TMO Mapping
Mapping between DMO and TMO talkgroups. The mapped TMO talkgroup is selectable and derived
from the Talkgroup list.
It's possible to associate a DMO talkgroup configuration to a TMO talkgroup configuration. This
means that if you are on TMO talkgroup 3, for example, then you are not bound to use DMO
talkgroup 3 should the user switch to DMO. In your DMO fleetmap, it's possible to associate any
TMO talkgroup to ANY DMO talkgroup, so in this example you could make DMO talkgroup number
23 the relevant DMO talkgroup for TMO talkgroup number 3.
When copying DMO or TMO talkgroup list to another new codeplug, mapping will be lost. Use
cloning to keep values.
You cannot map a DMO talkgroup to an unprogrammed TMO talkgroup.
To select the correspondent TMO talkgroup, put the pointer into the field value, click on the arrow,
and drag the pointer to the desired talk group.

Key Group
This is an additional parameter to DMO talkgroups. It specifies the key group associated with the

For each DMO group, when key grouping method is <K, E>, the available values that can be
selected are one of KGj (j=1...K) or NO_KG.
