1. OVERVIEW
Altina GBT708 Bluetooth wireless GPS Receiver is a total solution GPS receiver with
Bluetooth, UART interface and built-in rechargeable battery for high sensitivity to tracking
signal. GBT708 is a dual-function GPS receiver. Not only transmit satellite information
through the PDA or Notebook with Bluetooth interfaces but also G-Mouse GPS receiver
through a data cable.
GBT708 provide you various applications such as car navigation, mapping, surveying,
security, agriculture and so on. GBT708 communicates with other device through Bluetooth
wireless function and compatible interface of RS-232 or USB. Indeed, built-in
rechargeable Lithium-ion battery offer you a convenient use in drive and also can save
satellite information such as the status of satellite signal, the last location, date and time for
last use.
With low power consumption, the GBT708 can track up to 12 satellites at a time, and
re-acquires satellite signals in 100 ms and updates position data every second.
Trickle-Power allows the unit operates a fraction of the time and Push-to-Fix permits user to
have a quick position fix even though the receiver usually stays off.

Problems Reasons Methods
Weak or no GPS signal can
be received at the place of
GBT-708
Connect an external antenna, which locate as a
open space to your GBT708 and then run
GPSViewer Cold start function.
No position output
but timer is counting At outdoor space but GPS
signal is blocked by building
or car roof.
Go outdoor and run GPSViewer Cold start
function to try again, or connect an external
antenna to improve the poor GPS signal.
Execute fail Bluetooth function unstable Power On/Off GBT-708. Re-Start PDA or PC and reference sec 5.2
re-install software
Can not turn on the
COM port
Install GBT-708 incompletely
or operate the device is
being used with same COM
port
Install GBT-708 completely or stop other device
that is being used.
Can not find out
