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.

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).

Entering TMO or DMO

Enter TMO or DMO in one of the following ways:

• From the Home display press Optns

and select Direct

Mode

if the CM5000 is in TMO.

• From the Home display press Optns and select Trunked

Mode

if the CM5000 is in DMO.

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.
