Instruction manual

FEATURES AND SERVICES
— The set generates a tone burst over its speaker to indicate an incoming call.
— The parties may converse.
The called party can speak in a normal voice
toward the set. No other action by the called party is required.
— During the call, the called party can press the HFAI/Mic or MICROPHONE
button to mute the microphone temporarily and prevent the caller from
hearing. Pressing the button again turns the microphone on again.
— The HFAI/BIS user may press the SPEAKER (HFAI set) or the
SPEAKERPHONE (BIS set) button to end the call. If the calling party hangs
up first, this is not necessary.
● If only the AUTO ANS LED is on:
— The set generates a tone burst over its speaker to indicate an incoming call.
— The set’s speaker turns on and the set “answers” the call.
— Call setup is complete. However, the called party can hear, but not respond
to, the calling party. To respond, the user must lift the handset or press the
HFAI/Mic button on an HFAI set or press the MICROPHONE button on a BIS
set.
— The HFAI/BIS user may press the SPEAKER (HFAI set) or the
SPEAKERPHONE (BIS set) button to end the call. If the calling party hangs
up first, this is not necessary.
● If only the HFAI LED (or neither LED) is on:
— The HFAI feature is disabled. The call answering procedure is the same as
for a standard MERLIN System set.
If, during a HFAI call, the user decides to pick up the handset, the HFAI/Mic or HFAI LED will
turn off. On a HFAI set, the user is not permitted to revert to hands-free operation.
(Pressing the HFAI button while using the handset will simply disable the HFAI feature for
subsequent calls.) A BIS set user may transfer a call from the handset to the speakerphone
by pressing the SPEAKERPHONE button and hanging up.
Voice Terminals with Speakerphone or Headset Adjuncts
These sets do not have a HFAI button. To turn on the HFAI feature the user simply presses
the AUTO ANS button; the green status LED lights.
After HFAI is activated, operation is exactly the same as for the BIS set except that the
SPEAKERPHONE and MICROPHONE buttons and LEDs are on the HFU.
Note, that the 502B Headset Adapter is required for HFAI operation with a headset (as is
usually desired in ACD operation).
