Setting Travel Limits : Via Transmitter
The GDO-9 has the alternate ability to set travel limits 
using the transmitter, allowing free movement around 
the garage to better assess the desired limit positions.
Step 14.1 - Code a Transmitter for Limit Setting
Ensure the opener is powered up.
Press and hold the DOOR CODE button (Fig. 25).
Press Button 1 on the transmitter for two seconds 
(Fig. 26). Release and pause for two seconds. 
Press the Button 1 again for two seconds.
Release the DOOR CODE button.
Step 14.2 - Setting Limits via Transmitter
Engage the C-Rail’s trolley (attached to the door via 
the arms) with the chain or belt index by moving the 
door. 
If the trolley does not “click” fi rmly onto the chain 
index, pull the cord backwards until it locks in place, 
and try again.
Press and hold Button 4 on the transmitter to close 
the door. When the door is approx. 20mm from the 
ground, release Button 4 (Fig. 26).
Each press of Button 4 will allow you to “inch” the 
door closed. Keep doing this until the door reaches 
the desired close limit position.
If the door closes too far, press Button 1 to “inch” 
the door towards open
When happy with the close limit position, press 
Button 2 to store this in memory.
Press and hold Button 1 to open the door. When 
approx. 20mm from the desired open position, 
release Button 1.
Each press of Button 1 will allow you to “inch” the 
door open. Keep doing this until the door reaches 
the desired open limit position.
If the door is opened too far, press Button 4 to “inch” 
the door towards closed.
IMPORTANT WARNING: The door will 
automatically close, open and close again once 
Step 14.2(j) is performed. Ensure that no persons 
or objects are in the door’s path.
When happy with the open limit position, press 
Button 2 on the transmitter to store into memory.
The door will now automatically close, open and close 
to calculate the safety obstruction settings. After 
this, the opener can be operated with the OPERATE 
button.
Step 14.3 - Resetting the Door Limit Positions
Limit positions can be deleted by the following steps:
Follow Steps 13.2, as outlined previously.
Repeat Steps 14.1 and 14.2 to set new travel limit 
positions.
There is no need to re-code the transmitter (Step 
14.1) upon resetting travel limits. The transmitter 
will still be stored in memory.
