WhenswitchingtheDIPswitch(SW1)ontheindoorunitPCboard,be
suretoturnoffthepowersupplytotheindoorunit.Otherwise,thePC
boardoftheindoorunitmaybedamaged.
Thereare2methodstoconnecttheremotecontrollercabletotheindoor
unit.Oneistheconnectionusingconnectingcable(Includedintheindoor
unit),andtheotheristheconnectiontheremotecontrollercableiscon-
nectedtotheexclusiveterminalblockoftheindoorunit.
(Forthedetails,refertotheinstallationmanualoftheindoorunittobe
used.)
5.4.1. Whenconnectingtotheconnector
(1) Useatooltocutofftheterminalontheendoftheremotecontroller
