Operating Instructions and Installation

4-3-25 When the remote control is not receiving

1. Check if the connector was normally assembled.
2. Put the set in operation and check the voltage of No. 3 and No. 1 of the main PCB CN45 while operating the remote control. When
the voltage descends below 3V, the assembly module PCB is normal and the main PCB is poor. Then replace the main PCB.
3. Replace the assembly module PCB because the module PCB is poor if the voltage between No. 3 and No. 1 of CN45
maintains 5V after the remote control starts operation.
