CDP-RX-07MP reprogrammable frequency channels 

Each of the 4 preset channels are reprogrammable using values chosen from a frequency table containing 67 
values that consists of 433.920 MHz and values from 433.075 MHz to 434.700 MHz with 25 kHz spacing.  
To reprogram the preset channels, a dedicated setting program is provided. 
For details, refer to the application note “
