In many cases, it is sufficient to select “reset alarm” in order
for the product to revert to normal operation. If a green light comes on
after selecting “reset alarm”, the alarm has been remedied. If a red light
is still visible and a menu called “alarm” is visible in the display, the
problem causing the alarm still remains. If the alarm initially disappears
and then returns, you should contact your installer.
