5 POWERING THE DSAT-300
5.1 OPERATION FROM BATTERY POWER
The DSAT-300 portable solution runs on two Lithium ION
batteries
(separately charged),
each with its own
integrated
charger.
The
temperature and voltage are monitored separately for each
battery. New, fully
charged batteries operating at room temperature will allow operation for the following approximate timings
(performance will reduce over time):

NOTE:
Use of Bluetooth or Wi-Fi will reduce overall operating time
If running on battery power alone,
the processor will run in a ‘sleep’ mode to preserve power between reports. An
automatic shutdown will occur when the battery voltage has reached its minimum recommended level for operation
(6.0 volts). Whilst operating on battery power a press and hold of the push button will cause the DSAT to start-up
or shutdown, if the battery has enough power to operate.
NOTE:
New batteries are shipped at about 30 to 50% of capacity. Fully charge the batteries before first use and
after battery replacement.
NOTE:
Connecting aircraft mains power to charge the batteries and then disconnecting it whilst in this mode will
cause the unit to shut down. If required the unit can be restarted via the push button to continue operating on
battery.
