When a garage door is fully closed, there shouldn’t be 
any space between the door and the garage floor. When a 
door is fully open, it should provide enough clearance for 
vehicles to travel safely underneath it. Use caution when 
setting the open position for single-panel garage doors. If 
a single-panel door is opened so far that it begins to slant 
backwards, excessive bouncing and jerking may occur as 
the door moves, see figure 71.
NOTICE:
Do not open or close the garage door using the indoor 
keypad or remotes until the travel limits have been 
properly set. Doing so could cause severe damage to 
the garage door or the garage door opener.
Connect the garage door opener to an AC power supply. 
 NOTE: Make sure the power supply is normal household 
voltage, 120 volts, AC only, 60 Hz
Before setting the travel limit:
Pull the emergency release rope down and manually open 
the garage door until the outer trolley engages the inner 
trolley.
WARNING:
Confirm that the inner trolley is in the orientation shown 
in Figure 72. An incorrectly installed Inner Trolley could 
result in the garage door opener operating in the opposite 
direction from its intended movement and result in death 
or serious personal injury from the moving garage door.
Once you begin setting the travel limits, you have two min-
utes to complete each step. If a step is not completed within 
two minutes, travel limit information for the open and closed 
position will be erased.
To set the travel limit for the open position:
Open the console door.
Press and hold the UP button for three seconds. After 
you release the button, it will begin blinking and continue 
blinking until the travel limit has been set.
Press and hold the UP button to move the garage door 
to the open position.
For fine adjustments, press and release the UP or DOWN 
buttons.
Once the door is in the open position, press the SET 
button to store the travel limit. Once the travel limit 
is stored, the UP button will stop blinking and shine 
continuously.
NOTE: If the safety sensors are obstructed during this 
process, travel limit information for the open and closed 
position will be erased.
