The coin cell battery is located behind the rubber door on the front of the TCU. To access
the battery compartment, you need to remove the TCU from the bicycle.
To replace the CR 1620 coin cell battery, use non-metallic tweezers to pull the battery out.
When installing a new battery, make sure it is fully inserted.
The MasterMind TCU does not have an interchangeable battery. The battery is kept
charged via the main internal battery and will not need to be replaced.
The Micro-USB (TCU) or the USB-C (MasterMind TCU) port below the battery
port is for Authorized Specialized Retailer and Specialized Service Center
diagnostic use only. Please ensure the USB rubber door is always correctly
pressed in and firmly closed.
WARNING! Do not use metallic tweezers to re-insert the battery as this will
lead to the battery short-circuiting.
