RA Product

Code Sticker

Note

This kit does not contain a replacement "RAxxx" Product Code label.

This code is used by Harris as reference should you return your radio

for service or request an advance exchange radio link.

Please contact Customer Service (see page 2) for a new RA product

code label for your modified radio. Provide the existing RA product

codes (each is unique) for all Aurora radios you will be modifying with

this procedure.

This procedure only applies to Aurora 2400 Model 3 (M3 or

higher) and Aurora 5800 Model 2 (M2 or higher).

This procedure requires the radio to be turned off. Before you

take the radio offline, temporarily redirect traffic or plan for a

service outage.

Customer Service will convert your existing Product Code number to

reflect the new configuration (now 10Base-T or T1/E1) and send the

new labels to you.

When you receive the new label, apply it to the back of the radio.
