Enable (1) an extension's ability to use the speakerphone.
Using the Adapter
● The HF-R adapter requires approximately 20 seconds to start up after first powering up the adapter.
The microphone's LED will remain off during this period. When the microphone is activated, the LED
will light (as long as the microphone switch on the adapter is enabled).
● The microphone's sound can be muted using the switch on the microphone.
● The microphone cable provides 6' of cable. The placement of the microphone unit can be anywhere
within this 6' distance. For the best voice quality, it is recommended that the microphone unit be
positioned with either the front or the side of the microphone facing the user. The back end (with the
line cord) should not be facing the user.
● If confirmation tones are enabled (service code 824), when a call is placed on a trunk, the user will hear
double confirmation tones as the keys are pressed. The call, however, will complete normally.
4-50 ◆ Section 4: Telephones and Optional Equipment
Plug the end of the mic cord which has the ferrite bead closest to it into the jack on the adapter. The
opposite end should then be connected to the microphone.
To avoid any hardware problems, when removing the adapter, first unplug the line cord, then
the power cord, then any other adapter cables.

If the microphone is placed to the right of the phone and the volume is set to the maximum,
when the user presses the CALL1 key, the ICM dial tone may modulate. Turning down the volume
or moving the microphone should clear this problem.
When confirmation tones are enabled or when placing a call on an outside trunk, the user will
hear double tones as the keys are pressed.
