LX2400S Configuration Parameters and Commands

3.2.6.1 Configuration Parameters

The Host can program various parameters. The data is stored in EEPROM and becomes active on the next
power on reset of the LX2400S. Table 2 gives the locations and functions of the parameters that can be read
or written by the Host. Factory default values are also shown.

Note: Non-Host parameters are used in the EEPROM. The Host must only write to the locations in Table
2. Any other location may cause the radio to malfunction.
