Selecting TMO or DMO Operation
General
In Trunked Mode Operation (TMO) the MTP850 Ex/MTP810
Ex is used with the infrastructure services within system
coverage.
In Direct Mode Operation (DMO) the MTP850 Ex/MTP810 Ex
is used without infrastructure services required.
A MTP850 Ex/MTP810 Ex in DMO can communicate with the
trunked system (and vice-versa) through a gateway device.
To use that feature, please enable the gateway option in your
MTP850 Ex/MTP810 Ex (see “Gateway/Repeater Selection”
on page 52).

While operating in DMO the propagation travels directly from the
transmitting terminal antenna to the receiving terminal antenna,
with no assistance from any base station or tower. Therefore,
the range is critically dependent on the position of the user and
the antenna. To achieve best results, hold the terminal in the
hand as high as comfortably possible, and be sure not to
obstruct the antenna in any way. Be sure that the antenna is
clear from the body, cables, or other obstructions.
As there is no tower-mounted base station to assist, and the two
users are usually standing at ground level, the range is usually
shorter than that can be achieved towards a tower or hilltop. Any
obstructions (hills, buildings, etc.) between the users will further
decrease the range. Conversely, raising the terminal higher or
moving to a higher location may improve the range.
In DMO it is only possible to place Group Calls, Emergency
Group Calls and Private simplex Calls.
