IMX644 Owner’s Manual
Controls and Functions
1
[LOCK] Switch and Indicator
The [LOCK] switch can be used to “lock” the panel level knobs
(5, 8, and 11), making them inoperable and preventing acciden-
tal changes. After setting levels and/or recalling a memory as re-
quired, press the [LOCK] switch with a thin object (such as the
tip of a pen) to prevent further changes to the level settings. The
LOCK indicator lights red when the controls are locked.
Press the [LOCK] switch a second time to unlock the controls
and allow normal operation of the level knobs.
NOTE
• The LOCK buttons in the IMX644 Manager application
INPUT display can be used to enable independent operation
of each panel level control.
• If the settings of the level knobs have been increased since
the [LOCK] switch was engaged, the settings at the time the
[LOCK] switch was engaged will be retained when it is
disengaged. In order to increase a level setting after
disengaging the [LOCK] switch in such a case it is necessary
to lower the setting of the knob to the point at which it was
locked, and then raise the level as required.
• When the power is turned ON, the MEMORY number that
was active when the power was turned OFF is recalled. Save
the memory using the IMX644 Manager application before
engaging the [LOCK] switch.
• The LOCK function is temporarily disengaged when the
IMX644 Manager application goes online. The LOCK
function will be re-engaged if the unit is restarted, so don’t
operate the [LOCK] switch while the IMX644 Manager is
online.
