Code Setting

Master Key code setting

The master key code is a password to allow the authorised operator access to the system
management settings for maintenance. It also forms the key onto which the encryption
algorithm is applied.
To prevent unauthorised tampering with the system code settings and possible damage to the unit
from incorrect code entry (see warning below), the master key code MUST be changed to your own
code prior to operation and the new code should be noted and securely stored.
To change the Master Key code, type the [AMS] command using a terminal program on a PC.
cmd>AMA_123456789012 [CR]
CMD>AMA OK
************
CMD>AMS_
Note : The master key code consists of 12 digits of numeric code (0 ~ 9). Default code: 123456789012
(Refer to: Control commands on page 24 for details.)
Warning!
The master key code MUST be kept in a secure place. Without a master key
code no code changes can be made.
If you made an entry error during the initial code setting, correct it under the Master Key code entry
screen before exiting. Once you exit from the master key code setting screen with an
incorrect/unknown code, neither you nor the factory will be able to change it!

User ID code Setting

The User ID code is a unique code set by you to identify your own ARD9900 for use with the digital
squelch mode.
To change the ID code, first type the [AMA] command to allow entry into the
Data management Menu:
************
cmd>AMA_
CMD>AMA OK
*****
CMD>AUI_ [CR]
Note : The user ID code consists of 5 digits of numeric code (0 ~ 9)
Default : 77777
(Refer to: Control command on page 24 for details.)

Air Key code Setting

The Air Key code is a string of encryption code information that is attached to the beginning
of the transmitted data packet.
To set the Air Key code, first type the [AMA] command to allow entry into the
Data management Menu:

cmd>AMA_
CMD>AMA OK
