• Then push the door against the receiver case and rotate
the two screws back in their initial positions to seal the
battery compartment.
Turning the
Receiver On
• Press the Power key [1] for a couple of seconds until you
feel a vibration in your hand, then release the key.
Let the receiver run its boot sequence. Wait until the
screen displays the Windows Embedded Hand Held
Home screen. Atthis stage, you may be asked to
initialize the receiver (screen alignment, etc.). Just follow
the instructions onthe screen to complete this step.
The operating systemused inthe receiver is Microsoft
Windows Embedded Hand Held.For more information
on how to usethe different applications, you can visit
the Microsoft web site at:
http://www.microsoft.com/windowsembedded/en-us/windows-
embedded-handheld-6-5.aspx
Depending on how long your product was stored in its
package before being shipped to you, the remaining power in
the battery may be too low to allow the receiver to operate for
your entire working session. For this reason, the first thing to
do is to check the battery charge status:
• Tap on the title bar at the top of the screen. The Quick
Toolbar appears just underneath.
• Tap on the Battery icon. This opens the Power window and
simultaneously closes the Quick Toolbar.
The Power window shows the status of the battery (see also
Internal Battery on page 13). If the remaining power is
greater than 50%, thenyou can use the receiver without
having to charge the battery first (with 50% of remaining
charge, you can use the receiver for several hours). Skip
the next section and go directly toAdjusting Backlight
Level and Idle Time on page 4.
• If it less, Spectra Precision recommends you first charge
the battery as explained in Using the AC Adapter to Charge
the Battery on page 3.

Using the AC
Adapter to Charge
the Battery
Follow the instructions below.
• Prepare the AC adapter:
– Remove the protective cover [1] by pushing the button
then sliding the cover forward.
– Choose the plug that fits your country’s AC outlet
standard (see [2]) and slide it into the AC adapter [3].
(A “click” must be heard when fully inserted.)
• Take the USB cable provided [4]. Connect the end fitted
with a standard USB connector to the AC adapter.
Connect the other end (fitted with a mini-USB connector)
to the bottom side of the receiver (open the flap [5] first).
• Connect the AC adapter to an electric outlet. After about
4 seconds, the receiver screen lights up. An icon shows up
indicating that the battery is being charged. The screen is
then turned back off after about 10 seconds. After this
time, battery charging will continue at the same rate until
the battery is fully charged (charging time: 4 hours max.).

• To read the battery charging status using the Quick
Toolbar, refer to the instructions in Turning the Receiver
On on page 2 (see also Using the Quick Toolbar on
page 4).
Using the Quick
Toolbar
Windows offers a quick toolbar allowing you to quickly
access frequently used functions (zoom, Bluetooth, WiFi,
phone, sound volume, battery power and clock).
• Tap on the title bar at the top of the screen. The quick
toolbar appears just underneath.
• Run the desired function by just tapping on the
corresponding icon. This runs the requested function and
simultaneously closes the quick toolbar.
The zoom function enlarges the screen content, which
means only part of the screen is shown at a time, and so
you should drag the stylus over the screen to scroll through
the whole display.
To return to 1:1 zoom, tap on the title bar again to re-open
the quick toolbar, then tap on the zoom function again.
Switching the
Receiver Manually
to Suspend Mode
Switching the receiver to Suspend mode is the right thing to
do when you need to make a short pause in your work and you
want to save the operating time of your battery. You should
not however switch the receiver to Suspend mode when it is
collecting raw data.
In Suspend mode, the receiver is idle, using the minimum of
energy required to save the use context.
To switch to Suspend mode, just press briefly on the Power
button [1]. The receiver screen is turned off instantly.
To wake up the receiver, just press briefly the same button
again. This will instantly switch the screen back on and
restore the use context in which the receiver was before
entering the Suspend mode.
Adjusting
Backlight Level
and Idle Time
Backlight Level: The screen backlight may be adjusted to
match the ambient light for optimized visibility. You don’t
need the same level of screen backlight in dark areas than in
hot sun.
Backlight Idle Time: One way of saving the battery is to avoid
those periods of time during which the screen backlight is
unnecessarily on. As the receiver automatically counts the
time during which neither the keypad nor the touch screen is
active, you can set the receiver to turn off the backlight
automatically after a certain idle time.

English

Follow the instructions below to set these two parameters:
• Press the Windows key and tap successively on Settings,
System and Backlight.
• Tap on the Battery Power tab.
• Drag the cursor to the right or left to set the screen
backlight to the desired level (between Dark and Bright).
The resulting brightness is obtained when you release the
cursor.
•TicktheTurn off backlight if device... check box and then
choose the idle time before the backlight is turned off
(10 seconds, 30 seconds or 1 to 5 minutes)
Note that the backlight level and idle time can be set to
different values for when the receiver is operated from an
external power source instead of its internal battery. You
can make these settings after tapping on the External
Power tab.
•TapOK to save all your changes and return to the previous
screen.
Power
Management
Another way of saving the battery is to allow the receiver to
switch automatically to Suspend mode after a certain period
of inactivity.
• Press the Windows key and tap successively on Settings,
System and Power.
• Tap on the Advanced tab. This tab allows you to ask for the
receiver to switch automatically to Suspend mode if it
stays idle for the period of time you choose. You may
choose a different setting depending on whether the
receiver is powered from the internal battery or from an
external power source.
•TapOK to save the settings and return to the previous
screen.
Remember that the receiver should NOT be allowed to switch
automatically to Suspend mode if it is expected to collect
data for a long period of time and you know the keyboard will
be left idle during this time.
Setting Time & Date
• Press the Windows key and tap successively on
Settings,and Clock & Alarms.
•OntheTime tab, select your time zone and then enter the
local date and time.
•TapOK to save your settings.

English
6
Regional Settings
It’s a good idea to customize your receiver so that it complies
with a number of local preferences, such as country’s
currency, decimal point representation, time and date
formats, etc.
• Press the Windows key and tap successively on Settings,
System and Regional Settings.
•OntheRegion tab, select your country.
• Use the other tabs to set your local settings:
– Number format
– Currency choice
– Time and date formats
•TapOK to save the settings and return to the Today screen.
Locking the
Screen and the
Keypad
At some stage in your work, you may need to lock the receiver
to make sure no user intervention from the screen or keypad
can affect the work in progress.
• Press the Windows key.
• In the task bar at the bottom of the screen, tap on the
padlock icon (see screen below). As a result, the touch
screen and keypad are made inactive.
• To unlock the touch screen and keypad, just drag the on-
screen slide button either to the left or right. This will take
you back to the Home screen.

Advanced Features
Power Modes The receiver has three power modes:
•Shutdown: The receiver is off.
•On: The receiver is fully powered
•Suspend: In this mode, the screen content and backlight
are turned off to save power and the use context is saved.
When quitting the Suspend mode, the use context is
restored instantly. Typically this mode is used in the field
to allow a quick restart after a pause.
The receiver can also enter the Suspend mode
automatically in case of a very low battery after dismissing
successively the two “low battery” alerts, or after an idle
time that you can set through a press on the Windows key,
and selecting Settings, Power (Advanced tab) (See also
Power Management on page 5).
Suspend Mode
The receiver can be switched to Suspend mode. This is a
power saving mode typically used in the field to allow a quick
restart after a pause. In this mode, only some parts of the
receiver are powered for the sole purpose of restoring the
context of use in which the receiver was when it was switched
to Suspend mode. The receiver should NOT however be used
in that mode while collecting raw data.
The receiver can also enter the Suspend mode automatically
in case of a very low battery after dismissing successively the
two “low battery” alerts, or after an idle time that you can set
through a press on the Windows key, then Settings, System and

When the remaining power drops below 10% of full charge
(orange area), you will see the message “Main Battery Low”
prompting you to replace or recharge the battery. Tap Dismiss
in the task bar. You should consider replacing the battery for
a fresh one but you may still continue to use the receiver for
a while.

the task bar to continue using the receiver. Spectra Precision
however recommends that you turn off the receiver and
replace the battery.
With only about 1% of remaining power, the receiver will
switch off, meaning the battery is no longer charged enough
to ensure proper operation of the receiver. Spectra Precision
recommends you do not go that far in the use of the internal
battery as there is a risk of losing part of your field data.
In case of long-time storage, remember Li-Ion batteries must
always be recharged regularly, about every six months. This is
to prevent irreversible damage of the batteries.
