Operating Parameters

The receive audio level is attenuated during the FDHF mode while both you
and the party you are speaking with are conversing; therefore, you may notice
fluctuations in the receive volume during a FDHF call.
During a call, the FDHF cartridge can be removed or inserted intothe ACM
without interrupting the established call. If the FDHF cartridge is removed,
half-duplex operation is restored.
Check that your telephone is an M3904 Release III set (NTMN34GA) by
looking at the label on the back. If it is, please continue to step 2. If it is not,
the FDHF cartridge is not compatible with your telephone. Please contact you
network administrator for more information.
Insert the FDHF cartridge into the ACM. The latch should be at the top.
Plug the wall transformer into an electrical outlet (use only the transformer
designed for your ACM accessories). The following transformers are
approved for use with the FDHF cartridge:
• 110V wall transformer (NTMN80AA)
• 220V wall transformer (NTMN80BA)
• EU 230V wall transformer (NTHC08AA)
• UK 230V wall transformer (NTHC09AA)
Disconnect the telephone line cord from the telephone wall jack (see figure
below)
Connect the Adapter plug, attached to your transformer, to the telephone wall
jack.
Connect the telephone line cord to the wall transformer adapter jack
Verify that the FDFH cartridge is working properly. The cartridge is operating
properly when the red LED on the cartridge is flashing and when 18
segments are displayed on the volume bar during handsfree volume
adjustment. Half-duplex displays only 12 segments
