Protocol
When the VL-1000 is initially turned on, it
enters a “S
ELF
-T
EST
” mode, in which the
amplifier’s microprocessor checks various as-
pects of its control signals and supply voltages.
If the amplifier’s self-test routine is success-
fully completed, the following display will be
shown:
Operation
Metering
An extensive array of metering selections
are available to the owner of the VL-1000.
Pressing the DISPLAY SELECT switch allows
you to choose from among these options.
There are also two “Display Memory” switches
on the front panel of the VL-1000, which you
may use to store and recall your most-used
metering choices. To store a meter selection,
press
and hold in for ½ second the DISPLAY
1 (or DISPLAY 2) switch until you hear a double
beep. To recall the saved setting, just
touch
(momentarily) the DISPLAY 1 (or DISPLAY
2) switch.
