Ubisense – Ultra-wideband In-Building Location System – Ubitag V2.1

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 PCB from 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 bleep once and flash its LEDs to indicate

correct start-up, and the Ubisense In-Building Location System will then be able to determine the

Ubitag’s 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 bleep and flash its LEDs 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.
