Recharging The Battery - Seac GURU HP User Manual

Recharging the battery

The SEAC Transmitter has a Li-Ion rechargeable battery with
no memory effect. The battery time data provided can vary +/-
15% depending on the ambient temperature.
m WARNING!
Always fully charge the battery before using the computer
the first time.
You can recharge the Transmitter by connecting it to a USB
wall charger (not included) with the USB cable provided with
the GURU. (The USB cable is not included in the Transmitter
package.)

We recommend using a USB wall plug (like those for
smartphones/tablets) for charging the Transmitter.
If you decided to use a USB port on a computer, make sure
that the computer does not suspend power when it switches
to stand-by mode. Charging the Transmitter from a computer
is not recommended because the device might not charge fully.
2 2
The Transmitter has approximately 100 hours of diving battery
time (this can vary +/-15% depending on temperature) or 2
years in standby (if the battery was fully charged before it was
stored).
Even if the SEAC Transmitter's next-generation battery has
no memory effect, we still recommend charging the battery
completely. Average charging time is 3-5 hours depending on
the residual charge level.
When charging, the SEAC transmitter activates the BLUE LED.
The blue light switches off when charging is complete. Once
the battery has charged, even if the device is left connected to
electrical power, the Transmitter automatically interrupts the
flow of power. If you leave the transmitter charging for longer
than necessary, and leave it long enough that the Transmitter
battery percentage drops below 95%, charging (and the blue
light) will reactivate automatically to charge the battery back
to 100%.
Nevertheless, we do not recommend leaving the Transmitter
on the charger for more than 8 consecutive hours.
m WARNING!
Don't leave the Transmitter with a completely dead battery
for long periods (e.g. 1-2 months); this can damage the
battery. The Transmitter memory records an alarm if it is
left dead for long periods. This eventuality is not covered
by the warranty. If you need to store the Transmitter for
an extended period, first charge the battery fully and
remember to recharge it from time to time.
