Applying labels to the base cover

The new base cover FRU is shipped with a kit containing labels of several kinds.

If the Windows Authetication label (COA) [1] is attached to a part that is replaced, return the old part with the label attached to the customer, or provide a letter to the customer stating what the label was originally on the system and what the label part number, serial number, and product key were.

When you replace the base cover, apply the following labels:

[4] Battery word label [19] Serial number label
[18] FCC label [20] Homologation label

Following labels need to be peeled off from the old base cover, and need to be put on the new base cover.

[2] SIM label
[12] Brazil wireless card label
[3] China Telecom label
[13] SIRIM label or Indonesia label
[5] Onboard LAN MAC address label or Ethernet label [14] China 3G Logo wireless WAN label
[6] IMEI label [15] SIM ICCID label
[7] Brazil Anatel Bluetooth label
[16] Taiwan wireless WAN label
[8] China 3G wireless WAN label
[17] Non Encryption label or Indonesia rating label
[9] Israel label [21] Product label
[10] Brazil wireless WAN label
[22] Wireless label for special bid
[11] China wireless WAN label
[23] Asset tag

For some models, you need to apply two FCC labels. Check the old base cover; if it has two FCC labels, apply both to the new base cover.

For the location of each label, refer to the following figure:
