Introduction
Some components are expected to wear out over UNIT-4’s lifetime - main examples being batteries and speaker drivers. UNIT-4 has been designed to be disassembled with glue-free design by anyone with 2 screwdrivers and AIAIAI’s step by step repair guides. This will make sure your UNIT-4's will stay with you for as long as possible.
