The power LED lights up. If no abnormality is stored in the
memory, three beeps sound will be heard.
5. Every press of the button (up or down) will increase
abnormality numbers and transmit abnormality code
signal to the main unit.
6. When the latest abnormality code on the main unit and
code transmitted from the remote controller are matched,
power LED will light up for 30 seconds and a beep sound
(continuously for 4 seconds) will be heard. If no codes are
matched, power LED will light up for 0.5 seconds and no
