Checks for the External GPS
Even if the GPS isn’t working the video is recorded, but position coordinates and
driving speed are not recorded. When used for the first time, or when the product
is not used for three consecutive days, it will take some time for GPS to find the
current position.
If the recorded video is checked using a viewer program, or the BlackVue
application, and an error occurs with the GPS time, it is recommended to turn on
and off the power after a GPS signal is received.
Comply with the following for an uninterrupted GPS signal:
y Do not have the windshield glass tinted with a metallic component.
y Be careful with the installation of devices that may interfere with GPS reception
(e.g. some wireless starters & alarms and MP3/CD players).
y Do not use the product simultaneously with other devices that use GPS signals.
y Cloudy weather can interfere with GPS reception.
y GPS reception can be poor when driving under overpasses or in tunnels,
underpasses, streets with skyscrapers or high rise buildings, generating stations,
military bases, or broadcasting transmitters, etc
Checks for the microSD Card
Refer to the following for trouble-free use of microSD card:
y It is recommended to format it on a weekly basis.
y If the recorded video breaks up, format the microSD card.
y In order to ensure the reliable use of the card, format the card by using the
official program recommended by the SD Card Association. For detailed
information, see the website of BlackVue (www.blackvue.com).
y Before formatting it, copy important files to other storage media.
y The microSD card can be formatted in BlackVue without connection to a PC.
(Page 31)
y Insert the formatted microSD card into the product. Then, the microSD card will
be automatically initialized and the firmware installed on it.
y Insert or remove the microSD card only when the product is turned off.
y MicroSD cards are consumables, and warranted for six months.
y If a microSD of another company is used, a compatibility issue may occur.
Therefore, you must use the original microSD card from Pittasoft Co., Ltd.
y If the Battery Discharge Prevention Device(ex. Power Magic Pro) is used,
the microSD may not be able to be used for a long period of time.
y If a 64GB microSD card needs to be used, format it using BlackVue Viewer and
insert it into the product. (Page 32)
