Air Interface encryption (optional)
This service protects communication between the radio equipment and the infrastructure

support this service.

400 are: TEA1, TEA2, TEA3.

End-to-end encryption (optional)
This functionality is particularly interesting for those users who regard their transmissions
as very sensitive, and whose Security Policy requires all such data to be appropriately
encrypted whilst in transit between the end terminals in any system.
End-to-end encryption addresses these concerns by encrypting data within the
transmitting terminal, and only decrypting it within the receiving terminal(s). The plain text
user data is never exposed within the infrastructure.
Batteries and accumulators
If your terminal includes End to End Encryption option, it may have a
3.6 V lithium battery, with low self-discharge rate.
In case you need to extract the battery from the terminal, consult
your official dealer.
Don’t dispose of these products as unsorted domestic waste.
