The TCU coin cell battery is located behind the rubber seal on the front of the TCU. To access the battery
compartment you will need to remove the TCU from the bicycle (Fig. 7.7 A).
To replace the CR 1620 coin cell battery, use tweezers to pull the battery out. When installing a new battery, make
sure it is fully inserted (Fig. 7.7 B).

WARNING: Do not use metallic tweezers to re-insert the battery as this will lead to the battery
short circuiting.
