Part Description

switch your phone to silent mode, vibration mode, or airplane
mode.
Volume Up/Down Keys Allows you to adjust the ringtone or media volume or adjust the
voice volume during a call.
Direct Wave Receiver
The phone is equipped with a “Direct Wave Receiver” which transmits sound by vibrating the display
area. You can call without needing to worry about where to place your phone although there is no
hole in the receiver. We recommend the following usage for better hearing.
Hold the Phone to Your Ear
Hold the receiver so that it covers your ear as much as possible and blocks out surrounding noise for
clearer sound. Adjust the position of the phone up, down, left or right to suit your hearing and the
surrounding environment.
Direct Wave Receiver Cautions
Do not put a sticker, sheet, etc. on the display. The other party’s voice may become hard to hear.
n
Make sure not to cover the mic with your finger etc. when you talk on the phone.
n
When an earphone (commercially available) is connected to the phone, sound is from the
earphone instead of the Direct Wave Receiver.
