Service cautions and disassembly

MP-C33DE-BU

Before disassembly or assembly

Perform the following operations before disassembling the unit.

Disconnect the AC power adapter.

Remove the lithium ion battery pack.

These operations shut off the power supply to the circuit boards and turn the unit completely off. If these operations are not done, connectors could be connected or disconnected while power is being supplied to the internal circuitry and a malfunction such as the impossibility of turning the unit on would result.

Be careful not to damage the connectors when connecting or disconnecting wires.
