Note
Although eFix R2 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
being used in damp, high temperature, low temperature, corrosive gas or liquid, etc.
To ensure the continuity and quality of the 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 GNSS 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.
Note:
 This equipment contains ESDS (Electrostatic Discharge Sensitive Device), with level
C of electrostatic anti-interference test. To touch, move, or plug the equipment please
follow the ESD (electro-static discharge) instructions.
 Must be used and preserved in the stipulated temperature range. For details, please
refer to the previous chapter: Technical Specifications。

Radio Module
Built-in radio module
eFix R1 is designed with built-in 3G modem, and with internal radio module in standard
package shown as below figure. The transmission power of internal radio module is
0.5W/2W adjustable and air baud rate is 9600, 19200bps, whose working rang can be as
good as 5km.
External radio
For even longer working range, users can use the external radio for eFix R1. Using the
transmitting radio with 35W/2W transmission power for eFix R1 base while the receiving
radio with 2W/0.5W transmission power for eFix R1 rover, both of which are already
packed in the standard eFix R1 RTK set package (base and rover), the working distance can
be as good as 10km or more.
Furthermore, the external radio is compatible with the Pacific Crest PDL radio and SATEL
radio. Then surveyors can easily use KQ e Fix R1 working together with other brand GPS
base or rover.
For more details of external radio, please look into the chapter Appendix: External Radio
