ERROR MESSAGES
The DMP248 transmitters go through a self-diagnostics procedure
when the power is switched on. When the procedure does not reveal
any errors or faults, the transmitter starts operating normally. If errors
or faults are found, the transmitter outputs an error message. The error
messages can be divided into two groups: error messages after the
reset and error messages during operation.
