2.3 Helpful Tips
- It’s better to turn off the 887 when you don’t use it, or the serial Flash's life
can’t last long.
- Some vehicles having heavy metallic sun protecting coating on windshields
may affect GPS signal receptions
- Driving in and around high buildings may affect GPS signal receptions.
- Driving in tunnels or indoor park may affect signal receptions.
- 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.
- Low battery of a PDA or of an 887 may affect signal receptions.
- Please check the correct “COM” and “Baudrate” of your PDA.
- 887 output data updates every second, therefore the actual position and the
position shown in your map may have slight time delay. This may happen
when you drive at higher speed or make a turn around a corner.
- Note that 887 may not work indoors where it can not see the sky.
- For the 1
st
time you use the 887, it will take 1 to 3 minutes to obtain the
satellite constellation information and fix your position, this is called “Cold
Start”. If you replace the battery, 887 will do Cold Start again.
- If your 887 can’t fix your position for more than 20 minutes, we suggest you
change to another spot with open space and then try again.
