Note
"ERASED" appears on the transceiver main display if no SCM is installed in the transceiver, or if the SCM is disabled, or if no

Transceiver's Behavior upon Receipt of the Encrypted Communication Data
Upon receipt of the encrypted communication data, the transceiver behaves as follows according to the Encryption status
(enabled or disabled) and the configuration for Encryption Type.
If Encryption Is Enabled:
Regardless of the configuration for Encryption Type, the received audio sounds from the speaker according to the audio
control conditions and the configuration in the Multi-key List.
 Bit scramble encryption type
The transceiver's behavior varies as follows depending on whether 0 is configured for only one Key ID, or for more than
one Key ID in the Multi-key List.
• If 0 is configured for only one Key ID in the Multi-key List:
The transceiver searches the encryption key data configured for the transceiver. If the Key ID included in the
encryption key data, which was used for encryption of the received communication data, matches the Key ID
included in the encryption key data which is configured for the transceiver, the transceiver can use the encryption
key data to decrypt the data. If the data is properly decrypted, the received audio sounds from the speaker. If the
data is decrypted incorrectly, the received audio sounds incompletely from the speaker. The transceiver mutes the
speaker if the Key IDs do not match.
