6. Setup and Programming Instructions
To program your ASONPAO Linear DTC Delta 3 remote, you need to match its internal dip switches to the settings of your existing Linear Delta 3 receiver or an existing working remote. This process involves opening both devices and setting the switches to an identical pattern.
- Access Dip Switches:
a. For the ASONPAO remote: Use a small Phillips screwdriver to remove the screw on the back of the remote (under the visor clip). Carefully open the casing to reveal the internal circuit board with the 8 dip switches.
b. For your existing Linear Delta 3 receiver or remote: Locate its dip switches. Refer to its specific manual if you are unsure how to access them. - Match Dip Switch Settings:
Observe the ON/OFF positions of the 8 dip switches on your existing Linear Delta 3 device. Using a small tool (like a pen tip or a small screwdriver), carefully adjust the 8 dip switches on your new ASONPAO remote to exactly match the pattern of your existing device. Ensure each switch is firmly set to either the ON or OFF position. - Reassemble and Test:
Once the dip switches are matched, carefully close the casing of your ASONPAO remote and secure it with the screw. Test the remote by pressing the button while within range of your garage door opener. The garage door should respond.
