Warnings
Care and Caution
The Global Positioning System (GPS) is operated by the United States
Government which is solely responsible for the accuracy and continued
operation of the system. Accuracy of position fixes (longitude, latitude and
altitude) can be affected by alterations made to the GPS satellites by the U.S.
Government. Accuracy is subject to change in accordance with the U.S.
Department of Defense civil GPS user policy and Federal Radionavigation Plan.
Positional accuracy and time to fix time can also be affected by poor view of
caused by obstructions such as
tall buildings,
heavy foliage,
large cliffs and other obstructions
where GPS satellite signals are blocked and poor satellites geometry conditions
result.
Judgment
The CRUXII / GPSJAQ receiver is an excellent navigation and location
awareness assist tool, but does not substitute the needs of careful steering and
good judgment. Never only rely on one single tool or apparatus for positioning
and navigation.
Accessories
There may have accessory supplied with the CRUX II / GPSJAQ receiver which are
specifically designed for the CRUX II / GPSJAQ. Use of other accessories will severely
degrade performance or even damage the receiver, and will void the warranty. Do not
try to open or break the receiver. There is no service accessory part inside the
receiver. Open the receiver will void the warranty.
Software
Follow the operation guidance as stated and described in the user guide of the
GPS application software.

Basic Guidelines
SAFETY
Read the User Guide and these basic guidelines comprehensively. Breaching the
regulations and rules may be dangerous or illegal. Road safety is the first priority; do
not use or operate the CRUX II / GPSJAQ receiver while driving. Keep the CRUX II /
GPSJAQ receiver away from high temperatures and fire. Additional detailed
information is given in this user guide. (Consult more details in “Warnings” section)
PROPER HANDLING
Operating the GPS receiver requires a clear and unobstructed view of sky with the
antenna facade pointing upward to the sky. Do not bend the CRUX II / GPSJAQ
receiver while connected to charger, bending will damage the connector, resulting in
damage to the CRUX II / GPSJAQ or the charger’s plug.
FIRST TIME OPERATION
A longer than normal time-to-first-fix of position may result the first time you use the
CRUX II / GPSJAQ. Follow this user guide and consult the instructions of the iPAQTM
Pocket PC and the GPS application software. The CRUX II / GPSJAQ is designed for the
iPAQ Poc ket PC u s e, DO NOT T RY TO FIT OR TO CONNECT THE CRUX II / GPSJAQ WITH
OTHER TYPE OF PDA or OTHER HOST DEVICE.
INTERFERENCE
GPS receivers may receive interference near cellular base-station and when in close
proximity to mobile phone antennae. This interference may affect positioning and
time-to-fix performance.
CONNECTORS, JACK and CF SLOT
There are one external antenna port connector(MCX-female type), one DC power jack,
and one CF slot(for CF Type I and Type II). Caution and care must be exercised when
handling these parts. Bending or breaking these parts will severely degrade
positioning performance as well as damage the receiver and this will void your
warranty.
ACCESSORIES
There may have accessory supplied with the CRUX II / GPSJAQ receiver which are
specifically designed for the CRUX II / GPSJAQ. Use of other accessories will severely
degrade performance or even damage the receiver, and will void the warranty. No

Prepare to use your CRUX II / GPSJAQ Receiver
To help you begin to use your GPSJAQ, read this User Guide in the first step. The User
Guide explains the detail how the GPSJAQ operates, functions, and common features
of the GPSJAQ. A short glossary of GPS related terms and abbreviations at the back of
the User Guide.
Before you begin using your GPSJAQ, you must complete the GPS/MAP application
software installation tasks in your iPAQTM Pocket PC. For information about the iPAQ
Pocket PC operation and application software installation, please refer to the
documentation that accompanies each product.
For operation detail information, please consult Chapter 3. In order to get more
familiar with your GPSJAQ, please first read Chapter 2 before starting to operate the
GPSJAQ.
GPS signal reception
The Global Positioning System (GPS) is a space-based radio-navigation system. This
system consists of 24 satellites, which orbit the Earth at an altitude of approximately
17,500 kilometers, and ground control stations. Each of the 24 satellites, deployed in
6 orbital planes, circles the earth twice a day. The system satellites continuously
transmit signals contain the information of time and distance in a precise formation,
24 hours a day in any weather condition, everywhere around the world. By processing
the signals received, GPSJAQ provides users with helpful information of position,
velocity, and time for navigation and location awareness purposes anywhere anytime
on the Earth.
The GPSJAQ offers high position accuracy and fast Time-To-First-Fix (TTFF), which rely
on environment circumstances where receiver located as well as initial states of the
receiver. During attempting to a position fix, the receiver needs to lock on to at least
3 satellites and, uses the signal can be received as well as the data of latest position
stored in the receiver’s digital memory in order to compute the location of the device.
Environmental factors that influence the position accuracy and TTFF including such as
tall buildings,
narrow street and passageway,

11
protection film on glass,
heavy foliage,
large cliffs,
and other obstructions where the satellite signals may blocked, and, poor satellites
geometry situation. Initial state of the receiver, means latest status in memory of the
receiver, may mainly determine the time of TTFF. Position can possibly be quickly fixed
within only 10 seconds from a hot-start state and needs 80 seconds typically from a
cold-start state. Or, might need at least 3 to 5 minutes from a completely restart-state,
for example, flying a distance over 500 kilometers from initial origin.
The GPSJAQ uses the satellite signals to calculate an exact geodetic location through
triangulation method, contained in 10 meters CEP accurateness devoid of Selective
Availability (SA), which is good enough for general location awareness purposes. The
position data is then converted within the receiver to latitude and longitude
coordinates, which is usually provided in the geodetic datum on which GPS is based
(WGS 84). Position offsets of hundreds of meters or much more can result from using
the wrong datum.
In addition to datum used, there are number of positioning errors can occur, limiting
accuracy. The major errors including satellites orbiting error, poor satellites geometry,
multi-path signals, atmospheric delay and receiver clock timing.
Using optional external active antenna*
An optional external active antenna is for convenience usage when operating under
certain environment situation, such inside vehicle where satellite signals are blocked.
Detailed operation is described in the Operation chapter. Make sure using the optional
external antenna supplied by EMTAC. Use of other antenna will severely degrade
positioning performance or even damage the receiver. Read basic guidelines before
using optional external active antenna accessory.
*External active antenna is an optional accessory which not included in this package.

External antenna port
Your GPSJAQ is equipped with a RF connector port (MCX type) for connecting with
external active antenna(optional accessory) when operating under certain
environment situation, such as inside a vehicle and where satellite signals are blocked
or obstructed. The external antenna port is indicated as in Figure 4. Make sure using
the optional external antenna supplied by EMTAC. Use of other active antenna will
severely degrade positioning performance or even damage the receiver. Please read
basic guidelines before using the external active antenna accessory.
