Troubleshooting
If the receiver and transmitter cannot operate normally, try the following steps:
- No response from receiver: Check power supply (AC 85V-250V). Ensure transmitter batteries (2x CR2016) are not depleted. Verify pairing (re-pair if needed). Check for obstructions or excessive distance (up to 50m open space).
- Intermittent operation: Weak transmitter battery (replace). Interference from other RF devices. Extend receiver antenna for better signal.
- Incorrect operating mode: Reprogram the desired mode (see Operating Mode).
- Device not activating under high load: Ensure load does not exceed 30A (7200W). Check relay condition (designed for over 100,000 operations).
Maintenance
- Cleaning: Wipe with a soft, dry cloth. Do not use liquid cleaners.
- Battery replacement: Replace transmitter batteries (2x CR2016) when range decreases or LED dims. Ensure correct polarity.
- Waterproofing: IP65 design resists rain and sand, but avoid submersion. Check seals periodically.
- Storage: Store in a cool, dry place when not in use.
