1.  Introduction   
Thank you for purchasing Leadtek GPS LR9553D. Leadtek LR9553D, based on cutting 
edge SiRFStar III technology, is a high performance, low power, 20-channel GPS data logger 
and receiver with wireless capability. As such it is a highly compatible Bluetooth solution with 
extraordinary configurability and sensitivity. Not to forget its appealing ergonomics—sleek, 
round and lightweight. The innovative switch-mode design not only makes for easy activation 
but also enables more power saving when LR9553D is used as a pure data logger which 
records your tracking data from the received GPS signals. It provides users enough space to 
store their tracking data including the altitude, GPS position, date and time- up to 240 hrs in 
the continuous mode. It is not necessary to export the data until the memory is full. LR9553D 
also comes equipped with mini USB interface both for easy charging and for users to be able 
to export their recorded points to Google earth and Google Maps without a hitch. If using with 
your digital camera and the convenient application software*, you can easily integrate your 
valuable photos with the GPS data you have recorded and make them your forever sweet 
memories. 
*The application software enclosed in the Leadtek GPS LR9553D CD-ROM is a very complete 
and easy-to-use tool for you to integrate your photos and the GPS data. Please register on line

10.   Appendix C: Safety Information 
GPS is operated by the US government, which is solely responsible for the system’s 
accuracy and maintenance. Although Leadtek GPS LR9553D is a high precision electronic 
NAVAID, it may still become unsafe under the circumstances of misuse or inaccurate reading. 
Hence there is a certain degree of risks involving the use of these products. In order to reduce 
the risks, please read carefully all the documentation regarding technical specifications before 
using Leadtek GPS LR9553D. When in use, compare carefully the GPS results with all 
navigation information available, including that from other NAVAID, naked eye view, routes, 
etc. For safety reasons, it is necessary to solve all the problems before continuing to navigate. 
Please DO NOT shake or clash this device, and please be aware that the dust-proof and 
water-proof are NOT guaranteed. The rechargeable battery is built inside, so please DO NOT 
detach it from the device arbitrarily. Meanwhile, please DO NOT use this device under the 
circumstances as below: 
1.  In extremely hot, humid or cold environment, for example, under the direct sun or in rain   
2.  Near the strong magnetic field 
3.  In dusty weather

11. Appendix D: GPS FAQ   
Q. Do I have to pay extra charges for receiving GPS signals? 
A. No. Like listening to the radio, you only need to buy hardware (PC+GPS or PDA+GPS) to 
access the service. There is no extra charge.   
Q. I bought a GPS device in Taiwan. Can I use it abroad?   
A. Yes. GPS signals cover 98% of Earth’s surface (except the North and South Poles), so you 
can use it around the world.   
Q. What datum does GPS devices use?   
A. It uses WGS 84.   
Q. What causes time lapses in navigation? My vehicle has arrived at a specific location, but 
why did not the vehicle indicator in the navigation system reach there at the same time?   
A. There are several possible causes: 
1.  Poor reception of GPS signals; 
2.  The processing speed of CPU, RAM and memory card on the PDA; 
3.  Time lapses are inevitable because GPS is updated once a second.   
Q. What kind of navigation software can I use?   
A. Generally you can use any navigation software featuring NMEA1083 as the data output 
format. 
Q. My device has been successfully connected, but why can’t I see GPS signals in Navigator, 
and why does GPS fail to position? 
A. This may be caused by errors in COM port settings. The automatic GPS scan function of 
general electronic maps may lead to failure in GPS positioning. We suggest that you set the 
options manually.   
Q. After using Navigator for positioning, why can’t I find the GPS antenna on the electronic 
map?   
A. Navigator is an application developed by Leadtek to test GPS navigation. After launching 
Navigator, if you press x or go to the map without disconnecting the program, it will occupy 
the GPS antenna’s COM port. In that case, the map is unable to find the device. To solve 
this problem, disconnect Navigator before exiting the program.   

Leadtek GPS LR9553D Bluetooth Data logger & Receiver 
©2007 Leadtek Research Inc. All rights reserved. 25
Q. Why can’t I use GPS at home or near the window?   
A. GPS is for outdoor navigation only, so your device cannot receive GPS signals at home. 
Especially because it usually takes longer to navigate when you use GPS for the first time, 
make sure that you are in an outdoor place with good signal reception. 
Q. When do I need to run Cold Start?   
A. We suggest that you run Cold Start in the following situations: (1) it has been two weeks 
since your previous navigation; (2) the location you want to position is more than 500 km 
away from that of your previous navigation.   
Q. What is the pin code for the Bluetooth GPS?   
A. 0000.   
Q. Do I need any driver to use Bluetooth GPS? 
A. No, you don’t. 
Q. Could you tell me the specifications of your GPS product, such as size, chip version, initial 
booting time and so on?   
A. If you can’t find the information you want in this Installation Guide, please visit our website
