Motorola I275 ユーザーガイド

If you use a headset or similar device with your 
phone, you can set your phone to send incoming 
sound to the headset only, or to the headset and 
the speaker at the same time:

1 From the main menu, select Settings > 

Advanced > Headset/Spkr.

2 Select HdsetOnly to send incoming sound to 

the headset only. -or-

Select Hdset&Spkr to send incoming sound to 
the headset and ring tones to the speaker. 

1 Lift the audio jack cover.
2 Insert the headset connector firmly into the 

audio jack. You may have to rotate the headset 
connector until it fits securely into the audio jack.

If you are using a headset or other accessory with 
a remote PTT button, you can use the remote PTT 
button for phone calls, Private calls, group calls, 
and SDG calls*.

For phone calls, use the remote PTT button to 
answer calls, switch between calls, and end calls. 
Hold the remote PTT button for less than 2 
seconds to answer calls and switch between calls. 
Hold the remote PTT button for more than 2 
seconds to end calls.

For Private calls, group calls, and SDG calls*, use 
the remote PTT button as you would the PTT 
button on your phone.

Note: When using a headset, the PTT button on 

your phone works the same way as when 
you are not using a headset. Sounds 
associated with Private calls, group calls, 
and SDG calls* are heard through the 
headset.
