Battery Compartment
The receiver makes use of a rechargeable Li-Ion battery pack.
Loosen the quarter-turn screws [15] [16] using the stylus (or
a coin) to access the battery compartment [17]. The two
screws use opposite directions of rotation for opening and
closing the trap door.
The battery compartment can also accommodate a SIM card
[18] and a micro SD card [19].
When putting back the trap door, insert the bottom first, push
the trap door against the back of the receiver and seal the
battery compartment by fully rotating the two screws in the
opposite direction.
Information on battery charging: see Internal Battery on
page 13.
Bottom View
The bottom view provides access to a standard mini-USB
connector [20]. You first need to open the protective rubber
flap [21], using a finger nail or a sharp and rigid tip to pull
the flap from its left-hand side.
The mini-USB port is used to connect the receiver to the AC
adapter, for a fast battery charging cycle, or to a computer for
file transfer through Microsoft ActiveSync. In both cases, you
need to use the USB cable provided.
Information on battery charging: see Internal Battery on
page 13.
The bottom part of the receiver also accommodates a Reset
button [22], which is accessible after you have opened the
rubber flap [21]. Should the receiver get stuck, you can press
that button using a sharp tool to restart the receiver.
Warning! Never use the Reset button while the receiver is
operating normally or you would definitively lose all the data
you are collecting.
The bottom view also shows the two recesses [23] in which
the hand strap [24] can be anchored.
