right side of the field. If you make a mistake, you can press
CLEAR
to
clear the entire number and re-enter it, or you can press the left-arrow
cursor key to reenter particular digits, one at a time.
When the 941X is expecting letters to be entered, such as waypoint
names and descriptions, the operation is slightly different. Each key is
labeled with three letters (or other special characters) and a digit.
For example, the upper left key is labeled with the letters
A
,
B
,
C
and the
digit
1
. Pressing the key one time displays the letter
A
. Press the key
again to display the second letter,
B
. Pressing a third and fourth time
displays the letter
C
and the digit
1
, respectively. A fifth press brings you
back to the letter
A
again.
To enter a character, first find the key containing the character, and
press that key one to four times to display the desired character. Finally,
move the cursor to the next character position by pressing the right ar-
row symbol on the cursor key.
The keypad also contains
CLEAR
and
ENTER
keys for erasing or enter-
ing data that has been typed on the keypad. Pressing the
ENTER
key is
always the last step when entering or changing data, or acknowledging
an action. The
CLEAR
key removes any data you typed before you press
ENTER
, and sets the field to all blanks or restores it to its value before
you changed it.
Occasionally, the 941X needs to inform you of something or ask permis-
sion to do something. When this happens, a special information or ques-
tion window appears on the display. The window contains an
exclamation point (“
!
!!
!
”), an “
INFO
” label, or a large question mark (“
?
”),
and a message for you to read.
Alarm messages contain information you should read right away. Alarms
are communicated by the flashing exclamation symbol in the bottom-
right portion of the display.
