3. Operation
3.1. Hardware Description
The Bluetooth GPS has two LED light which each has two colors. One is GPS & Charge
status LED, that is named LED 2, and the other is Bluetooth & low power status LED, that is named
LED 1. The status table of LED shows as follows:
<State Table of LED>
LED1
BT & Low Power LED Description
LED1 Color and Action Bluetooth Active Low Power
Blue Flash Yes No
Purple–Red Flash Yes Yes

LED2
GPS & Charge LED Description
LED2 Color and Action Battery Charged Position Fixed
Dark No No
Green Flash No Yes
Red Yes No
Orange-Red Flash Yes Yes
<Note1>When the Bluetooth is active and LED 1 lights, it shows Bluetooth RF function. As long as
the Bluetooth RF is transmitting the LED light will flash. When Bluetooth doesn’t connect the other
Bluetooth device, the LED 1 will be flash periodically. Therefore, it means that it broadcasts message
to connect the other device with Bluetooth function. If it connects the other Bluetooth device and
transmits data, LED 1 will flash very quickly and look like bright.
<Note 2>When the battery is charging, LED 1 will show purple-red color and flash. The reason that
Bluetooth is working cause LED 1 purple-red color. If the GPS receiver go to the end of charge, LED
1 will show blue color and flash.
3.2. Turn on/off
Turn on To turn on the receiver, press the power button on the topside briefly (0.5
seconds). The left LED(LED 2) indicator will flash briefly. The right LED
(LED 1) indicator will start flashing.
Turn off To turn off the receiver, press the power button on the topside for 3 seconds.
The LED indicator will flash briefly before switching off the receiver.
3.3. Charging
Low Power The right LED(LED 1) indicator will turn RED (normally BLUE) when battery
power becomes low. Connect the receiver to a powers source to continue
operation and to recharge the battery.
Charging The left LED(LED 2) indicator will turn RED (or ORANGE) when the battery
is being charged. When fully charged, the RED indicator will switch off.
3.4. Bluetooth Communication
Waiting to connect The right LED(LED 1) indicator will flash if there is no communication
between the receiver and another device.
Connected The right LED(LED 1) indicator will turn to continuous lighting when the
receiver is connected through the wireless link with another device.

3.5. GPS
Navigating The left LED(LED 2) will flash GREEN (or ORANGE when charging) if the
receiver is able to determine the current position.
3.6. PIN CODE
ThePIN code means Personal Identification Number for Bluetooth device and it is also
called as Pass Key. The Bluetooth GPS receiver has the default PIN Code, and is “0000”. Generally
speaking, there are two steps in Bluetooth connecting. One is pairing process, the other is link process.
If you need PIN code to pairing and connect, you can use the default pin code, “0000” to connect
Bluetooth device. Our GPS receiver belongs to non-safety connecting, you can use in general
application to finish connecting.
4. Notices
4.1. Global Positioning System
The Global Positioning System (GPS) is operated and maintained by the Government of
the United States of America who are responsible for the availability and the accuracy of the system.
Changes in the operation, availability and accuracy may affect the operation of your GPS receiver.
4.2. Aircraft and Hospitals
Use of devices with an antenna is prohibited on most aircraft and in many hospitals. The
TomTom Wireless GPS receiver is a receiving and transmitting device with two antenna’s and should
not be used in these environments.
4.3. Heat Reflective Shields
Modern vehicles may have a heat reflective shield in the windshield, preventing proper
GPS signal reception if the receiver is placed under the windshield. To get proper reception:
(a) Use an external antenna, or
(b) Place the receiver in a different position, or
(c) Attach the cradle to the windshield behind the rearview mirror, where many vehicles have an
opening in the heat reflective shield, indicated by a black outline.

5.5 Battery
This product uses a Lithium-Ion battery. Please charge fully before first use. Operation in low (below 0º
C/32ºF or high (over 40ºC/110ºF) temperatures will affect power supply efficiency and the ability to
charge the battery. All Lithium-Ion batteries will experience power supply efficiency deterioration over
time even if not used and have a limited life expectancy. Permanently powering the battery will reduce
life expectancy. Do not use your product in a humid, wet and/or corrosive environment. Do not put,
store or leave your product in or near a heat source or in a high temperature location and do not expose
it to temperature over 60ºC(140ºF). Failure to follow these guidelines may cause the Lithium-Ion
battery to become hot, explode or ignite and cause injury and/or damage. THE LITHIUM-ION
BATTERY CONTAINED IN THE PRODUCT MUST BE RECYCLED OR DISPOSED OF
PROPERLY. USE ONLY WITH SUPPLIED CHARGER(s) AND SUPPLIED AC ADAPTOR FOR
BATTERY CHARGING.

Appendix A Software Install
iPAQ Bluetooth Setup with Pocket PC software
<Note 1> These steps apply to the PDA with Bluetooth function, for example iPAQ
3870 or 3970 PDA
<Note2> The operation system of iPAQ Pocket PC is Chinese Window CE version
and shows as follow. The English version should be similar with Chinese.
<Illustration> Bluetooth GPS receiver and iPAQ h3970 device
There are several steps to use Leadtek Bluetooth GPS(9537) with PDA (Bluetooth
Built-in PDA or PDA with Bluetooth CF card) for user. Since the version of BTW-CE
(Widcomm Bluetooth Manager) may be different for all PDA, there two operations
introduced in the manual.
1. How to Check The Version of Bluetooth Manager
It’s very simple to check the version of BTW-CE. If BTWCE is installed in the
PDA, there will be a Bluetooth icon ( or ) displayed in the right of the bottom of
screen. The information and the declaration for copyright of BTWCE will be shown
in “about” page.

2. BTWCE 1.1
(1)Make sure that the Bluetooth Device is powered on.
(2)Select “Bluetooth Manager”.
(3)When the Bluetooth Manager is executed, the user can check COM port
configuration. Choose “Tool”, and then select “Setup all Device”. Then in “Serial
Port” Page, the user will see Outbound COM Port which will be used by
application. In this case, the com port is 8.

.

(4)Select “Search” to find target device, then BTW-CE will start to search nearby
Bluetooth device.
Finishing searching and “Leadtek Bluetooth GPS” found, select the target and
save it for selected group. In this case, the target device is saved to default group.
Then click to save the target.

(5)Back to the main form of BTW-CE, if there’re devices saved, the device list
should seen. Then double-click the target device, BTW-CE will start to search the
service provided by the target device for a while. After searching services, if the
device is alive, there should be the name of SPP service on the action list.

.

(6)In this case, “GPS Serial Output” is on the list for the SPP service. Select “Link to
GPS Serial Output” to start to establish the serial link.

.

(7)As the connection being established, the port could be used by application.
(8)Since BTW-CE will remember the last device linked to, the user doesn’t have to
go the previous steps when going to use the Bluetooth device. Applications could
open the serial port directly, and then BTW-CE will smartly try to connect to the
last linked device. However, if there’s other device the user want to use, the steps
should be done again.

3. BTWCE 1.3
(1)Make sure that the status of Bluetooth is on.
(2)Change the page to “Serial Port”, then check which com port used as “Outbound
COM Port”. In this case, the number of com port is 6. And then change to “about”
page, there should be version string shown.

.

(3)Click the “Bluetooth Manager” in “General” page. Select “New” and “Connect!”
to add new device.
(4)Then the Bluetooth Connection Wizard will be executed. Select “Explore a
Bluetooth device” and click “Next”. Tab the Device frame on the form to start to
search.

.

(5)After searching, the found devices will list. Click on the target to find service. If
the SPP service is found, the service name will be shown in Device frame. Then
select the target service and click “Next”.
(6)After the previous steps, the wizard will show the message to tell the user that the
link shortcut has been established. It means that the user could see the shortcut in
the Bluetooth Manager.

.

(7)Select the target and hold on it for a while, then the sub-menu will pop-up. Select
“Connect” to establish the link. If successes, the icon of target device will turn
into green. As the connection has been established, application could open the
port.
BTW-CE 1.3 won’t remember the last linked device. Instead, when the application try to
open the outbound port, if the port is not link to the target previously, then the Bluetooth
Manager will pop-up. And the user would select the shortcut of the target device to
