● Panel combination check
In order to avoid improper combination of the unit and
panel, the following messages are shown in the STAND-
BY source during the Test mode. The message is de-
cided based on the combination of System μ-com and
panel.
<Mother for K destination + Panel for K destination >
<Mother for E destination + Panel for E destination>
<Mother for M destination + Panel for M destination>
< Mother for K destination + Panel for E destination>

[Note]
1. The above indication of the "NG" message is based
on the decision made by the panel μ-com. In the panel
μ-com of the model that is already T/O and does not
have the integrated BT, the combination with the mother
of the model that has the integrated BT is not consid-
ered. Thus the indication of OK or NG is not correct for
the combination of <Mother of the model with the inte-
grated BT and Panel of the model without the integrated
BT>.
2. In the combination of the above 1 and any case of the
above NG, the power is forcedly turned off if the unit is
normally started up (not in the Test mode startup).
