Selecting TMO or DMO Operation

General

In Trunked Mode Operation (TMO) the MTH800 is used with
the infrastructure services within system coverage.
In Direct Mode Operation (DMO) the MTH800 is used without
infrastructure services required.
While operating in DMO the propagation travels directly from the transmit-
ting 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 sta-
tion 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.
