E.F. Johnson Company 4100 SERIES Operating Manual page 72

Rekey Fail - Either the rekey command failed or
timed out (after approximately 30 seconds). This
message could indicate that the rekey request
message was not received by the KMF. However,
depending on the KMF configuration and channel
traffic, it is possible that the message was received
and a response is still pending.
Rekeyed! - The rekey session initiated by the radio
was successful.
Additional Functions Selectable by 4100 Menu:
(To select one a parameter, highlight it and press
F2.)
Rekey - Performs the same function as the OTAR
Rekey Request option switch described in the
preceding section.
SECURE COMMUNICATION (ENCRYPTION)
Need KEK - Sends a request for a new KEK (Key
Encryption Key). Upon receiving this message, the
KMF marks the radio as requiring service. One time
this function may be selected is if the radio dumps it
keys.
Identify - Sends a message which tells the KMF that
the radio is on the air. Currently, the KMF always
responds with "No Service", even if the keys are not
up to date. If "No Ack" is displayed, the KMF may
not have received the message (see preceding
section). This function can be used to test communi-
cation without initiating the rekeying that occurs
with the preceding "Rekey" function.
Erase Keys - Erases all keys in the radio the same as
the Erase Keys option switch described in the
preceding section.
