VM9423
Hands Free Profile (HFP)
To use a phone wirelessly with this unit, it is necessary to first
establish a connection using Bluetooth wireless technology.
Connection is normally established using HFP (Hands Free
Profile), which gives you full control of functions available on
the telephone source. However, depending on your phone,
the connection may be made using HSP (Head Set Profile),
making some functions unavailable. This is a limitation of
your phone, not the VM9423.
Since there are a number of Bluetooth mobile phone
implementations available on the market, operations with
your Bluetooth mobile phone using this unit vary greatly.
Please refer to the instruction manual that came with your
Bluetooth mobile phone along with this manual while
operating your phone with this unit.
Pairing the Bluetooth System with
Your Mobile Phone and Head Unit
1. Press the button (8) to initiate the pairing process.
Keep the mobile phone within 2 meters of the head unit
when pairing. (To terminate the pairing process, press
the button again.)
2. Select the Bluetooth setup option on the mobile phone
to be paired (please refer to the phone’s instruction
manual to learn how to enter Bluetooth setup, turn
Bluetooth on/off, and perform pairing).
NOTE: Some phones require a “pass key” or pairing
code to connect. If your phone requires a pass key or
pairing code, you will need to enter this number in the
Pairing Code field under the Bluetooth SETUP menu. The
default pairing code for many phones is “0000”. The
default code for the VM9423 is “1234”. See “Bluetooth
Sub-menu Features” on page 10 for instructions on
entering the pairing code.
3. Select “VM9423” from the pairing list on the mobile
phone.
• If pairing is successful, the TFT will display the
paired mobile phone model number or name (as
specified in your phone’s Bluetooth Setup menu).
• If pairing fails, “Phone Pairing Fail” is displayed at
the bottom of the screen.
Reconnecting
Once the Bluetooth device has been paired, you can touch
the connect button to reconnect.
NOTE: You can only connect to a phone using the
buttons on the on-screen Phone interface.
Each time the button is pressed, the head unit will
automatically reconnect with the mobile phone once (only if
the mobile phone was previously paired with the head unit).
Managing Incoming Calls
When connected to a Bluetooth phone, the unit will mute
audio output, pause CD play, and change to the Bluetooth
screen when a call is received. An incoming phone number
will appear at the top of the screen. If the screen is closed,
the number will scroll across the LCD. If the incoming call has
no caller ID, the TFT or LCD will display “Restricted Number”.
Answering an Incoming Call
To answer the call, touch the button.
For best reception, speak loudly and clearly.
To end the conversation, press the button. The screen will
display the call duration for 3 seconds, and then return to the
previous mode.
Rejecting an Incoming Call
Touch the button to reject an incoming call. The call will
revert to your phone and can be answered directly or left for
voice mail.
Volume Control
To increase or decrease the volume level, turn the AUDIO
control (5) on the front panel or press the VOL+/ VOL-
buttons (15, 16) on the remote control.
Microphone Mute
To mute the microphone, touch the button. Touch again to
resume microphone functionality.
Making an Outgoing Call
NOTE: Press the button from the main Bluetooth
screen to automatically dial the last call received.
1. Touch the button to open the direct dial screen.
2. Use the 0-9, *, and # buttons to input the phone number.
• Touch the CLEAR button to clear the last digit.
• Touch the button to clear the entire number and
start over.
3. After entering the phone number, press the button to
dial the call. The direct dial screen will close once your
call is connected.
To end the conversation, press the button.
Call Transfer
While talking, to transfer audio from the head unit back to the
mobile phone, touch the button (7). The TFT will display
“Transfer”. You can only transfer a call after it has been
answered.
Menu List
The menu list appears on the left side of the screen and can
be accessed from other modes by touching the MENU button
on the right side of the screen.
NOTE: Not all phones allow access to missed, received
or dialed calls and some will not allow uploading of your
phone’s address book.
Missed Calls
The Missed Calls list retrieves the list of Missed numbers
from your phone. The last missed number is the first number
on the list. Touch the Missed Calls menu option to view the
list. To make a call from the Missed Calls list, touch the
number and then touch the button. The TFT will display
“Cannot get missed record” when the feature is not available.
