Selecting TMO or DMO Operation

General

In Trunked Mode Operation (TMO) the CM5000 is used with
the infrastructure services within system coverage.
In Direct Mode Operation (DMO) the CM5000 is used without
infrastructure services required.
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.
A CM5000 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
CM5000 (see CommType"Gateway/Repeater Selection" on
page 28).
In DMO it is only possible to place Group Calls, Emergency
Group Calls and Private Simplex Calls.
