Specifications - RCF BM 3003 User Manual

All BM 3003 paging microphones that are connected to the same line use a
common ES 3323 amplifier input, therefore only one paging microphone at a
time can be activated.
If a paging microphone has already been activated, all the others are auto-
matically disabled (their TALK button 5 does not work); this state is indicated
by the respective LED:
ON / BUSY LED 1 flashing red
The selected ZONE LEDs 2 indicate green.
