Bontrager TRIP 4W User Manual

If the computer is giving erratic information, the battery may be running low. 
Replace the battery whenever the computer malfunctions, or every 6 months. 
When purchasing a new battery, it is best to take the old battery to the store with 
you. This is the battery type: CR2032, lithium cell, 3 volts.

When the battery is removed, the computer automatically resets function totals 
to zero. After installing a new battery, you can manually set your totals, but you 
must note those values before removing the battery.

A Reset erases all data and settings. Before a Reset, you may wish to record the 
total miles (or kilometers) of the odometer so you can set the odometer to this 
number later during set up.

Hold the Reset button (AC) for two seconds (Figure 11). A ball point pen 
works well for this. The button is on the back of the computer. 

Remove the computer from its base. Rotate the battery cover about one-
quarter turn in a counter-clockwise direction (Figure 9). A coin or flat head 
screwdriver works well for this.

Lift the battery cover, exposing the battery. Be careful to avoid losing the 
rubber O-ring seal.

Remove the old battery.

Insert the new battery with the ‘cross’ and identifying label pointing up 
(Figure 10).

Replace the battery cover with O-ring seal and rotate clockwise one-
quarter turn.
