Appendix F� Helpful tips
Your Blumax Bluetooth GPS-4012 Receiver should be treated with care and prop
-
erly maintained to ensure the best performance. Keep in mind these helpful tips
when using your receiver:
- Some vehicles having heavy metallic sun protecting coating on windshields,
which may affect signal receptions
- Driving in and around high buildings may affect signal receptions.
- Driving under tunnels or in buildings may affect signal receptions.
- Low battery of a PDA or of an Blumax Bluetooth GPS-4012 Receiver may
affect signal receptions.
- Please check the correct “COM” and “Baudrate” of your PDA.
- In general, any GPS receiver performs best in open space where it can see
clean sky. Also weather will affect GPS reception – rain & snow contribute
to worse sensitivity.
- Blumax Bluetooth GPS-4012 Receiver output data updates every second,
thus the actual position and the position in your map may have time delay.
This may happen when you drive at higher speed or make a turn around a
corner.
- Note that Blumax Bluetooth GPS-4012 Receiver may not work indoors
where it can not see the sky.
- For the 1st time you use the Blumax Bluetooth GPS-4012 Receiver, it will
take 1 to 3 minutes to get the satellite constellation and fix your position, this
is called “Cold Start”. If you replace the battery, Blumax Bluetooth GPS-4012
Receiver will do Cold Start again.
- If your Blumax Bluetooth GPS-4012 Receiver can’t fix your position for
more than 20 minutes, we suggest you change to another open space and
then try again.
