When tracking mode is enabled, the 3G automatically checks the mailbox each time it
wakes up and successfully sends a position report.
Using the Mbox Rate menu (see below for detailed description), the 3G can be set to
automatically wake up and check the mailbox at a preset frequency. A position report
will not be sent when the 3G wakes up to check the mailbox unless the mailbox check
rate coincides with the tracking report rate.
The
Check Mailbox
menu can either be
Idle
or
Checking
the Iridium gateway for any pending
messages to be downloaded. As the messages are being downloaded, the 3G shows the
number of unread messages in the Inbox and the number of messages still queued at the
Iridium gateway to be downloaded, as shown in the figure below.

The Mailbox Check Rate [
Mbox Rate
] option is available ONLY when the Iridium link is
enabled.
The Mbox Rate is used to set mailbox check rate (time between mailbox checks) and to enable
mailbox checks automatically. Select either a predefined rate or a user-defined rate with an on-
screen keypad. The
Mailbox Check Rate
menu is dimmed when mailbox check is disabled.
However, even when mailbox check is disabled and the labels are dimmed, you can still enter
the rate.
