If a certain period of time elapses without any operation being

performed, the operating mode will be switched back to "Atten-

When muting turns on, the [MUTE] indicator of the selected

channel will lit.

When muting turns off, the [MUTE] indicator will go unlit.

When front panel lock is temporarily disabled, the [PANEL

LOCK] indicator will flash.

When front panel lock is enabled, the [PANEL LOCK] indicator

will lit. While the front panel is locked, "LC" is shown in the dis-

play.

Even if front panel lock is temporarily disabled, it will be

relocked when one minute passes without any operation being

performed or when the power is turned off.
