== NVRAM Battery == The TT030 uses a Motorola MC146818A real-time clock with battery-backed NVRAM. The backup battery (typically a 3.6V lithium cell) will eventually expire and should be replaced proactively to prevent NVRAM data loss and clock reset. * Check the battery voltage with a multimeter. Replace if below 3.0V. * Replacement: CR2032 with holder (if modifying from the original soldered cell) or equivalent 3.6V lithium cell. * Expired batteries can leak and damage nearby PCB traces.
