Battery
Warning! RISK TO PERSONAL SAFETY.
TETRA radios have been
tested and certified using Sepura approved batteries. The use of non-
approved batteries may damage the product, will result in non-compliance
with regulatory requirements, compromise the product safety ratings, reduce
the length of operating time and will invalidate the product warranty.
Rechargeable batteries have a limited number of charge cycles and may eventually need to be
replaced. Sepura recommends replacing batteries every two years or after 500 charge cycles.
Always replace batteries with an approved Sepura battery of the correct type for the hand-portable
radio.
