If enabled, high speed operation can be locked out
if required in noise sensitive areas.

speed operation if the set time is exceeded and
conditions allow.
The High Speed Lockout key is a toggle. If high
speed is enabled, then pressing the key will
disable high speed operation. Pressing the key
again will enable high speed operation.
