Setup and Installation
Battery Installation
The keypad requires one 9V alkaline battery (not included). To install:

- Connect the 9V battery to the battery clip.
- Place the battery securely within the compartment.
- Close the keypad casing, ensuring it is sealed properly for weather resistance.
Mounting
The keypad is designed for screw-in installation and mounts with two screws.

- Mark the positions for the two mounting screws.
- Drill pilot holes if necessary.
- Secure the keypad to the surface using appropriate screws.
Programming the Keypad
This keypad uses 10 dip switches for programming. The code is entered directly through the keypad, eliminating the need to manually adjust physical dip switches on the unit itself.
- Locate the dip switch settings on your Multi-Code Receiver or existing remote. This will be a sequence of 10 switches, each set to ON, OFF, or MIDDLE (if applicable).
- On the 420001 keypad, enter the 10-digit code corresponding to your receiver's dip switch settings. Refer to the keypad's internal instructions for specific key presses to represent ON, OFF, or MIDDLE positions.
- Press the "ACCESS" button to save the code.
- Test the keypad to ensure it operates your garage door or gate opener.
Note: Programming typically takes less than 2 minutes. Ensure the keypad is within operational range of the receiver during testing.
Operating Instructions
To operate your garage door or gate using the Linear Multi-Code Keypad Transmitter:
- Enter your programmed 10-digit access code using the alphanumeric buttons.
- Press the "ACCESS" button.
- The LED indicator will illuminate, and your Multi-Code Receiver should activate, opening or closing your garage door or gate.
If the door or gate does not respond, verify your code and ensure the keypad is within effective range of the receiver.
Maintenance
- Battery Replacement: When the keypad's performance degrades or the LED indicator fails to light, replace the 9V battery. Follow the battery installation steps.
- Cleaning: Clean the keypad's exterior with a soft, damp cloth. Avoid abrasive cleaners or solvents.
