The MDT-500-2 mobile radio supports the connection of up to two consoles,
either a Colour Console or a Handset-based Console (via an Interface and
Handsfree box), or an Applications Interface Unit, which is similar to a
console but does not have a keypad and display. Through the use of a
console, the MDT-500-2 mobile radio can support the connection of up to 6 of
the following audio accessories:
The MDT-500-2 mobile radio supports Colour Console connection (SCC3).
SCC3 allows you to connect two of the following audio accessories at the
same time:
a hands-free kit
a fist microphone
a handset audio accessory
built-in handset
up to one hands-free kit
If two users are using the same mobile radio, operational procedures are
required to ensure that the actions of the two users do not conflict.
On some configurations it is possible to have a hands-free kit attached to each
console. If this is the case, only one of the remote microphones is live during
a call. The remote microphone which is live is the one attached to the console
which accepted or made the call or switched the call to hands-free.
