Trekker 2.7.3
8.1
General Description
The Trekker application was designed to be used as an orientation aid to find your way in urban and rural areas. Trekker uses a combination of the
Global Positioning System
(GPS) and
digital maps that let you know your location, anywhere in the world where maps are available. A wide variety of maps are available covering North American and European countries.
Maps can be bought online and downloaded from HumanWare's website, or ordered and delivered on CD.
CAUTION:
TREKKER IS NOT A MOBILITY DEVICE. The Trekker system is designed as an ORIENTATION AID, and must not, at any time, be used as the only aid while traveling. A
conventional mobility aid should also be used. It is the user's responsibility to use this device with caution.
8.2
GPS - Global Positioning System
GPS, or Global Positioning System, is a navigation system that is composed of satellites orbiting the Earth. Satellites send signals to the GPS receiver on your Trekker unit. It takes a
minimum of three satellites in order to determine your position. The more satellites, the better accuracy you will have. The signals have weakened by the time they reach street level. If
you are walking in an area surrounded by tall buildings or along narrow streets, you may experience accuracy or signal coverage problems. Operating Trekker indoors or under a roof-like
projection can disrupt the signal, affecting reception. Satellite rotation, time of day, day of the week, and year can also impact GPS signal reception. Lack of accuracy can affect Trekker's
ability to detect intersections and Points of Interest. An intersection may be detected before arriving or when it is already engaged. Points of Interest should be detected within a radius of
10 meters (30 feet). GPS accuracy is currently more or less 10 meters (30 feet).
CAUTION:
GPS is maintained and managed by the Government of the United States of America, who is entirely responsible for its precision and maintenance. The system may, at any
time, be modified and therefore affect Trekker's performance. The GPS signal is not precise or may not be accessible at all times, especially when traveling in an area surrounded by tall
buildings or along narrow streets.
8.3
Trekker Bluetooth GPS System
The Trekker Bluetooth GPS System consists of a Bluetooth GPS receiver, an external speaker, and an optional strap. See the External Devices Section for details.
The GPS receiver comes in a Velcro top closure genuine leather case and can be attached to your clothing or the strap’s belt loop with a belt clip. In addition, it can be secured to your
clothing or the strap with a bungee-cord spring-loaded clip. The GPS receiver should never be covered and always be positioned, facing the sky, over any clothing and preferably as
close as possible to your nape. Make sure that the GPS receiver is located on the back of your neck, or on top of your shoulder.
NOTE:
Bluetooth GPS technology is advancing rapidly both in performance and precision. We are keen to offer our users the ability to try the most advanced receivers available and a
way to test the ones that can better fit a particular need or behave more appropriately in certain geographical situation. Trekker has been tested extensively with the RoyalTek GPS, this
is why this unit is shipped with Trekker. However, we include a list of other compatible receivers, including some based on the recent SiRF Star III chipset. We do not guarantee the
performance of those alternate GPS receivers with Trekker but the users will be able to experiment with them.
Following is the list of Compatible GPS receivers: RoyalTek Mini RBT-1000 ST (R), Holux GR230 (R), Holux GPSlim236, Fortuna Clip-on, Fortuna Slim Bluetooth GPS, Earthmate,
BlueLogger, Globalsat BT-338, Royaltek RBT-2001 and Garmin GPS 10. Note that the (R) symbol means recommended. Visit our Website at
www.humanware.ca
for an updated list of
supported GPS receivers.
The External Speaker is connected to the audio jack, located at the top left edge of the PDA using an audio cable. It can be attached to your clothing or the Trekker strap’s belt loop with
a spring-loaded clip, preferably as close as possible to your ear.
Note that the PDA, the GPS receiver, and the external Speaker can be used with or without the strap, when using without the strap make sure that they are properly attached to the
appropriate locations.
The provided PDA Genuine leather case is used to secure and protect the PDA. It can be attached to your clothing with a built-in belt clip or to the strap using a fixing hook. Once
installed, the PDA will hang upside down so that its buttons are easily accessible. The two elastic bands on the right side of the case are used to attach the audio cable surplus part. To
remove the PDA from the case, unplug the audio cable, unfold the PDA case’s flap, and remove the PDA. The strap can be worn over your shoulder or around your neck.

Using Trekker outdoors
Before using Trekker, verify if the GPS Receiver, External Speaker, and PDA are properly attached, powered On and their batteries are fully charged. The storage card containing the
map of your current area is properly inserted in the card slot of your PDA.
Make sure that the external speaker is attached as close as possible to your ear. Furthermore, ensure that the GPS receiver is attached on the back of your neck, or on top of your
shoulder. Because it is Bluetooth enabled, verify that the PDA Bluetooth Radio is On. See the Bluetooth Section for details.
To Start Trekker press the
System Bar
button to activate the
System Menu
, select
Trekker,
and press
Enter
, or
F4
.
Go outdoors, or place the unit by a window, and power On the GPS receiver, and wait until the GPS connection is established. This operation can take several minutes for the first
connection.
When Trekker establishes the connection, it will begin beeping to indicate that it is detecting your current position. Trekker will then announce the name of the street you are currently on.
If Trekker continues to beep, but no street is detected, try moving up the street to ensure that you get a good signal. You can also press the "
Where am I?"
button (the
Home
button on
your PDA) to get your position information.
