SPECIAL CALLS
Short Data Messages (SDM)
Short data messages may be set up, sent and
received using the radio keypad and controls.
Outgoing data messages from the keypad are
limited to alphanumeric data in any
combination of up to 20 characters (which
include address information and data selection
characters).
Receiving Short Data Messages
On receiving a Short Data Message:
The data message icon
K
is lit whenever
SDMs are in the data message calls list, i.e.
displayable, unless the message display has
been turned off (refer to Displaying Incoming
Data). Note that the data message icon
flashes when data messages in the calls list
are unread. The icon is lit permanently when a
message is read and retained in the calls list.
Displaying Incoming Data
The short data message display can be
switched ON and OFF using the pre-
programmed Data Display button, or using the
keypad or via the menu. Refer to Settings -
Data Display for
details.
The SDM display defaults to ON, however the
option setting is retained when the radio is
switched off.
Note: This feature is important if the radio is being
used with external data terminal equipment
(DTE), to prevent loss of data messages.
With the SDM display set to ON, on reception
of a valid SDM, either it can be displayed by
the radio and/or passed to external DTE. In
either case, the SDM is received and accepted
(acknowledged) by the radio. Only if the SDM
is of an un-displayable format AND the
external DTE is disconnected, is the SDM
rejected by the radio.
With the SDM display set to OFF, on reception
of a valid SDM, it will not be added to the data
message calls list for display, but passed to the
external DTE, which if accepted will be
acknowledged by the radio.
