Authentication Key (A–Key) Programming
This option allows you to program the Authentication key of the phone.
The A–key can
never be read from the phone, only programmed to the
phone over writing the previous value.
To program the A–key a valid A–key plus a valid checksum must be
entered as one complete number.
– Valid A–Key number= 6 to 20 digits (e.g. XXXXXXXXXX)
– Valid checksum = 6 digits (e.g. YYYYYY)
Example:
– A–Key Entry would be XXXXXXXXXXYYYYYY

Writes the highlighted selection to the selected NAM in the phone if A–Key
is valid. Otherwise an error message is displayed.
Write All
