If an Ear Microphone/Headset is attached to a GDC-400H, it can receive or release a call. It is
recommended to use a Headset meeting JIS C-6560 Specification. Press the button on the Ear
Microphone/Headset to receive an incoming call when ringing, and do the same action to release the call.
Making a call by using the Ear Microphone/Headset is supported, too; press the button once on the Ear
Microphone/Headset when in the idle state, then select a number to dial from the redial list and the make the
call by pressing the button.
Note:
Using a noise canceling or unidirectional Ear Microphone/Headset, with an impedance below 1 K
Ω
(usually
is 1-2.2K
Ω
) may cause abnormal operation (unit may self-answer without pressing the button when an
incoming call is received, and unit may hang-up unexpectedly while using the Ear Microphone/Headset).
