Ubisense – Ultra-Wideband Location System – Ubitag V2.2
Installation and Operation Instructions
Switching the Ubitag on for the first time
The Ubitag is supplied with a battery, which needs to be fitted prior to operating the tag.
Fitting or replacing the batteries in the Ubitag
The Ubitag uses a Panasonic CR2477 3V lithium coin cell (or equivalent). Ubitags frequently
report their battery health to the system via the Ubisensors, so system administrators should be
notified by the system when the battery in a particular tag requires replacement.
To replace the battery in a Ubitag:
1. Unscrew the four screws in the back of the enclosure
2. Remove the rear of the enclosure to allow access to the battery
3. Slide out the old battery and dispose of carefully
4. Replace the battery with a new one, being careful to observe correct polarity
When the battery has been replaced, the Ubitag will flash its LED to indicate correct start-up, and
the Ubisense Location System will then be able to determine the Ubitags’ location.
Replace the PCB back into the front of the enclosure, replace the rear enclosure half and then
tighten the four screws removed previously to complete reassembly of the device.
Should the Ubitag not flash its’ LED to indicate correct start-up after the battery has been
replaced, remove the battery, check that it is fresh, wait for 30 seconds, and reinsert the battery.
Contact your system administrator if you continue to have problems replacing the battery in the
Ubitag.
