Use of integrated antennas 1 and 2
The transponder has two integrated antennas. Which of the two internal antennas is used can be
configured as a parameter in the Locating Manager by a trained commissioning engineer.
Antenna 1 is configured by default and is used when the transponder is attached to a vertical
surface on the side of the object to be located. The transponder must be attached in such a way
that the Siemens lettering of the battery cover points upwards. Antenna 2 is configured when
the transponder is attached to a horizontal surface. Misconfiguration can lead to a reduction of
the range.

Use approved batteries
Insertion of non-approved or damaged batteries may result in damage to the transponder or its
surroundings. Only use batteries approved by the manufacturer, see section "Technical
specifications (Page 23)". Before inserting a battery, make sure that it is not damaged. The
transponder batteries can only be replaced in dry environments.
Proceed as follows to replace the battery in the transponder:
1. Open the cover by pressing the latch (ribbed surface).
2. Remove the battery to be replaced and wait 30 seconds before inserting the new battery
while maintaining the polarity direction.
3. Close the enclosure again so that it is latched.
