MSAT Network to each radio. The radio displays the DN of the
current speaker during each call as a means of notifying other
subscribers who is talking.
Monitor Code – A code stored within each radio that controls when the
radio should join a Talk Group conversation.
Priority-1 Interruption – Network feature which allows a radio user to
interrupt a current speaker by pressing a specific key on the handset.
Private Mode – Private Mode allows two MSAT users to establish a private
Dispatch radio conversation over the Network. Users must be
members of a Private Mode Talk Group before Private Mode
conversations between them can take place.
PTT – MSAT Dispatch Radio users who wish to communicate with other
MSAT users within a Talk Group must press and hold a specific key on
the handset. This key is referred to as the Push-to-Talk (PTT) key.

which the radio belongs. A radio can have up to a maximum of 15 Tag
Numbers (and tag number 00 for private mode operation).

that can talk together in a Dispatch Radio conversation. Each radio can
be a member of up to 15 Talk Groups, but can participate in only one

2-digit Tag Number.
