Motorola HF850 用户指南

Note: To use the functions described below, a Bluetooth

®

 link 

must be established between the car kit and your phone. 
Most phones automatically activate a Bluetooth connection 
when you place a call.

From the car kit to your phone: 
During a call, press and hold the Voice Dial button for more 
than 3 seconds. (Most phones prompt you to accept the 
transfer before completing the transfer.)

From your phone to the car kit: 
During a call, press and release the Multi-function button. 
(Some phones require you to press the Multi-function button 
twice. See the user’s guide for your phone for more 
information.)

To mute the microphone during a call. Press the car kit’s mute 
button. The Mute button will flash, and the other party will not 
be able to hear you.

To un-mute the call. Press the mute button again. 

If you receive a call while you already have a call in progress, 
you can end the current call or place it on hold while you 
answer the second call.
