The up and down arrow keys will scroll through the message list one at a time. The left and
right arrow keys will move through the list ten at a time.
4.1.3 Editable Field Messages (EFM)
A Quick Message can also be configured to have preset editable fields.
In order to use this type of messages, the CDU-250 must be pre-programmed using the
SkyWeb Hardware Management Console (HMC) or the SkyNet Serial Tool (please contact
SkyTrac Systems for details).
Once a Quick Message has been set with editable fields, the message will say “EFM”
across the top line of the selected message. Press enter to select the message and choose
the recipient.
The cursor will automatically bump to the field that is to be edited. A list of possible options
will have been set in the original programming. Use the up and down arrow keys to scroll
through the list of preset options, or use the keypad to enter in the information manually.
Once the field has been populated, the cursor will automatically jump to the next editable
field (if there is one).
Once all of the fields have the requested information, press the enter button to send the
message.
4.2 Phone
The Phone menu allows the user to make calls. There are three options under the Phone
menu item:
• Addr Book Dial – dial a number that has been saved in the address book
• Redial – dials the previously called number
• Manual Dial – manually dial a phone number
Regardless of the type of dialling that is being done, an international number must be
entered. To place a call, dial an international number: International Direct Dialling (IDD)
prefix of the country being called from (00 for Iridium) then the destination country code (1
for Canada and the US), followed by the area code and local number.
For example, to call SkyTrac Systems office, dial: 00 1 250 765 2393
Once a call has been initiated, the Activity indicator will stay on solid indicating the ISAT is
initiating the call. The Display also indicates the status of the call. It may take a moment for
the ISAT to initiate the call if it is already busy communicating with the Iridium network. To
hang-up simply press the Send button again.
When a call is being initiated by the ISAT, the user will hear a periodic beep. If the call fails,
the user will hear beeps to indicate the signal was lost. If the signal is lost, the call will end
and the Activity indicator will go out.
