Master, you may use the PT to activate talk for the two-way radio.

OPERATING MULTIPLE DR10-900 SYSTEMS IN ONE
LOCATION
Each separate DR10-900 system should use the same Group and
Security Code for all devices in that system. CrewPlex recommends that
systems operating in proximity to one another set their Groups to be at
least ten (10) values apart. For example, if one system is using Group 03,
another system nearby should use Group 13.
