Section G. TROUBLESHOOTING
This section is intended for problem-solving that can be addressed on the field. If the
problem is not solved using this guide, do not open the equipment and try to repair it by
yourself. Please contact Canam Technology for service and repair.
G.1 DC POWER ALARM
1. Check that the external +15VDC power supply is connected to the correct AC
power outlet and it is turned on. Measure the Power Supply DC output using a
multimeter to ensure that the 15V are present.
2. If the power supply is connected but no 15V were present, change the power
supply to another power outlet. If this solves the problem, repair the power outlet.
3. If there are no 15V at the Power Supply output, replace the power supply.
4. If the 15V are present, check the cable that connects the power supply to the
M4-ChOLC. If it is damaged, replace the cable.
5. If cable replacement does not fix the problem, please contact Canam
Technology.
G.2 RF STATUS ALARM
1. Use the test circuit shown in Figure 14.
2. Adjust the RF Generator frequency to match the frequency of the M4-ChOLC
Module.
3. Adjust the RF Generator Power (P
gen
) to -50 dBm.
4. If there is no output signal present, verify that the RF Threshold level is properly
adjusted. See section
F.3 for details.
5. If after adjusting the RF Threshold there is no signal, use Canam’s C-PROG
software to set the M4-ChOLC Operating Frequency.
6. If no output signal is still present, contact Canam Technology for repair.
