1.10 TROUBLE SHOOTING
If you have followed these instructions correctly, it should function normally.
Some common symptoms are, the system doesn’t work, buzzer alarms, shutdown
after running a very short period,… etc. If so, please check the following steps to verify
and correct it.
1) Check all connection (if pinouts is correct, if any connection loosed, if the direction
is incorrect,… etc.).
2) Check if any short-circuit or defective peripherals by plugging out the power
connector from each peripheral, one at a time. Shall the system functions again, you
have solved the problem.
