ADJUSTMENT GUIDE 
- FORCE SETTINGS 
FOR HELP-1-800-35-GENIE OR WWW.GENIECOMPANY.COM
Force settings are pre-programmed at the factory 
and "learned" during the Open/Close Limit settings 
steps.  Some additional Force may be increased.  
For normal use, Force settings should not need 
adjustment with this unit.
However, conditions that might suggest an 
adjustment is necessary are;
Doors with very stiff weather seals.
Doors that start down, then STOP and reverse 
before they close.
Doors that start up, but STOP before they 
completely open.
