TK SR-2 Fault

Hi guys,
I am new to this site. I have 2 faults codes on sr-2 alarm window: 4 and 204. I found a plastic back stuck in evaporator so it was preventing airflow. I fixed but need to reset these codes. Can anyone pls help.
Thanks

Verify if discharge air sensor is faulty (check connector for this sensor as they tend to ingress water). Codes will have to be cleared from Guarded Access.

switch unit on and press 'menu' to bring up 'alarms';

while in alarms press and hold first and third buttons (counting from your left side).You are now in Maintainence Menu.

Press 'next' till you get to time and date.

Now press and hold first and fourth buttons.

Now in guarded access

:D
Thanks Mate
