 Recommendations

1. In order to achieve the optimum reception and also extend 
    the operating distance, please leave an “open space” 
    between the receiver and transmitter.
2. Keep the devices away from the metal objects or any 
    interference sources, at least 50 cm.
3. Remove batteries from the battery compartment when the 
    receiver will not be used for long time.
4. When you need to replace the batteries, please replace both 
    batteries at the same time with new ones.
