Notice
Although GeoRef V2 series handheld is made of corrosion-resistant and impact-resistant
materials, this kind of sophisticated instrument still needs careful usage and maintenance.
Please preserve the handheld in dry environment as possible. To improve the stability and
service life, the handheld should avoid being exposed to extreme environment, such as
damp, high temperature, low temperature, corrosive gas or liquid, etc.
To ensure the continuity and quality of satellite tracking, the space over observation site
should be as open as possible, without large obstacles over 15° elevating angle. To reduce
various electromagnetic interference to GPS satellite signal, please make sure no strong
electromagnetic interference in 200m range around the observation site, such as TV tower,
microwave station, high-voltage transmission. To avoid or to reduce the multi-path
influence, the site should be set far away from the terrain and ground features where the
electromagnetic wave signal reflection is strong, such as high buildings, large area waters,
etc.
