CCTM Error Codes Once the radio is in CCTM, the CCTM commands may be entered as
shown in Table 4.3 to Table 4.7. Depending on the command, a response
might or might not be displayed. If an error occurs, an error code will be
displayed. Possible error codes are listed in Table 4.10.
Table 4.10 CCTM error codes
Error code Description
C01 An invalid CCTM command has been received. Enter a valid CCTM command.
C02 A valid CCTM command with invalid parameters has been received. Re-enter the CCTM
command with valid parameters.
C03 A valid CCTM command has been received but cannot be processed at this time. Enter the
CCTM command again. If the error persists, power the radio down and up again, and re-enter
the CCTM command.
C04 An error occurred on entry into CCTM. Power the radio down and up again, and place the
radio in CCTM again.
C05 The radio has not responded within the specified time. Re-enter the CCTM command.
X04 The DSP is not responding. Check the DSP pin connections. If the error persists, replace the
DSP.
X05 The version of the DSP is incompatible with the version of the radio firmware. Replace the DSP
with a later version.
X06 The internal configuration of the MCU is incorrect. Adjust the configuration.
X31 There is an error in the checksum for the model configuration.
X32 There is an error in the checksum for the radio’s database.
X35 The radio temperature is above the T1 threshold and a reduction in the transmit power is
impending. To avoid damaging the radio, stop transmitting until the radio has cooled down
sufficiently.
X36 The radio temperature is above the T2 threshold and the inhibiting of transmissions is
imminent.
X37 The supply voltage is less than the V1 threshold.
X38 The supply voltage is less than the V2 threshold and the radio has powered itself down.
The radio will not respond to the reset command character ^ .
