without removing the battery. In the Total Distance function (D) press both buttons to display the calibration number. Then hold both buttons down for to enter calibration. Set the calibration number as described above.
CALIBRATION NUMBERS. The calibration number is wheel circumference in milli- meters. This table is based on popular tire brands and assumes recommended inflation pressure and a rider weight of 165 lbs. (75 kg). To account for your unique combination of weight, tire pressure, and tire model, measure your tire circumference.

Calibration number equals tire circumference in inches multiplied by 25.4, or in millimeters.
PRECISE CALIBRATION. For the most precise calibration of your Cyclometer, measure the tire's ‘rolling circumference’ by the following method: Inflate your tires to your usual riding pressure. Mark the ground under the valve stem when the stem is at its lowest point. Get on the bicycle and have a helper push you in your normal riding position until the valve stem returns to its lowest point. Take care that the tire travels in a straight line. Mark below the stem again, then measure the distance between the marks in inches or millime- ters. If you measure in inches, multiply your measurement by 25.4 to convert to millime- ters. The calibration number is the tire circumference in millimeters.
INSTALLATION
STEP 1 – TRANSMITTER. Position the magnet housing over a pair of crossed spokes with the spokes inside the slots. Insert the mag- net in the well and close the housing pressing the parts together until they lock together over the spokes.

STEP 2– RECEIVER. Position the receiver on the right fork blade opposite the magnet. Insert a zip tie through the slot and secure it loosely on the fork. Rotate the wheel until the transmitter is behind the receiver, then adjust the receiver on the fork so that it is opposite the magnet. Rotate the receiver until it is 1/8 to 3/16" from the transmitter magnet then tighten the tie and trim off its free end with scissors.
STEP 3 - RECEIVER WIRE. Attach the wire to the inside of the fork with cable ties, then wrap the wire around the front brake cable until the ex- cess has been used up. Attach the wire only to parts that rotate when the bicycle is
Brake Cable
STEP 4 – MOUNT BRACKET. Wrap the rub- ber shim around the handlebar near the stem. Re- move the clamp screw and place the bracket on the handlebar over the shim. If the shim is too long, trim it shorter with scissors. Insert the clamp screw and tighten it until the bracket is secure. Slide the Cyclometer into the bracket from front to rear until it snaps on. Spin the wheel and confirm that a speed reading is displayed. If the display remains at zero, check that the receiver and transmitter magnet are

BATTERY & TROUBLESHOOTING
AVOCET 1-YEAR LIMITED WARRANTY
INSTALLING A NEW BATTERY. Re- move the battery by prying up the cap with a screwdriver. Install the new battery with its positive (+) side toward the cap, then press in the cap. Use only an Avocet Cyclometer 15 battery or equivalent (see specifications). Af- ter battery installation a blinking “km” appears on the display. Press the left button for “mi”. Press the right button to calibrate. The default calibration number 2155 will appear. Any num- ber other than 2155 indicates improper reset, and the battery must be removed then reinstalled after waiting at least 10 minutes.
TROUBLESHOOTING
Speed and distance seem too high or too low
Check calibration number
Confirm calibration number by tire roll- out
Check spacing between receiver and transmitter
No speed or distance
Check transmitter/receiver alignment and spacing
Check contacts on back of Cyclometer and on mount and clean with a pencil eraser if necessary
Check for broken wire
No display or display dim
Replace battery
Incorrect data or unusual display Remove battery, then reinstall after
15 secondss
