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 “
How to reprogram the preset frequencies of the CDP-TX-07MP/CDP-
RX-07MP”
