CTCSS/DCS Drop
When a call has come into the Model 748, and the caller has selected a user to call, the Model 748
generates CTCSS or DCS (depending on the CTCSS/DCS encode) and sends out the selective
calling, and then the ringing. If
CTCSS/DCS drop
is ON (yes), then the CTCSS or DCS encode will
be dropped when the radio user answers. If it is OFF (no), the encode will continue for the duration
of the call.
If the system has a fleet of radio users that are on the same tone, you will want the tone/code to drop
when the correct user answers, otherwise everyone else in the fleet will have to listen to the call. If
the system has a tone per user, leave the
CTCSS/DCS drop
OFF (no) so that the radio users will not
have to hear additional channel traffic.
How to program it:
Access the Model 748 through your direct connected PC or terminal, or remotely from your PC
connected to a modem via the Model 748's internal modem.
Once connected to the Model 748 and the Main Menu is on the screen, type “1” and press
ENTER
,
and the Interconnect Menu will appear. Type “3” and press
ENTER
, the User Menu will be
displayed using the currently selected user's data. Select the User number you wish to program (see
“User Range” later in this section). Select the item number for
CTCSS/DCS drop
and press
ENTER
.
The currently selected mode or state will be shown along with a message instructing you to press the
space bar to change the mode or state, and to press
ENTER
to accept the current mode or state. Each
time the space bar is pressed, the mode or state changes. Once the mode or state you desire is
displayed, press
ENTER
to accept it. Note that if you accidentally pass the mode or state you want,
keep pressing the space bar and the Model 748 will wrap around (when the last choice is displayed,
it will return to the first one).
The default setting for this command for all users is OFF.
CTCSS/DCS drop
is supported by block or range programming. See “User Range” later in this
section for details.
