Field Definitions
Generate Key-Loss-Key Use the UP/DOWN arrow keys to enable/disable this feature. When
this feature is enabled, the radio will be able to generate a Key-Loss-Key
signal from a Unique Shadow Key allowing the radio to be re-keyed via
the Over-The-Air Rekeying (OTAR) feature. When this feature is
disabled and the radio has lost all of its keys, the radio cannot be
rekeyed via the OTAR feature.
OTAR Ack Use the UP/DOWN arrow keys to enable/disable this feature. When
this feature is enabled, the radio will acknowledge all OTAR messages
that request an acknowledgment. When this feature is disabled, the
radio will not acknowledge OTAR messages that require
acknowledgment, except for Rekey Requests initiated via the radio’s
Rekey Request menu.
Note: When this field is set to Disabled, you MUST ensure that all
Stat-Alert features are also disabled. This is to prevent undesired
compromise of security. Stat-Alert features include Radio Check,
Remote Monitor, Auto Selective Call Transmit, Call Alert Decode and
Selective Call Decode.
Note: The OTAR Ack feature is independent of the Power-Up
Ack feature.
Encrypted Only OTAR Ack Use the UP/DOWN arrow keys to enable/disable this feature. When

radio will send encrypted or clear acknowledgments as directed by the
Key Management Controller (KMC).
Power-Up OTAR Ack Use the UP/DOWN arrow keys to enable/disable the Power-Up Ack
feature. When this feature is enabled (that is, set to Immediate or

Ack feature.

the radio menu. If this feature is disabled, rekey requests can only be
initiated by the Key Management Controller (KMC) operator.
