DISPLAY Brightness Function
Changing the Display Brightness: The VK-51SE display can be dimmed or turned
completely OFF by simply pressing the DISPLAY button on your VK-R3 remote control
transmitter.
Each press will reduce the brightness of display and LED indicators in steps from full ON to
OFF, and then one press back to full ON. The LED indicators will dim but never turn
completely OFF. With the display OFF, issuing any remote control command that would
normally require a display change (i.e.: Volume, Input selection, Fade) will automatically
turn the display back ON.
MUTE Function:
The VK-51SE has two mute modes: manual and automatic. The blue LED above the Mute button
goes ON when the unit is in MUTE state. To MUTE the VK-51SE, depress the MUTE button
located on the right side of the front panel. Depressing this button again will return the unit to its
normal operation and turn the mute LED off.
When the unit is powered up it automatically self-mutes until the proper operating points of the
circuitry are reached. It will then automatically go into Play mode, provided the Mute function was
not activated (the blue Mute LED is Off).
Turning the VK-51SE OFF even for short time, will make the unit reset its power sequencing
circuit and mute its output. It will then require 50 seconds for the unit to become operational
again.
