4.4 POISONING DANGER
• Keep batteries away from small children
4.5 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 unit OFF when on board an aircraft when instructed to do so. Any use of the unit must be in accordance
with airline regulations or crew instructions.
• Turn your unit 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. Unau-
thorised antennas could also damage the radio.
4.6 NOTES
• Do not touch the antenna while transmitting, it could affect the range.
• Remove the battery 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 recycling of electrical and electronic equipments. The symbol on the product, user
guide and/or box indicate this.
Some of the product materials can be re-used if you bring them to a recycling point. By re-using some parts or raw
materials from used products you make an important contribution to the protection of the environment.
Please contact your local authorities in case you need more information on the collection points in your area.
7 USING A PMR DEVICE
To communicate between PMR devices they need to be set all on the same channel and within receiving range (up to
max. 3 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.
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. To reply, just press the button and speak into the microphone.
PTT
If 2 or more users press the - button 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 - button) when the channel is free .
