The device functions vary depending on model.
Read the relevant precautions for the provided function before using the device.
Precautions for
• When initially operating this device, it is recommended you warm it up for over 15 minutes
under a clear open sky and open area.
• If the vehicle equipped with this device is not used for 7 days or longer, the data storage
recharger inside the GPS may be discharged and require warming up time of over 15 minutes.
• GPS signals are high frequencies around 1575 MHz so they may be affected by bad weather,
such as rain and fog, and electromagnetic interference and the reception rate of the GPS may
deteriorate.
• When the GPS receiver is under an elevated road, inside a tunnel, in a densely built-up area
or near a high-voltage line, it is difficult to receive radio waves so GPS reception may fail.
• The GPS receiver may not work normally in some vehicles with UV coating, sun-block
coating or electromagnetic interference.
