2. Setup and Programming
2.1 Battery Installation
The remote comes with a pre-installed 12V A23 battery. If replacement is needed:
- Carefully open the remote casing, typically by sliding the back cover or gently prying it open at a designated notch.
- Remove the old 12V A23 battery.
- Insert the new 12V A23 battery, ensuring the positive (+) and negative (-) terminals are correctly aligned.
- Close the remote casing securely.
2.2 Setting Dip Switches
The 390GED21V remote uses 12 dip switches to match the code of your existing Genie garage door opener or receiver. This ensures secure and unique operation.
- Locate the dip switches inside your existing working garage door remote or on the garage door opener unit itself. These are typically small switches labeled 1 through 12.
- Open the casing of your new Stinger 390GED21V remote to expose its 12 dip switches.
- Carefully match the position (ON/OFF or +/0/-) of each dip switch on your new remote to the corresponding switch on your existing remote or opener unit. Ensure an exact match for all 12 switches.
- Once all switches are set, close the remote casing.
2.3 Testing the Remote
After setting the dip switches, test the remote's functionality:
- Stand within a reasonable range of your garage door opener.
- Press the button on the Stinger 390GED21V remote.
- Observe if the garage door responds (opens or closes). The remote's test/operate LED light should illuminate when the button is pressed.
- If the door does not respond, re-check the dip switch settings and battery installation.
3. Operating Instructions
To operate your garage door using the Stinger 390GED21V remote:
- Ensure you are within range of your garage door opener.
- Press and release the single button on the remote.
- The garage door will either open or close, depending on its current state.
- The remote's LED light will illuminate briefly when the button is pressed, indicating that a signal is being transmitted.
4. Maintenance
