Bell Wireless Bike Computer – Generic Manual
BATTERY Installation
Make sure to write down the Odometer value before changing the battery so you can later re-enter it in the odometer. Install the new battery with the positive ( ) pole facing outward. After changing the battery
all settings are erased.
Clamp the magnet to a spoke on the right side of the front wheel. Make sure that the magnet is facing the outside of the wheel so that the flat side of the magnet passes in front of the sensor.
Attach the speedometer sensor to the right fork leg using the two cable ties provided. Make sure the metal side of the sensor is facing the wheel. Do not fully secure the cable ties yet, as the sensor location might require further
adjustments.
Adjust the sensor and magnet location so that clearance between the two is no greater than 1/5" (5mm). Magnet should pass by the tip of the sensor. Remove the adhesive tape shield on the back of the bracket and position the bracket on the handlebar of the bicycle. Fasten the O-ring around the top edge of the bracket and wrap around the underside of the handlebar and attach to the bottom edge of the bracket. Insert the
computer into the mounting bracket and twist to the right to lock into place.

the correct digit. Repeat until all four digits are entered.

The F12-F20 series are pretty much the same. The wireless instructions work but the buttons are different. The wired models have a left/right button/rocker selector at the bottom and it may look like a one piece plastic button but it's not. Pressing both sides for a few seconds will reset the computer. The computer will show the default '2124' tire size, with the '4' blinking. Pressing the right button will change the number. Press the left button when finished and the number to the left will blink and you set that one and so forth. After the tire size/number is set, the KM will blink and you can change that to MPH with the right button and press the left button when finished and the clock setting will come up. You can choose 24 hr (military time) or 12 hour (no am/pm option) and the numbers/time will show the hours first then minutes.

I have set all my computer up easily but when it comes to age and weight, I am not sure if the weight is in ibs. Can anyone help me on this. I have a fat burned programme aswell but so far it has not registered any fat burnt yet, does anyone know why. Could it be to do with the age and weight function.
I would be grateful if someone is able to tell me how to set the weight - thanks so much
