battery adapter is installed in the receiver and transmitter
assembly, place the battery tube inside the clothing so that
body heat of the operator will keep the battery warm and
allow the mine detector set to function properly. Allow a
2-minute warmup time before operating set. When the
mine detector set is taken inside a heated building after it
has been exposed to extreme cold, moisture will form on
the metallic surfaces. Wipe all moisture from the
equipment before securing in the case.
2-12. Operation in Dusty or Sandy Areas
When operating the mine detector set in dusty or sandy
area, special precautions should be taken to keep dust and
dirt out of the equipment. Make sure the latches that secure
the case on the transmitter are locked.
