0x04 Detected carrier frequency LSB LSB
0x05 Power threshold LSB LSB
5 Data Byte 3 Factory Use Only 0xAA
6 Not used
7 Checksum Algebraic Sum of bytes 1-6 Sum of bytes
1-6
*Notes:
Command 0x05
For CSM mode the setting must be at 20.1 dB below rated power. For burst
mode the setting must be between rated power and no lower than 20 dB below
rated power.
Command 0x03, Data Byte 2
The smallest delay is 0x01, which is 1ms. The delay value of 0x00 is equal to
0xFF and gives a 256ms delay. The delay value of 0xAA is the only exception; it
will not change anything. It is aimed to keep compatibility with previous versions
of the software. It should be noted, that the time delay may not be accurate when
the EEPROM write command is being executed (delay time longer by few ms).
