5.36 Key Lock
Function : The key lock switches ON / OFF
Format : Integer KL
Explanation : The command enables/disables the remote control and access
through the front panel. The default value is 0 (OFF) thus the player is
unlocked.
If the key lock switch is set to 1, all buttons (front panel and remote control)
including the external switch control, mouse control and power control are
disabled. Use this setting for a PC-controlled player to lessen interference
from outside sources such as remote controls.
If the key lock switch is set to 2, only the tray open button/key is disabled and
the OP command no longer controls the tray. Thus, after powering OFF the
player, the locked tray protects the disc from unauthorized personnel.
