Charger’s RFID card reader sometimes fails to detect cards unless they are swiped multiple times.

Safety first: RFID troubleshooting is low-voltage; opening the unit still requires power OFF.

• 1. Test multiple cards: Try several authorized cards or fobs. If only one is problematic, replace that card.
• 2. Remove obstructions: Ensure no metal plates, stickers, or covers are placed over the RFID reader area.
• 3. Internal antenna check (qualified): With power OFF, open the charger and verify that the RFID antenna is properly positioned behind the reader area and securely connected.
• 4. Replace RFID module: If detection remains weak across all cards, replace the RFID reader module or front panel assembly.

When to call a professional: For module replacement, contact a qualified technician.
