Air Interface Data Rates and Error Correction

The SX5e supports both transparent (no error correction) and non-transparent (error correction)

data connectivity along with different air interface data rates. Check with your carrier to deter-

mine which is right for your application. If you are not sure what your carrier supports, use the

default setting of non-transparent
