Start-Up Shortcuts
Several shortcuts are available to power up the VM700A and put it immediately
into a specific mode. Each of these shortcuts involves powering up the VM700A
while pressing certain combinations of front-panel keys. To use a shortcut, power
down the instrument, press and hold the indicated key(s) on the VM700A, and
power up. Hold the keys for approximately 3 seconds after powering up to select
the desired mode. Table 9-5 summarizes shortcuts and the keys that enable them.
