4 Operation
4.1 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
Orange Yes No
Orange-Red Flash Yes Yes
4.2 Turn on/off
Turn on To turn on the receiver, press the power button on the topside
briefly (0.5 seconds). The right LED(LED 2) indicator will flash
briefly. The left LED(LED 1) indicator will start flashing. Note:
When the Receiver is in the cradle, it will switch on when power
to the cradle is switched on (to synchronize with vehicle ignition).
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. Note: When the receiver is in the cradle, the
receiver will switch off if the power to the cradle is interrupted or
switched off (to synchronize with vehicle ignition).
4.3 Charging
Low Power The left 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 right LED(LED 2) indicator will turn RED (or ORANGE)
when the battery is being charged. When fully charged, the RED
indicator will switch off.
4.4 Bluetooth Communication
Waiting to connect The left LED(LED 1) indicator will flash if there is no
communication between the receiver and another device.
Connected The left LED(LED 1) indicator will turn to continuous lighting
when the receiver is connected through the wireless link with
another device.
4.5 GPS
Navigating The right LED will flash GREEN (or ORANGE when charging) if
the receiver is able to determine the current position.
4.6 PIN CODE
The PIN 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.

5. Notices
5.1 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.
5.2 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.
5.3 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.
5.4 Important
The information in this document is subject to change without notice. No liability shall be assumed for
technical or editorial errors or omissions contained herein; nor for incidental or consequential damages
resulting from the performance or use of this material. This document contains information protected by
copyright.
5.5 Battery
This product uses a Lithium-Ion battery. Please charge fully before first use. Operation in low (below 0
C/32 F or high (over 40 C/110 F) 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 60 C(140 F). 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

reception, which can be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
--Reorient or relocate the receiving antenna.
--Increase the separation between the equipment and receiver.
--Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
--Consult the dealer or an experienced radio/TV technician for help.
CAUTION
Any changes or modifications not expressly approved by the grantee of this device could void the user’s
authority to operate the equipment.
