Appendix F. Helpful tips
Your BT-Q800 should be treated with care and properly 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 BT-Q800 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.
- BT-Q800 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 BT-Q800 may not work indoors where it can not see the sky.
- For the 1
st
time you use the BT-Q800, it will take 5 to 10 minutes to get the
satellite constellation and fix your position, this is called “Cold Start”. If you
replace the battery, BT-Q800 will do Cold Start again.
- If your BT-Q800 can’t fix your position for more than 20 minutes, we
suggest you change to another open space and then try again.
