Safety and power state

Use the power state listed for each procedure. Do not apply one procedure's power instructions to another: the inspection uses both powered and unpowered stages, and the voltage check requires the clock to remain on.

Power off & unplugged Power on Mixed: follow each step

General handling

  • Place the clock on a flat, stable surface before beginning any inspection or repair.
  • Keep hardware together.
  • When disconnecting components or wires, always grip the connector itself rather than pulling on the wire. Yanking or tugging on the cable can damage the wire or connector.

Stop and contact support if

  • A component has been replaced and the issue is still not resolved.
  • A connector, wire, or terminal appears damaged.
