Compact Manual Virtual Wall
A Manual Virtual Wall must be turned on
by hand at the beginning of the cleaning
cycle to activate the barrier. A Manual
Virtual Wall and its power light will shut
off after 135 minutes. When battery
levels are low, the Virtual Wall power light will
blink slowly to indicate that it needs new batteries.
Compact Auto Virtual Wall
When an Auto Virtual Wall is set to “Auto”
mode, the power light blinks repeatedly
to indicate it is on. When battery levels
are low, the Virtual Wall blinks repeatedly
twice to indicate that it needs new batteries.
To save battery power, switch the Auto
Virtual Wall to “Off.” When in “Auto” mode, the
batteries should last approximately six months.
