It is not recommended to keep the belt pack (ITC-100SL)
constantly in talk mode, but only activate talk when needed. This is also recommended for less confusion
between other members of the crew.
Communications between the host and the belt pack are not full duplex. Which means that
if all lines are open, and talk is activated, the communication with the largest volume will be heard, and
will cancel out the rest. We also recommend the host member wait 1-2 seconds after pushing the
1-8 buttons on the host so that the ring passes on the belt packs.
