N.B.
In case there are two caller units (frontgate and backgate), only the unit whose call button
1 is first pressed will send out a call signal to handset, the remaining unit will keep in
standby mode until the conversation is over. If its call button 1 is pressed during this
period, two “Be-Be” sound will be heard and the call indicator 4 flashes for two times, indicat-
ing the unit is under standby mode.
