2. Initial Programming
The MX-350 can be programmed using pre-programmed codes or by learning commands directly from your original device remotes.
- Code-Based Programming: Refer to the separate code list provided with your remote or available from the manufacturer's website. Select the device type (e.g., TV, DVD) and enter the corresponding code.
- Learning Function: This allows the MX-350 to 'learn' commands from your existing remote controls. Position the MX-350 and your original remote face-to-face, typically 1-3 inches apart. Follow the on-screen prompts on the MX-350's LCD to enter learning mode and transfer commands.
For detailed programming steps, consult the full programming guide or contact customer support.
