NOTE

• Even if “BLACKOUT” is on, the [POWER], [ALERT], [PROTECT], and [LIMIT] indicators light

as usual.

• Even if “BLACKOUT” is off, for protection of the display, if there is no operation for one min-

ute, the display automatically darkens; if unoperated for 20 minutes, it automatically turns off.

To turn on the display again, simply press any key on the front panel or rotate any knob.

NOTE

• Refer to “Panel Operation” – “Panel lock” (page 14) for instructions on releasing the panel

lock.

• If a PIN code has been set, the PIN code must be entered even when the setting of the panel

lock is changed “OFF” to “LCD” or “ALL.”

NOTE

• If you have forgotten the PIN code, you will need to initialize the device to release the PIN

code. Refer to “Initializing the PX amplifier” (page 37) for instructions on initializing.

• In the initialized state, the PIN code is set to “0000.” When the PIN code is set to “0000,” the

PIN code input is not needed to release the panel lock.
