LEDs signal, not allowing any other MBD-8G to switch to any antenna and rotator already in use. Any conflict is signaled on the front panel of the MBD-8G by blinking the push button LED for two seconds, and the rotator LED with short and continuous flashes every second. The rotator signal remains as long as there is a conflict.

Immediately after programming the Split mode, perform the function test by pressing and releasing the PTT of the radio and observing the push buttons of the MBD-8G that should alternate between the chosen antennas. To exit Split mode simply change the radio band or press the transmit antenna push button.

24 from 225.0 MHz to 430.0 MHz, Band 25 from 430.0 MHz to 450.0 MHz, Band 26 Above 450 MHz 9- Antenna memory per band The MBD-8G has a memory for each of the eight antennas so that whenever an antenna is selected this memory registers the band selected by the Radio. With each band change in the radio the MBD-8G will activate the last antenna that was used in that band.
