Regulations regarding the use of the 460MHz radio-modems vary greatly from country to country. In some countries, the unit can be used without obtaining an end-user license. Other countries require end-user licensing. For licensing information, consult your local FOIF dealer. Bluetooth operates in license-free bands.

Nevertheless, the wireless radio shall be used in such a manner that the FOIF receiver is 20cm or further from the human body. The internal wireless radio operates within guidelines found in radio frequency safety standards and recommendations, which reflect the consensus of the scientific community.

This device has been designed to operate with the antennas listed below. UHF Antennas not included in this list, or that have a gain greater than 5dBi, are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. The antennas that can be used (country dependent) with the 460 MHz radio are 0dBi and 5dBi whip antennas.

4) 5m pole is suggested in raising the UHF antenna for better signals. 5) Distance between UHF antenna and A20 should be more than 3m. 6) Considering the safety of yours, A20 is not suggested to be used at the weather of thunder or storms.
Port for ANT Power Amplifer can enlarge transferring distance which is the same function as external radio, but should work together with A20 which has inner emitting radio. Made by FOIF PWR Light Because A20 has many Product Numbers to choose for deciding its configuration.
2. Comfirm that connection between bracket and controller is tight to avoid that controller dropping to the ground. 3. If network is used, then UHF antenna does not need to fix on A20.
A20 User Manual Measuring the Antenna Heights Measuring the Antenna Heights for a Tripod Setup 3.6.1 Ways: Pay attention to the buckle of black rubber fixing around the receiver, use your tapeline from the buckle to the point where your base is setting up, thus the reading on tapeline is the height of base.
Page 25
Considering the normal height of pole is 2m, so while setting the rover, you just only choose vertical height and enter 2m , which is also the default choice, h0 could be add automatically by software (FOIF Survey_GPS). If telescopic pole is used, then 2m should be changed to the actual height of pole.
Bluetooth 1. Connecting work should be done first before start FOIF survey_GPS. Using controller scan the bluetooth signal of A20.When bluetooth is found, the SN of A20 is shown in controller, then select this SN to finish the connecting work.

A20 User Manual Ways of Outdoors Working for Static Surveying 1) Surveyors should give a general understanding about their surveying district e.g. point position, difficulties of making point and also includes the economic level, culture custom, traffic situation etc. at that place.
A20 User Manual GPS Network Network Designing 6.4.1 1) The baselines should be closed. Single baseline is not accepted in the designing. 2) It is not right to say that the more the baselines, the better the results are. Three baselines for one point is suitable for the reliability of network.
Page 51
A20 User Manual Accuracy Standard in Static Surveying 6.4.2 Accuracy standard in static surveying is judged by the rms of distance in the adjacent two points. : rms (mm) : fixed error (mm) : scale factor (ppm) : distance (km) The surveying accuracy for GPS is divided into 6 levels by Surveying Standard for GPS published in 2001 (AA, A, B, C, D, E).
Page 52
A20 User Manual GPS Network 6.4.3 There are many kinds of GPS network designing such as tracking, alternately observation, multi-base, single-base, normal. Tracking: Several receivers fixing at the certain points for a long time observation (such as 1 year without stop), which is suitable for level AA control survey or perma- nent monitoring survey.
Page 53

A20 User Manual Point connecting network is defined as a figure by connect- ing two adjacent shapes by only one common point. The advantages for this type is high efficiency, fast extending, but it also can not confirm the high precision surveying. So it is not suggested in precise working.
Page 55
A20 User Manual Polygon connecting network is defined as a figure connect- ing the two adjacent shapes by at least 3 common points. So this network at least needs 4 receivers. It is better than side racy but not working time. So it is connecting network in accu only suggested for high precision control surveying.
