3. Close SD card cap again. Check that this rubber cap is correctly fitted, avoiding any
partial insertion which may allow water or dust getting inside the device.
2.2 TURN ON and HOLD
Keep the ON button pressed for 2 seconds to start the system. Carry out the same operation for
turning it off.
When the device is on, you may use the button
„
hold‟
to block the device on two levels:
Keypad block
: With one brief press on the „HOLD‟ button, the keypad and the screen
are blocked, making the use of the device impossible, but leaving the screen on.
Repeat a brief pressure to unblock.
Complete blocking
: By pressing for 2 seconds
on the „HOLD‟ button, the keypad will
become blocked and the screen won‟t just be blocked, but also will be turned off.
Consequently, the information will not be visible, but the battery energy will be saved.
Press longer once more to unblock.
2.3 Battery Recharge
The TwoNav Aventura Li-on battery is recharged via the USB port. It is normally fitted with 3
power sources:
PC
: When connecting the device to a computer, besides allowing you to manage the
data present in the memory from the PC, the battery is also charged. The charging
speed will be considerably lower to the other two charging systems (about 12 hours for
a complete charge).
Charger for car lighter
: Included in the TwoNav Aventura kit. If it is charged with the
device turned off, it will take from 4 to 5 hours for a complete charge. If navigation is
being carried out, it will take longer.
AC/DC charger
: Not included in the series. It can be purchased separately or use any
other USB charger. A 1000mA/h charger will take about 4 or 5 hours for a complete
charge.
You can operate normally while the TwoNav is connected to the power source, except
if it is
connected to a PC
, when the device will only operate as a massive storage unit.
Note
: In order to enhance the autonomy of your Aventura, you may purchase the AA battery
accessory with which you can substitute the Li-ion battery by three AA batteries.
