3. Operating Instructions
Using the Wireless Remote Control:

Setting Upper and Lower Limits:
To ensure proper operation, you must set the upper and lower travel limits for your blind.

Consult the detailed programming guide provided with your remote control for exact steps.
Smart Home Integration:

- Obstructions: Check for any physical obstructions preventing the blind from reaching its full travel.
Unusual Noise During Operation:
