Motorola HF820 用户手册

• Phones that support only the Headset 

profile can only recognize functions 
associated with a short press of the

call button can initiate a voice dial or 
redial the last dialed number, 
depending on the phone’s settings.

• Your phone and service plan must 

support 3-way calling and call waiting 
to use the functions associated with 
these features.
