Fujitsu UTB-GCA Operating Manual page 26

Notes When several of central remote controllers have been connected in one system, the centrally controlling
items, can be set or removed by using any central remote controller in the system. If the set centrally
controlling items are not hoped to be removed by setting other central remote controllers, please set the
DIP-SW 2-5 "enable / disable setting of the standard remote controller prohibition function" to disable
position. (It is recommended that only the host central remote controller should be set to enable and the
others should be set to disable.)
