Setup
1. Battery Installation
The RETROSUN V11 remote control requires three (3) AAA alkaline batteries (not included). Follow these steps to install them:

2. Learning Function (Pairing)
The V11 remote control features a learning function to replicate commands from another infrared remote. This allows you to consolidate control for certain functions. Follow these steps:
- Press and hold the “Set” key on the V11 remote for 3 seconds until the indicator light remains steadily on.
- Press the specific key on the V11 remote that you wish to program (e.g., Power button). The indicator light will begin to blink.
- Point the infrared emission window of your original remote control directly at the infrared emission window of the V11 remote control (typically at the top).
- Press the corresponding key on your original remote control that you want the V11 remote to learn. The indicator light on the V11 remote will stop blinking once the learning is successful.
- Repeat steps 2-4 for any other keys you wish to program.
- After learning all desired keys, press the “Set” key again to exit the learning mode.

Maintenance
To ensure the longevity and optimal performance of your RETROSUN V11 remote control, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to clean the remote control. Avoid using liquid cleaners, solvents, or abrasive materials, as these can damage the surface or internal components.
- Battery Replacement: Replace all three AAA batteries when the remote's performance degrades or the indicator light does not respond as expected. Always use new alkaline batteries.
- Storage: Store the remote control in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
- Avoid Impact: Do not drop the remote control or subject it to strong impacts, which can damage its internal circuitry.
Troubleshooting
If you encounter issues with your RETROSUN V11 remote control, refer to the following common problems and solutions:
- Remote is not responding:
- Check if the batteries are correctly installed with the correct polarity.
- Replace the batteries with new AAA alkaline batteries.
- Ensure there are no obstructions between the remote control and the Zidoo media box's infrared receiver.
- Make sure you are within the effective operating range (up to 8 meters / 26 feet).
- Learning function is not working:
- Ensure the original remote control has working batteries and is transmitting a strong signal.
- Verify that the infrared emission windows of both remotes are pointed directly at each other and are in close proximity during the learning process.
- Repeat the learning steps carefully, ensuring the indicator light on the V11 remote blinks and then stops as described.
- Some original remotes may use different infrared frequencies or protocols that are not compatible with the learning function.
