To install the FDHF cartridge
To install the FDHF cartridge in an M3904 Phase III set, perform the
following steps:
1 Check the label on the back of your set to make sure that it is an M3904
Phase III set (NTMN34GA). If your set is an NTMN34GA, go to Step 2.
If your set is not an NTMN34GA, it is not FDHF-compatible. Please
contact your system administrator to obtain the correct set.

how to install the ACM, refer to “Accessory Connection Module
