Using Alphanumeric Entry Mode
Alphabetic characters can be included in the SDM as follows:
1
Press the
Alphanumeric
key ( ) to enter alphanumeric entry mode.
While alphanumeric entry mode is active, the
ALPHANUMERIC
indicator is illuminated
and the alphabetic characters marked on the keypad are now available for inclusion in
the SDM.
2
Specify the required alphabetic character by using the alphanumeric keys, as follows:
◆
Pressing a key with three or more alphabetic characters toggles it between the
values shown on the keypad and a blank space. For example, a single press of the
key selects 3, two presses selects D, three presses selects E and four
presses selects F. A further press of the key selects a blank space.
◆
The key toggles between a 0 and a blank space.
◆
The key toggles between a 1, a dash and a blank space.

Once the required character is displayed, select by pressing the
Enter
key ( ).
The selected character is then moved one place to the left, and the flashing cursor
remains at the point of entry, ready to accept the next character.
Alternatively, the displayed character can be selected by pressing a different
Alphanu-
meric
key. While this method is quicker that using the
Enter
key, it can be used only
when the next character does not require the use of the same key.
An alphabetic message can be edited in the same way as a numeric message.
