Before dismounting panels read notes below!

Caution when removing circuit board!

When removing the circuit board after the main power is turned on/off, wait for at least one minute before starting to remove the circuit board.

If the circuit board removal is started immediately after turning off the main power, it can result in electric shock or damage to the circuit due to residual electric charge.

Caution on handling the FPC connector!

To release the black lock lever of the connector, flip it up gently in the middle with the nail of the thumb or forefinger, from the side with the cable.

Never pinch the lock lever with fingers or tools. Doing so might damage the lock lever.
