If an Ear Microphone/Headset is attached to a GDC-450H, 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.

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).
