9.  Perimeter Switch and Perimeter Wire 
The Robomower  cannot  operate  without a  perimeter wire  installed  and  activated  through  the 
Perimeter Switch.  In the event the Perimeter Switch is turned off or otherwise fails to function, the 
Robomower  will  stop  operating.   Likewise,  should  a  break  in  the perimeter  wire  occur  the 
Robomower  would  again  stop  operation.    A  break  in  the  perimeter  wire  prior  to  operation  will 
prevent the Robomower from operating.  The  Robomower  can only operate within the boundary 
of the perimeter wire. 
10.   Auto-Off Perimeter Switch 
The auto-off feature  of  the  perimeter  switch  shuts  down the  perimeter  switch  operation  after 
approximately 5 hours  of  continuous  operation.    This  is typically  1 to  2  hours  after which a fully 
charged Power Pack will need to be re-charged. This helps to prevent unauthorized persons from 
attempting to re-start the Robomower after it has completed its’ operation. 
11.   Over-Current Monitoring Protection 
Each  of  the  three  blade  motors  and  each  of  the  two  wheel  drive  motors  are  monitored 
continuously during operation for any situation that may cause these motors to over-heat.  In the 
event this is detected, the Robomower will stop operation of at least that motor and possibly the 
mower itself  and  indicate  that  the  motor  is  cooling down. While  unusual, this may happen  when 
the mower is put in grass that is severely overgrown; the underside of the mower is clogged from 
poor cleaning maintenance; the mower has encountered an obstacle that is unable to activate the 
bumper sensor preventing it from moving; or a problem landscape area has caused the mower to 
get stuck and is preventing it from moving.
