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
16
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,

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 time1and 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.
