label with compliance markings.

direct exposure to sunlight.

• The tag battery life is approximately 10 years under normal operating conditions. The

tag contains an internal lithium battery and should be discarded according to local safety

requirements.

screws or rivets.

• The tag may be mounted vertically or horizontally

• In some applications, there may be a preferred orientation of the antennas. The circuit

card assembly is located on the sloping face of the case opposite the battery location.

The battery side of the case is indicated by the presence of a rounded bar approximately

0.5 x 5.0mm near the end of that face.
