2.1. POWERING THE UNIT
When configuring/manipulating the unit it is always recom-
mended to have a SIM card inserted even if the SIM has no valid
phone-line information. This would ease the configuration pro-
cess of units prior to inserting a valid SIM card. You can also use
a dummy (only-plastic) SIM card. See the following notes and
warnings.
Note:
.
When there is no external USB power, e-track
TM
will not power
ON if there is not a SIM card in the SIM card slot. Also, re-
moving a SIM card from an unit running without external USB
power will immediately Power OFF the unit. On these situations
the unit will not power ON when pressing the button or when a
programmed alarm goes off. To enable power ON, connect the
external USB power OR insert a SIM card. The SIM card does
not need to be active for enabling power ON.
Warning:
.
When a SIM card is not inserted, the unit takes about one minute
to power ON every time the USB power is reconnected. On this
state,
GPS
and
netwrok
LEDs blink while
system
LED is OFF.
This is a Diagnostic state on which the unit is not functional.
Note:
When all LEDs are OFF the unit is OFF. The unit may be OFF
because:
1. It was turned OFF with a long-button-press.
2. A programmed sleep timer went OFF.
3. A remote turn-off command was used.
4. The unit is not connected to the USB power and a SIM card is
not inserted.
5. The internal battery is out of charge.
On the first three scenarios the unit is not really OFF, it is in a very-
low-consumption Alarm mode. In this mode the unit can be turned
ON by a button press, magnetic switch state change, USB-charger
connection or by a programmed time alarm.
