UTC UDI-28 User Manual page 3

Bottom Timer - Time and depth are presented on the screen only for assistance, thus the diver should
take into considerations that he/she must use a diving computer or diving tables.
The main danger in the use of UDI-28 TM is over reliance on the information provided by it. As lies in an
electronic system it might fail spontaneously and unexpectedly due to component, batteries, incorrect
charging or software failure. In addition the UDI-28™ also contains acoustical functions; hence, as an
acoustical device, it can fail at any time due to changing environmental (acoustic) conditions.

Underwater operations are inherently dangerous, and proper safety procedures demand that you never
rely solely on just the UDI-28 TM or any other single instrument, method or mechanism for human
safety or the safety of property.
BATTERIES DISCLAIMER
Lithium Ion Batteries can catch on fire. The UDI-28™ uses Lithium Ion batteries; therefore it should NOT
be left unattended while being charged as THEY CAN CATCH ON FIRE. Proper precautions should be taken
before charging Lithium ion batteries such as having a fire extinguisher ready and placing the batteries in
a fire safe container.
THE UDI-28™ IS NOT A TOY AND SHOULD BE HANDLED WITH GREAT CARE.
Lithium Polymer Charging, Handling, Safety Information
Charging:
Lithium Polymer and Lithium Ion batteries have specific charging requirements and ONLY the chargers
rated for these cells may be used. The best charger for the UDI-28™ is provided in the pack that you
purchased. Other chargers may alter the settings and can damage cells or cause a fire due to over-voltage
charging of cells. We recommend that you use only the charger that was provided with the UDI-28.
Lithium Polymer Lithium Ion cells are a tremendous advance in battery technology for electronic devices.
However, due to the chemistry of lithium cells, there is a possibility of fire if charging is not properly done.
It is unavoidable due to the nature of lithium itself. This is no different from many things we use in daily
life – knives, kitchen cleaners, automobiles, for a few examples – which are inherently dangerous, but
which can be used very safely by adhering to simple rules and precautions.
