5. Operating Instructions
The AS-RFD3520 kit includes two 5-button remotes for controlling your vehicle's functions. The ASDS-3520 is a 2-way LED remote, providing visual feedback, while the ASDS-1554 is a 1-way remote.
Remote Button Functions (Typical):
- Lock Button: Press to lock vehicle doors. On the 2-way remote, LEDs may flash to confirm.
- Unlock Button: Press to unlock vehicle doors. On the 2-way remote, LEDs may flash to confirm.

2-Way Remote Feedback:
The ASDS-3520 2-way remote provides visual LED feedback to confirm that commands have been received and executed by the vehicle. For example, after sending a remote start command, the remote's LEDs will indicate if the vehicle successfully started or if there was an issue.
6. Maintenance
Remote Battery Replacement:
The remote controls are powered by small batteries (e.g., CR2032 coin cell). When the remote's range decreases significantly or the LED indicators on the 2-way remote become dim, it may be time to replace the battery.
- Carefully open the remote casing using a small flat-head screwdriver or a coin.
- Note the orientation of the existing battery.
- Remove the old battery and insert a new one of the same type, ensuring correct polarity.
- Snap the remote casing back together securely.
General Care:
- Keep remotes dry and away from extreme temperatures.
- Avoid dropping remotes or subjecting them to strong impacts.
- Clean remotes with a soft, dry cloth only.
7. Troubleshooting
If you experience issues with your AS-RFD3520 Autostart Kit, consider the following troubleshooting steps:
Remote Not Responding:
- Check Battery: Replace the remote's battery as described in the Maintenance section.
- Out of Range: Ensure you are within the specified operating range of 5,200 feet. Obstacles like buildings or hills can reduce range.
- Interference: Strong radio frequency interference from other devices or locations can affect performance. Try moving to a different location.
Vehicle Not Starting Remotely:
- Vehicle Status: Ensure the vehicle is in park, doors are closed, and the hood is shut. Some systems require specific conditions for remote start.
- System Arming: Confirm the vehicle's security system is armed before attempting remote start.
- Fuel Level: Some vehicles will not remote start if the fuel level is too low.
Persistent Issues:
If troubleshooting steps do not resolve the issue, it is recommended to contact the professional installer who performed the initial installation or a certified Directed dealer for further assistance. Do not attempt to repair or modify the system yourself, as this may void the warranty and could cause damage to your vehicle.
