The Display/Power button on the VK-R3 remote control provides two functions: turning the VK-50
display ON/OFF and switching the power to the preamplifier.
To control the display:
Pressing the display button will switch the display from ON to OFF and back.
Turning the VK-50 OFF
With the display in ON state, press and hold the Display button on the VK-R3 remote
control. This function is disabled when the unit’s display is turned OFF.
Turning the VK-50 ON
With the VK-50 in its OFF or STANDBY state, simply press the POWER button on the
VK-R3 remote control transmitter.
Fuse Protection:
A blown fuse in the VK-50 is an indication of a serious problem. If a replacement fuse fails as
well, no further attempts should be undertaken. Please contact the factory for professional service.
The proper fuse ratings are as follows:
For 100-120 VAC Units: 2A 250V Slow Blow
For 200-240 VAC Units: 1.5A 250V Slow Blow
Factory supplied fuses should be only replaced with the same type and rating parts.
Servicing
The Balanced Audio Technology VK-50 should require no service in normal operation. Please
direct any further service inquiries to the factory.
Cleaning
To remove dust, occasionally wipe the front and top surfaces of your VK-50 with a damp soft cloth.
If fingerprints appear, you may use a mild, non-alkaline soap solution. Do not use abrasive
cleaners, as they may damage the fine finish of the unit.
