Use the UP/DOWN arrow keys to make your selection. The Data
Operated Squelch (DOS) criteria allows the user to select whether the
DOS detect algorithm considers 1200 Hz or 1800 Hz alone to be a valid
data detect, or whether both 1200 Hz and 1800 Hz are required.
Note: Setting the DOS Criteria to 1200 Hz and 1800 Hz tends to
minimize falsing on voice or noise.
The default is 1200_and_1800.
Enter a value directly or use the UP/DOWN arrow keys to make your
selection. When a data signal is detected and then lost, the radio will
not immediately unmute for voice. A time delay specified in this field
will be executed first. During this delay period, if the data signal is
detected again, the radio will remain muted and this timer will stop
and be reset. The range of valid values is 0 (zero) to 500 ms, in five-ms
increments. When this field is set to 0 (zero) , DOS is disabled.
Note: This timer helps prevent temporary loss of DOS Mute in
areas of poor signal strength or high multi-path distortion.
The default is 100 ms.
Enter a value directly or use the UP/DOWN arrow keys to make your
selection. This field consists of the Group ID and the Individual ID.
The Group ID ranges from 0 (zero) to 15, and the Individual ID ranges
from 1 to 99. These IDs are used when a subscriber unit initiates Group
or Individual calls.
The default is 0 (zero) for Group ID, and 1 for Individual ID.
Enter a value directly or use the UP/DOWN arrow keys to make your
selection. This field consists of the Group ID and the Individual ID.
The Group ID ranges from 0 (zero) to 15, and the Individual ID ranges
from 0 (zero) to 99. These IDs are used to determine whether there is
an ID match when a subscriber unit decodes ATIS Group or Individual
calls.
The default is 0 (zero) for Group ID, 0 for Individual ID.
Enter a value directly or use the UP/DOWN arrow keys to make your
selection. This field is used to distinguish groups of users. If two radios
are programmed with the same channel frequency, ATIS Initiator ID
(Group and Individual), and PL tone, but are used by two different
people, the ATIS User Code is used to differentiate the two radios. The
user code can range from 0 (zero) to 3.
The default is 0 (zero).
This field is reserved for future use.
