Columbus V - 990 Mark II, Руководство пользователя, Страница: 13 / 40

This device is built in with a MTK 66-channels, -165dBm highly sensitive super single chipset. It can easily fix
positions at most places in your car. If you bring it with you, you also can use it to fix positions in relatively
unfavorable outdoor environments. For the first time, it uses the EPS* technology to improve the GPS
position accuracy and, in certain degree, reduce the drifting.
*EPS stands for Enhanced Positioning System, a positioning technology we have specially developed for
the device.
It is recommended to place the device:
●
In the supplied protection case;
●
On a shelf or anti-slip pad under the front/rear windshield in your car;
●
In your backpack or in an outer pocket of your clothes.
Do not use the device at the following places:
At the following places or locations, the device can fail to fix positions or its storage and maintenance can be
adversely affected. Avoid using the device at such places wherever possible.
●
A place at the window within a house, or in a tunnel, or in the shadow of a cluster of buildings; or
under a viaduct, among tall buildings, or in a narrow street surrounded by buildings;

An extremely cold, hot, or wet place. For example, if the device is placed in a car directly exposed to
the sunshine, the high temperature may cause deformation or malfunction of the device;
●
A place on a platform where the device is easy to slip or fall in your car or a place at the airbag in the
car;
●
A place near a strong magnetic field, such as that near high-voltage cables;

A place near a device that generates RF signals of the same band as the device: a place near a RF
device in 1.5GHz band;
●
The device is a precision device. Avoid using it at sandy or dusty places. Keep sand or water out of the
