(An invalid setting value may have been selected for the indoor unit.) (6) Repeat steps to 5 to perform additional settings. Press the SET TEMP. buttons ( ) ( ) and FAN button simultaneously again for more than 5 seconds to cancel the function setting mode. In addition, the function setting mode will be automatically canceled after minute if no operation is performed. (7) After completing the Function Setting, be sure to turn off the power and turn it on again.! CAUTION After turning off the power, wait 3 seconds or more before turning on it again. The Function Setting will not become active unless the power is turned off then on again.
