Operation of the VS-20
Upon power-up, the device performs a self-test and selects the last displayed channel (also recalls the compensation level
that was used for that channel.
Select input channels simply by pressing the following key sequence on the keypad:
Single or Double digit input channel number, followed by ENTER
For example, to select input #12 punch
: 12e
When selecting a channel the keys, you have 5 seconds to hit enter or the operation is automatically cancelled. So if you
stop for more than 5 seconds, the keypad automatically resets itself. Also, if you press a key that is unexpected (such as
Esc or *) or if the channel is out of range, it will be ignored and the keypad resets once again.
Special Characters:

To blank the output signal altogether, enter zero for input.
i.e.: 0e
¾
To apply compensation to any input press: +
This clears up the display when long cables are used. The LED on the front panel will be brightened.

To turn compensation off for a particular input press: -
This causes the signal gain to go down, and the LED on the front panel will be dimmed.
*** The compensation setting for each channel is stored in non-volatile memory ***
