Handsfree Microphone (HFM–7B)
The Handsfree Microphone can usually be installed on the driver’s sun visor or
A–pillar. The main idea is to get the microphone as close to the driver’s mouth
as possible, and to attach the microphone to a surface that is mechanically
quiet. The microphone connects to the bottom of the Compact Handsfree Unit
(PHF–1P) to the microphone jack. The microphone should be mounted at
least 3 ft away from the Compact Handsfree Unit (PHF–1P) to avoid
acoustic feedback.
Compact Handsfree Car Kit Operation
Once the handportable is placed in the Mobile Holder (MBH–6) in a vehicle, you
may set the KEYPAD TONES, RINGING VOLUME, and the LIGHTS of the
phone differently from the setting selected for handportable use. The phone will
memorise these car settings and use them whenever the phone is placed in the
Mobile Holder (MBH–6).
Lights (Menu 4 1)
When the phone is connected to a car kit, desktop charger, or cigarette lighter
charger, the lights are on permanently when this setting is ON; when this setting
is OFF, the lights come on when you press a key or have an incoming call, and
go off 15 seconds later.
Ringing Volume (Menu 4 2)
Your hear each ringing level as you scroll throught the volume levels. When the
phone is connected to a handsfree desktop charger, handsfree car kit or
headset, the ringing volume can be set separately for those accessories with
this menu.
Keypad Tones (Menu 4 4)
You can select the volume level or turn off the sound the phone makes when
you press a key.
Note: The keypad tone volume is set separately for each accessory you use.
