5.2 X-SUS Circuit Board Removal/Installation Procedure
When removing the circuit board after the main power is turned on/off, wait for at
least four minutes 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.

To release the lock, release it by gently flipping it with the nail of the
thumb or forefinger. Never pinch the lock lever with fingers or hook
on it (especially with a fingernail). Doing so might damage the lock
