Restricted Proprietary and Confidential Information
LiON Batteries have a shelf life of approx 2-3 years. Inaccurate handling of the batteries may cause deterioration
of performance or even failure.
Removed batteries:
The batteries should be stored at room temperature, charged to about 30-50% of
capacity. It is recommended that the batteries are charged about once per year to prevent over
discharge.
Installed batteries
: It is recommended that the batteries are charged every 6 months (until two LEDs
are on during charging).
8 PUSH BUTTON
The push button on top of the unit has 2 main functions:
Press and hold (for greater than 4 secs) to turn the unit on/off whilst on
battery power
Press twice in succession for Emergency mode (not available when the
unit is in recharge mode)
9 MESSAGING
The DSAT-300 does not have an interface to compose or read emails, but a mobile device running RDA or STS
Messenger software (requires Bluetooth or Wi-Fi Access Point adapter) can be used to send and receive emails.
If there is an Iridium Satellite communication problem then the DSAT-300 will queue the incoming/outgoing
messages until the queue is full. Once the problem has been resolved the messages will be transmitted in the order
they were received.
If the DSAT is turned off whilst there are messages in the queue it will attempt to send the messages when the unit
is next powered-up. This will continue until the messages are sent. If the message queue is full when another
message is received, the DSAT will send ‘Message rejected, Inbox is full’ to the originator.
10 LOGGING
The DSAT-300 will automatically log and store the latest position data, unprocessed GPS and battery health data
and error logs. This data can be retrieved by SKYTRAC Systems only.
