2150GR Ground Penetrating Radar
054-140 - Rev. 2
39/36
APPENDIX C - OPENING MANHOLES
This phase is normally performed once the acquisition phase has been completed, and
consists in opening the manholes present in the investigated site. The data regarding the
depth, diameter, and direction of the utility should be saved on the work sheet: this will
provide you with further reference data during the interpretation phase, and will allow
propagation velocity estimates to be performed in order to calculate the depth of the
identified utility as precisely as possible.
APPENDIX D - CARE, MAINTENANCE AND SAFETY WARNINGS
At the moment of sale, the 2150GR is guaranteed to be free of any defects that may render it
unusable. Its characteristic level of quality respects all the European Community regulations
for electrical safety and electromagnetic emission levels.
Any breakdowns or faults experienced by the user during the guarantee period (after sale, or
under a maintenance contract) should be reported immediately to Subsite Electronics. The
problem will be resolved according to the contract in operation. In any case, only
breakdowns caused by faults in the system, and not those due to its improper use will be
repaired. If the system has been used improperly, Subsite Electronics will not be held
responsible for any damage caused to persons or objects.
The correct use of the system is governed by the following regulations:
¾ No operator, apart form a specialized personnel authorised by Subsite Electronics
may open and/or tamper with any of the groups that make up the system; it is also
forbidden to break the guarantee seals: this operation will mean that the user loses
the right to free technical assistance.
¾ All cable connections must be performed when the equipment is switched off; in
any case, before performing any modification, check that the battery is disconnected
from the radar Control Unit. The operational functions may only be performed once
the entire system has been correctly connected using all the cables.
¾ Always use batteries supplied or approved of by Subsite Electronics.
¾ While the system is switched on, in the acquisition and elaboration phases and
during standby, the antennas must only be in contact with the surface being
investigated. Do not point the antenna towards people. Inspect the cables
periodically, checking that they connect tightly when they are inserted, and that the
external covering of the cable is intact. Never use any cables that show signs of
wear or deformation. Never tamper with the cables by taping them or shortening
them. Contact Subsite Electronics for any repairs.
