Failure modes stored in the nonvolatile memory of the indoor unit are redisplayed by remote control.
This is effective in checking the failure mode after you turned off or restarted the product without checking the frequency of
lamp blinking on the self-diagnosis display. (It stores the last 5 failure modes.)
This function also stores less frequent failure modes that do not lead to the indoor unit giving a self-diagnosis display.
By clearing the memory and double-checking the contents of the memory later on, you can catch failure phenomena that
cannot be detected at the time of a visit.

< Cautions >
・
This function is effective only once immediately after the power is turned on. It will not work if you have performed another
remote control operation beforehand.
Note also that it may not function in response to a procedure other than the above.
(If it does not work, turn off the power, turn it back on, and repeat the procedure.)
・
If the memory stores nothing, performing a redisplay operation will not blink the lamp.
・
For a normal operation, turn off the power and turn it back on. After the above operation, the product will not receive a
remote control signal normally.
・
After clearing the troubleshooting data, turn off the power. (If you do not turn off the power, the product will become
unresponsive to remote control signals.)
