Specifications of NL1-C ANTENNA

• Lead Free Status / Rohs Status: No

<Antenna in Parallel>
If more than one NL is used in parallel or side-by-side, make sure that
the distance between the antennas is at least 4 cm.
<Maintenance>
Make sure that the antenna is free of oil, dust, or rust, otherwise
the antenna may not operate.
Application in Locations Subject to Water or Oil.
Do not use the NL in places where water or oil (especially water-
soluble oil) is frequently sprayed to the NL or antenna, otherwise the
NL may malfunction.
