6.3.4 Check PCB of the Units
This function is used to Self check the PCB of the indoor and
outdoor units.
1 Select “Check PCB of the Units” on the “Check Menu”
screen and press “OK”.
2 Press “ ”, “ ”, “ ”, or “ ” to select the indoor unit. Press “OK”.
If there is only one indoor unit connected to the wired remote
controller, this screen is not displayed (the screen in Step3 is
shown).
3 Check result is shown.
