Making a phone call
With Bluetooth
®
enabled phones (cell phones or smartphones) that support the “HSP” or “HFP” Bluetooth
®
profile, you can use the unit for phone calls.
• HSP (Headset Profile):
This profile can be used to receive monaural sounds and establish two-way communication using the
microphone on the unit.
• HFP (Hands-Free Profile):
In addition to the HSP functions, this profile has the incoming and outgoing calls function.
(This unit does not have a function that allows you to make phone calls independently of a Bluetooth
®
enabled
phone.)
1
Connect the Bluetooth
®
device and the unit. (
2
Touch a touch sensor (L or R) on the earphone once to answer an incoming call.
• During an incoming call, ringtone will sound from the unit and the earphone LEDs will blink.
• (HFP only) To reject a phone call, touch and hold a touch sensor (L or R) for about 2 seconds.
3
Start talking.
• The earphone LEDs will repeatedly blink 2 times during a call.
• To mute the voice during a call, touch the touch sensor (R) twice.
(To cancel muting, touch the touch sensor (R) twice again while muting.)
• To switch the noise level of the other party during a call, touch the touch sensor (R) 3 times.
Voices will be easier to hear when you reduce the audio noise from the other party.
This function is effective in reducing the noise heard from continuous sources (ventilation fans, etc.) in the
vicinity of the other party.
• The volume can be adjusted during a phone call.

®
enabled phone.
• Depending on the Bluetooth
®
enabled phone, you may hear incoming and outgoing call ringtones of the phone from
the unit.
• You can have the Bluetooth
®
enabled phone make phone calls by using the microphone of the unit and an app of the
Bluetooth
®
enabled phone. (
