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 on 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.

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.

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. Unauthorized antennas could also damage the radio.

4.7 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 reusing 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 guaranteed. 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. To reply, just press the PTT-button ⑫ and speak into the microphone.

If 2 or more users press the PTT- button at the same time the receiver will receive only the stongest signal and the other signal(s) will be suppressed. Therefore you should only transmit a signal (press PTT- button when the channel is free.
