(2) Cautions
1) ME remote controller and MA remote controller cannot
both be connected to the same group of indoor units.
2) No more than 2 MA remote controllers can be connected
to a group of indoor units.
3) A transmission booster is required in a system to which
more than 32 indoor units (26 units if one or more indoor
units of the 200 model or above is connected) are con-
nected.
Refer to the DATABOOK for further information about
how many booster units are required for a given system.
