General Information

The M155 DECT Messenger is a sophisticated cordless messaging
device for use in professional healthcare and hospitality environments.
The small device is easy to carry and provides the mobile user the
optimum in mobility, accessibility, flexibility and comfort.

Besides a message device the M155 also offers the mobile user
speakerphone communication and it acts as a personal alarm device.

The M155 is compatible with both traditional DECT and IP DECT
systems.

Feature overview

You can use the features of the NEC M155 to perform the following
tasks:

Send and receive messages
Set up and receive incoming speakerphone calls
personal alarm device (either by sending an SOS alarm message

or setting up an SOS loudspeaking call)

automatic update of the time and date settings when switching on

the M155

Notice to the user

The M155 DECT Messenger described in this manual should only be
used in combination with DECT systems delivered by NEC. To take
advantage of all features described in this manual the country specific
and network provider specific features should match the features of the
NEC system.

Please also use the other documentation supplied with the various parts
of your telephone system.

Cleaning your M155

You can clean the M155 with a dry cloth or a soft, lightly moistened
cloth. Never use chemicals, detergents, cleaning materials or solvents
such as alcohol or benzine.

Important safety information

8

Important safety information

Only use this product in countries where the relevant authorities have
authorised its operation.

Sensitive Electronic Equipment

Any radio-based equipment can potentially cause interference with
other equipment and can be interfered from other equipment. This also
applies for DECT equipment. However, due to the very low
transmission power level, interferences are unlikely. Research proves
that operational DECT devices normally don't influence electronic
equipment. However some precautions must be taken into account for
sensitive electronic equipment e.g. sensitive laboratory equipment.
When DECT devices operate in very close range to sensitive electronic
equipment, incidental influence can appear. You are advised not to
place the DECT device on or close (less then 10 cm) to this kind of
equipment, even in stand-by mode.

Charging the battery

This product uses a rechargeable (non-replaceble) Li-Polymer battery
(3.7V, 400mAh).

Charge the battery of the M155 only in combination with the M155
Desktop Charger and the attached Ktec KSLFB0500035W1UV-1
adapter that comes with the product.

Do not charge the battery by any other means.

The AC/DC adapter comes with 4 changeble mains plugs. Select the
appropriate mains plug for your country.

Plug the AC/DC adaptor in a wall outlet socket near the equipment for
easy access/removal of the AC/DC adaptor.

Safety precautions

Please observe the following notes on safety when setting up,
connecting and using the handset:

Do not open the M155 or the charger; this could expose you to high

voltages. Have all repairs carried out by authorized service
personnel.

Important safety information

9

Connect to approved accessories only.
Do not allow the M155 or the charger to come into contact with

water or chemicals.

Only use the AC adapter supplied.
Do not use AC adapters which are visibly damaged (cracked or

broken housing).

Do not use the handsets in vehicles or in hazardous locations.
This product contains magnetic material. Be aware that small

metallic objects may stick for example to the loudspeaker. This may
deteriorate the audio quality and can be harmful.

Warning:

Never touch the charger contacts with conductive
objects such as keys, paper clips, rings or bracelets.

Usage

Like all other cordless telephones, the M155 uses radio signals which
do not guarantee a connection set-up under all circumstances.
Generally, you should therefore not rely exclusively on cordless
telephones when making indispensable calls (e.g. medical
emergencies).

Product disposal information

Product disposal information

For countries in the European Union

The symbol depicted here has been affixed to your
product in order to inform you that electrical and
electronic products should not be disposed of as
municipal waste.

Electrical and electronic products including the cables,
plugs and accessories should be disposed of separately

in order to allow proper treatment, recovery and
recycling. These products should be taken to a designated facility
where the best available treatment, recovery and recycling techniques
are available. Separate disposal has significant advantages: valuable
materials can be re-used and it prevents the dispersion of unwanted
substances into the municipal waste stream. This contributes to the
protection of human health and the environment. Please be informed
that a fine may be imposed for illegal disposal of electrical and
electronic products via the general municipal waste stream.

To facilitate separate disposal and environmentally sound recycling
arrangements have been made for local collection and recycling. If you
need to dispose of your electrical and electronic products, please refer
to your supplier or the contractual agreements that your company made
when these products were acquired.

At www.nec-unified.com/weee you can find information about separate
disposal and environmentally sound recycling.

For countries outside the European Union

Disposal of electrical and electronic products in countries outside the
European Union should be done in line with the local regulations. If no
arrangement has been made with NEC Unified Solutions or your
supplier, please contact the local authorities for further information.

Battery information

Defect or exhausted batteries should never be disposed of as municipal
waste. Return old batteries to the battery supplier, a licensed battery
dealer or a designated collection facility. Do not incinerate batteries.

Product disposal information

17

This product uses a non-replaceble Li-Polymer battery.

The battery of the M155 should never be removed by the customer.
Return old M155s to the supplier, a licensed dealer or a designated
collection facility.

Getting started

18

Getting started

This section describes the tasks you must complete before you use
your M155 DECT Messenger.

Location of the M155 and the charger

Do not place the M155 or the charger near:

water, moisture or damp areas;
heat sources, direct sunlight or inadequately ventilated areas;
devices that produce strong magnetic fields, electrical devices,

fluorescent lamps, computers, radios, television sets, fax machines
and telephone terminals;

areas where the equipment may be covered, penetrated by fluids

and where its ventilation is impaired;

areas where there is excessive dust, and areas subject to vibration,

shock or extreme temperature fluctuations;

within reach of small children.

Installing the charger and charging the M155

To install the charger, perform the following steps:

1. Place the charger on a flat, even surface.

2. Select the appropriate mains plug from the set of four supplied with

the charger/AC adapter and click the mains plug in place on the AC
adapter.

3. Connect the AC adapter to an electrical outlet.

4. Place the M155 on the charger (note that LED on the charger lights

up) – See Figure 1: M155 in charger.

Attention:

A switched off M155 automatically switches on

when placed on the charger.

When a completely discharged M155 is put on the

desktop charger, it can take up to 5 minutes before
the display is lit.

Getting started

19

Charging guidelines

Observe the following guidelines when you charge the M155:

Charge the battery for at least 6 hours before you use the M155 for

the first time.

The battery attains maximum power output only after several

charging and discharging cycles.

Do not leave the M155 connected to the charger for more than a

month without using it.

You can charge and discharge the battery thousands of times.

Under normal conditions the battery life time exceeds the life time
of the M155. If eventually the operating time (talk and standby time)
becomes significantly shorter than usual, you’ll need to replace the
complete M155.

Charging and operating times

A discharged battery requires no more than 8 hours to completely
recharge. A completely charged battery provides the M155 set with up
to 8 hours of operating time1 and 80 hours of standby time.

Charge display

The battery charge status appears on the display screen. When the
battery is nearly discharged, the battery symbol flashes and a warning
tone sounds. If you are on a call, approximately 3 to 5 minutes of talk
time exists before the M155 switches off. If you are not on a call and the
M155 is not in the charging station, the message Battery low appears
on the display.

The following table shows the battery charge status icons:
