1 Introduction
Thank you for purchasing the MTD90. It’s a long range, low powered radio
communication device with a range of maximum 10 Km. It has no running costs other than the
minimal cost of re-charging the batteries. The MTD90 operates on 8 channels.
2 Intended purpose
It can be used for recreational purposes. For example: to keep in contact during travelling with
2 or more cars and cycling. Widely used for building sites and to keep in contact with your
children when they are playing outside, etc...
3 CE Mark
The CE symbol on the unit, user guide and giftbox indicates that the unit complies with the
essential requirements of the R&TTE directive 1995/5/EC.
4 Safety instructions
4.1 General
Please read carefully through the following information concerning safety and proper
use. Make yourself familiar with all functions of the device. Keep this manual in a safe
place for future use.
4.2 Burning injuries
• If the cover of the antenna is damaged, do not touch because when an antenna
comes in contact with the skin, a minor burn may result when transmitting.
• Batteries can cause property damage such as burns if conductive material such as
jewellery, keys or beaded chains touches exposed terminals. The material may
complete an electrical circuit (short circuit) and become quite hot. Exercise care in
handling any charged battery, particularly when placing it inside a pocket, purse or
other container with metal objects.
4.3 Injuries
• Do not place your device in the area over an air bag or in the air bag deployment
area. Air bags inflate with great force. If a PMR is placed in the bag deployment
area and the air bag inflates, the communicator may be propelled with great force
and cause serious injury to the occupants of the vehicle.
• Keep the PMR at least 15 centimetres away from a pacemaker.
• Turn your PMR OFF as soon as interference is taking place with medical
equipment.
4.4 Danger of explosion
• Do not replace batteries in a potentially explosive atmosphere. Contact sparking
may occur while installing or removing batteries and cause an explosion.
• Turn your PMR off when in any area with a potentially explosive atmosphere.
Sparks in such areas could cause an explosion or fire resulting in bodily injury or
even death.
• Never throw batteries in fire as they may explode.

4.5 Poisoning danger
• Keep batteries away from small children.
4.6 Legal
• In some countries it is prohibited to use your PMR while driving a vehicle. In this
case leave the road before using the device.
• Turn your PMR OFF when on board an aircraft when instructed to do so. Any use
of the PMR must be in accordance with airline regulations or crew instructions.
• Turn your PMR OFF in any facilities where posted notices instruct you to do so.
Hospitals or health care facilities may be using equipment that is sensitive to
external RF energy.
• Replacing or modifying the antenna may affect the PMR radio specifications and
violate the CE regulations. Unauthorised antennas could also damage the radio.
4.7 Notes
• Do not touch the antenna while transmitting, it could affect the range.
• Remove the batteries if the device is not going to be used for a long period.
5 Cleaning and maintenance
• To clean the unit, wipe with a soft cloth dampened with water. Don’t use a cleaner or
solvents on the unit; they can damage the case and leak inside, causing permanent
damage.
• Battery contacts may be wiped with a dry lint-free cloth.
• If the unit gets wet, turn it off and remove the batteries immediately. Dry the battery
compartment with a soft cloth to minimize potential water damage. Leave the cover off
the battery compartment overnight or until completely dry. Do not use the unit until
completely dry.
6 Disposal of the device (environment)
At the end of the product lifecycle, you should not throw this product into the
normal household garbage but bring the product to a collection point for the

Areas with potentially explosive atmospheres are often, but not always,
clearly marked. They include fuelling areas such as below deck on
boats, fuel or chemical transfer or storage facilities; areas where the air
contains chemicals or particles, such as grain, dust or metal powders;
and any other area where you would normally be advised to turn off
your vehicle engine.

7 Using a PMR device
To communicate between PMR devices they need to be set all on the same channel and
CTCSS / DCS code (see chapter “13.7 CTCSS (Continious Tone Coded Squelch System) /
DCS (Digital Coded Squelch)” and within receiving range (up to max. 10 km in open field).
Since these devices use free frequency bands (channels), all devices in operation share these
channels(total 8 channels). Therefore, privacy is not garanteed. Anybody with a PMR set to
your channel can overhear the conversation. If you want to communicate (transmitting a voice
signal) you need to press the PTT-button 12 .
Once this button pressed, the device will go into transmit mode and you can speak into the
microphone. All other PMR devices in range , on the same channel and in standby mode (not
transmitting) will hear your message. You need to wait until the other party stops transmitting
before you can reply to the message. At the end of each transmission the unit will send a beep
if the Roger Beep is enable (see chapter “13.12 Roger Beep On/Off” ). To reply, just press the
PTT-button 12 and speak into the microphone.

8 Included in the package
• 2 x MTD90
• 2 x Desktop Charger
• 2 x Power adapter
• 8 x AAA NiMh batteries
• User guide
If 2 or more users press the at the same time the receiver
will receive only the stongest signal and the other signal(s) will be
supressed. Therefore you should only transmit a signal
(press PTT-button 12 when the channel is free.
PTT-button 12
The range of radio waves is strongly affected by obstacles such as
buildings, concrete/metal structures, the unevenness of the landscape,
woodland, plants, … This implies that the range between two or more
PMR's may in some extreme cases be restricted to a maximum of a few
tens of meters. You will soon notice that PMR works best when there is
a minimum of obstacles between users.
