malfunction. Do not use it on a soft surface such as a bed which might block ventilation slots.
• Do not place the videophone in direct sunlight. Do not point any external cameras directly at
the sun as this is likely to cause serious damage to the unit.
• The videophone will not function in the event of a power cut. It should not be relied upon as
the only means of contacting the emergency services.

Connection to the Power Supply
• Never overload power sockets.
• In order to remove power from this product, you must disconnect the power plug from the
power outlet. In order to safely achieve this action, the product must be installed close to the
power outlet and be positioned in such a way that user access to the power plug and socket
connection is not restricted.
• The product must only be used with the provided power supply. This power supply has been
extensively tested for use with the product, use of an alternative power unit may invalidate

CHAPTER 1 Introduction & Getting Started
This guide describes all the features of the mm146 and mm156 videophones and is
written both for administrators who are responsible for installing and configuring the
videophone and those who use it on a day-to-day basis.

4
About the mm146 and mm156 IP videophones
The mm146 and 156 IP videophones offer a major advance in video over broadband
and corporate IP networks. Designed specifically for non-QoS IP connections, this
attractive system is as easy to use as a telephone, but offers a wide range of
capabilities.
With the mm146 videophone you can:
1. Make toll-free videophone calls over the Internet.
2. Make group conferencing video calls using an external camera and TV.
3. Make multipoint conference calls using an external MCU.
4. Make calls to or audio conference ISDN videophones, regular phones and
mobiles using an external gateway.
With the mm156 you can additionally:
1. Make calls to or audio conference regular phones and mobiles over a regular
telephone line.
2. Make video calls over a regular telephone line
Unique technology
mm146 and mm156 videophones offer a range of unique features that improve the
user and administrator experience
Motion Media’s Packet Buddy protocol
1. Intelligently adapts to the available bandwidth over the Internet,
2. Recovers lost packets
3. Synchronises video and audio to provide excellent lip-sync.
Simplified installation
1. The IP videophones support DHCP and PPPoE protocols, allowing automatic
configuration of the core IP information.
2. The Packet Buddy Protocol uses a single UDP port to make a video call
instead of the 6+ ports used by an H323 device. This allows outgoing calls to
be made with little or no firewall configuration.
Reduced infrastructure costs
1. When first using mm146 and 156 videophones no dedicated video infrastruc-
ture (e.g. H.323 aware firewalls, gatekeepers, QoS Internet services, etc.) is

5
Introduction & Getting Started
required. This means you can experience the benefits of video without an
extensive and costly implementation phase.
2. Moving forward, mm146 and mm156 videophones also support the H.323
protocol, so can adapt to future infrastructure changes, and interoperate with
equipment from other vendors.
Enhanced video calls
A range of features give the user greater flexibility when in a call. These include:
1. Full-duplex Acoustic Echo Canceller for pause-free hands-free audio confer-
ences with no clipping.
2. Digital zoom
3. Image control (faster/sharper)
4. Local and remote audio and video source selection in call
5. Brightness control
6. Adjustable PiP
7. Freeze frame option
8. PIN authentication for security
Improved ease of use
1. Video and audio calls from one phone (mm156)
2. Fallback to PSTN (mm156)
3. Central phonebook facility
4. Built-in 10/100 hub allowing a PC to share your videophone connection
5. Physical camera cover for complete privacy

6
Getting Started
Requirements for the IP Videophone

Introduction & Getting Started
“Waking” the Videophone
If your videophone remains unused for approximately 20 minutes, it will go into
“sleep” mode and the screen appears blank.
To “wake” the videophone:
• Lift and replace the handset, or
• Press the start button, or
• Press the menu button, or
• Press the button, or
• Press the round arrow center button.
Getting the Best from your Videophone
There are a few steps you can take when setting up the videophone to ensure that you
get the best results.
Focusing the Camera
You can focus the built-in camera on your videophone to ensure that the video image
you send is crisp and clear.
To focus the camera:
1. Press the menu button to display the Setup Menu options.
2. Press the number 3key to view the Camera Video Setup options.
3. Press the number 1key to view the built-in camera preview. You should see
yourself on the screen.
4. Slowly twist the outer ring of the camera either way to bring the image into
sharp focus. Usually only a small adjustment is required.
Lighting
As with conventional photography, correct lighting is vital to achieving the best
results from your videophone.
Make sure your face is well lit, preferably from the front, and avoid having lights
behind you that might shine into the camera lens.

10
Movement
Too much movement tends to slow down the frame rate of the video, resulting in a
distorted picture. Avoid having a lot of movement in the background – for example,
do not sit with your back to a corridor – and try not to move around excessively. This
does not mean you have to sit completely still: just move naturally, but be aware that
if you make rapid movements, the person you are calling may see a distorted picture.
You can control the frame rate of the video you are sending, to adjust the balance
between smoothness and clarity. See Images on page 33, for more information. If
movement is important, set the Video Mode to Motion; if clarity is important, set the
Video Mode to Detail.
Sound
Where possible, it is better to choose a quiet environment than a noisy one. In very
noisy situations you will find the handset more effective than handsfree.
When using handsfree, remember that the built-in microphone is at the front right-
hand corner of the videophone. Don’t cover this with your hand, or tap on the
videophone case.
You should avoid picking up or moving the videophone during a call.

11
CHAPTER 2 Setting up the videophone

16
Setting the Phone Book Mode
There are two possible modes for the videophone.
•Master
•Slave
The videophone is supplied in Slave mode by default. If you have multiple units
within a LAN, you need to configure 1 unit in your network to be a Master unit. The
Master unit can then be configured with entries in the Phone Book. See “Setting up
the Phone Book” on page 14.
The Slave units within the same network can then be updated with Phone Book
entries contained in the Master unit. In this way, multiple Slave units on your LAN
can easily be updated with the Phone Book from a single Master unit.
To set the Mode of your videophone to Master:
1. Press the menu button, then press the number 1key to display the Phone
Book options.
2. Press the number 2key to highlight the Mode field.
