JRC Handy Search NJJ-95B Instruction Manual page 41

Point the antenna surface in the direction of the probed object (concrete) while you are
performing a probe.。
If it is pointed into the air or otherwise unsuitable direction, it can cause malfunction of other
equipment or other such accidents.
Do not use the NJJ-95B in the vicinity of a radio or TV set.
Doing so may cause noise or poor reception such as disturbance of television pictures. Doing
so also adversely affects the depth sensing capability of the radar, and may cause the cutting
of reinforcing steel bars.
Do not use the NJJ-95B near a cell phone or transceiver that transmits electromagnetic
waves. Electromagnetic waves from the cell phone or transceiver adversely affect the depth
sensing capability of the radar, and may cause the cutting of reinforcing steel bars.
When the NJJ-95B is used for scanning on the road, take safety precautions such as
providing guard fences to prevent traffic accidents.
