4. Operation manual
4.1. Battery install
Takes down the battery top plate, loads the battery in the battery cavity, again on box
battery top plate.
4.2. charge
The use travel battery charger is the product power supply, this time the green LED
shines, demonstrated the present product is being at the charge condition. When charge
conclusion, the green green LED lantern festival extinguishes, this time may tear off the
battery charger.
4.3. Switch machine
This product power source pressed key belongs guards against the vibration design, the
user presses the POWER key 1 second then to be possible to complete the starting process,
this time the blue color LED lamp quickly dodges prompts the user to complete the starting
process.
The user may long press the POWER key for 1 second to close the GPS module work
(this time product to be at low power condition, connects bluetooth equipment to be able to
stimulate the GPS module automatically power source power supply), if presses the
POWER key to maintain for 2 seconds, then the system can close the system power supply.
4.4. Bluetooth connection
4.4.1 Connect PDA which Integrates the blue tooth equipment
ZYM-GMB21-3 7 of 7
1) start GMB21-3.
2) Refers to PDA's bluetooth user's manual, connects PDA with GMB21-3, when
connection needs to input pairs the password, may input “0000”, until prompts the blue
tooth whether has to establish the COM connection, the choice is“YES”.
3) Inspects the serial communication port which the blue tooth uses (majority of PDA
to tacitly approve for COM6).
4) Turns on the appropriate navigation software, chooses the correct COM port, set
baudrate to 4800 then may use normally.
4.4.2 Connect to Laptop which Installs the bluetooth adapter
1) start GMB21-3.
2) Refers to bluetooth adapter user's manual, connects Laptop with GMB21-3, when
connection needs to input pairs the password, may input “0000”
3) Inspects the serial communication port which the blue tooth uses
4) Turns on the appropriate navigation software, chooses the correct COM port, set
baudrate to 4800 then may use normally.

5. Appendix A Bluetooth connection
Explanation
Step one: Open IVT Bluesoleil
Step two：Single-clicks the central red sphere, searches the blue tooth equipment.
ZYM-GMB21-3 9 of 9
Step three：Double-clicks blue tooth equipment which just searched, searches
service which this blue tooth equipment could provide, this product could provide the blue
tooth serial port service.
Step four: Single-clicks the blue tooth serial port service chart sign, if you are first
time with this product connection, the system possibly can provide must input the password,
may input "0000".
Step five: After the determination, IVT can prompt: My blue tooth portCOM6 (COM6)
already and long-distance equipment establishment connection

Under when the string mouth turns the chart shows the green, indicated this blue
tooth has been allowed normally to receive.
This time may use in the compact disc the GPSView software choice equipment
COMport is COM6, and the baudrate is 4,800, single-clicks opens GPS then to be possible
normally to receive the signal.
