Chapter 3. Technical specifications

waiting period must happen before inserting new batteries. New batteries should be placed between

the battery springs. Check that the polarity of the batteries is correct. There are battery polarity

indicators on the circuit board and inner surface of the front cover. The correct polarity is also

showed in photo above. Avoid touching the circuit board and the flex cable when replacing batteries

as they may become damaged from static electricity or mechanical impact. Please note that

when battery is empty, voltage will rise after some time and tag will try to power up. As a result,

you will hear ticking sound from the tag and this sound will stop only when both batteries are

removed and both replaced at the same time (A4).

Recommendations for choosing and replacing batteries:

 Always use only new 3V Lithium LiMnO2 CR2 size batteries

 Replace both batteries at the same time (only one back up battery used in A4+)

 Ekahau recommends batteries from ANSMANN, EVE or VARTA as they have been tested

during the development of the product. Any standard 3V Lithium LiMnO2 CR2 could be used but

the performance may vary depending on the quality of the battery.

After batteries have been replaced close the back cover, replace and tighten the screws.

3.4 Care and Maintenance

 Keep the tag dry. Precipitation, humidity and all types of liquids or moisture can contain min-

erals that will corrode electronic circuit

 Do not use or store the tag in dusty, dirty areas. Its moving parts can be damaged

 Do not store the tag in hot areas. High temperatures can shorten the life of electronic devices,

damage batteries, and warp or melt certain plastics

 Do not store the tag in cold areas. When it warms up (to its normal temperature), moisture

can form inside, which may damage electronic circuit boards

 The operating temperature of the tag is 0 to 50 ºC. Do not operate the tag outside this temper-

ature range

 Open the tag only for replacing batteries

 Do not drop, knock or shake the tag. Rough handling can break internal circuit boards

 Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the tag

 Do not paint the tag. Paint can clog the moving parts, affect the radio communication and

prevent proper operation

 Use a soft, clean and dry cloth to clean the tag

 Use only the supplied antenna. Unauthorized antennas, modifications or attachments could

damage the tag and may violate regulations governing radio devices
