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.

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. 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 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 CTCSS/DCS code (see chapter “13.7 CTCSS (Continious Tone Coded Squelch System) / DCS (Digital Coded Squelch)”) and within receiving range (up to max. 8 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 ⑪.

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 ⑪ 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.

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.

13.7 CTCSS (Continious Tone Coded Squelch System) / DCS (Digital Coded Squelch)

License free PMR radio's operating on the 446 MHz frequency band, like the Twintalker 4810 PMR, have 8 available radio channels. If there are many PMR users in your neighborhood, there is a chance that some of these users are operating on the same radio channel.

To prevent that you receive signals from other users, sub-channels have been integrated.

Two PMR radio's will only be able to communicate with each other when they are operating on the same radio channel and when they have selected exactly the same sub-channel.

There are two kind of sub-channels :

• Continuous Tone Coded Squelch System (CTCSS)
  • Digital Coded Squelch (DCS)

When using CTCSS, a low frequency tone (between 67 and 250 Hz) will be transmitted along with the voice signal. There are 38 available tones to choose from. You are free to choose one of these 38 available tones. Due to filtering, these tones will generally not be audible so they will not disturb the communication.

DCS is similar to CTCSS, but instead of sending a continuous tone of a selected frequency, a digital data transmission is added to the radio signal. This Digital Code is transmitted at a really low rate, around 134 bits per second (the code is 23 bits long). Only the PMR's of the latest generation will support DCS. There are 83 available DCS codes that can be used.

Since earlier models will only support CTCSS it will be better to use DCS to prevent that other users will be audible during your PMR conversations.

13.7.1 CTCSS

• Press the ➕ -button ⑤ twice : "CTCSS" and the current CTCSS code flashes on the display.
• Press the -button or the ⑨ button to change to another code.
• Press the PTT-button ⑪ to confirm and return to stand-by mode.

13.7.2 DCS

• Press the ➤ -button ⑤ three times : "DCS" and the current DCS code flashes on the display.
• Press the -button or the ⑨ button to change to another code.
• Press the PTT-button ⑪ to confirm and return to stand-by mode.

To disable CTCSS or DCS, select code "00" for CTCSS or for DCS in the menu. When the entry is confirmed, "OF" will be displayed.

13.8 Monitor

You can use the monitor feature to check for weaker signals in the current channel.

• Press the -button and -button simultaneously to activate channel monitoring.
• Press the -button to stop5channel monitoring.

During channel monitoring the receiver circuit in the PMR will not listen to CTCSS or DCS codes.

13.9 VOX Selection

The PMR is capable of voice activated (VOX) transmission. In VOX mode, the radio will transmit a signal when it is activated by your voice or other sound around you. VOX operation is not recommended if you plan to use your radio in a noisy or windy environment.

VOX mode will be overridden when you press the PTT - button ⑪.

19 Warranty

19.1 Warranty period

The devices have a 36-month warranty period. The warranty period starts on the day the new unit is purchased. There is no warranty on standard or rechargeable batteries (AA/AAA type). Consumables or defects causing a negligible effect on operation or value of the equipment are not covered. The warranty has to be proven by presentation of the original or copy of the purchase receipt, on which the date of purchase and the unit-model are indicated.

19.2 Warranty handling

A faulty unit needs to be returned to an authorized service centre including a valid purchase note and a filled in service card. If the unit develops a fault during the warranty period, the service centre will repair any defects caused by material or manufacturing faults free of charge, by either repairing or exchanging the faulty units or parts of the faulty units. In case of replacement, colour and model can be different from the original purchased unit.

The initial purchase date shall determine the start of the warranty period. The warranty period is not extended if the unit is exchanged or repaired by the service centre.

19.3 Warranty exclusions

Damage or defects caused by incorrect treatment or operation and damage resulting from use of non-original parts or accessories are not covered by the warranty.

The warranty does not cover damage caused by outside factors, such as lightning, water and fire, nor any damage caused during transportation. No warranty can be claimed if the serial number on the units has been changed, removed or rendered illegible. Any warranty claims will be invalid if the unit has been repaired, altered or modified by the buyer.

1. Skinite kopču za pojas (pogledajte poglavlje "9.1 Postavljanje/Skidanje kopče za pojas").
2. Podignite poklopac baterije laganim guranjem kopče poklopca (C) pomoću vašeg nokta.
3. Umetnite NiMh baterije. Pazite da su polariteti NiMh baterija ispravno okrenuti.
4. Zatvorite vratašca za baterije.
5. Vratite kopču za remen.

10 Punjenje baterija

Kad su baterije instalirane, stolni punjač omogućava praktično punjenje.

Za potpuno punjenje baterija treba oko 8 do 10 sati.

Baterija je puna

Baterija je puna 2/3

Baterija je puna 1/3

Baterija je prazna

Kada je razina napunjenosti baterije niska, simbol baterije će treptati i oglasava se zvučni signal radi signaliziranja da je baterije potrebno zamijeniti ili napuniti.

Nikad ne punite baterije koji nisu punjive, primjerice poput alkalnih baterija.

13.3 Podešavanje glasnoće zvučnika

• Pritisnite tipku u moću Spreman da biste povećali glasnoću zvučnika. Razina glasnoće prikazana je na zaslonu.
• Pritisnite tipku ▼ ⑥ da biste smanjili glasnoću zvučnika.

13.4 Primanje signala

Uređaj je neprekidno u modu primanja kada je UKLJUČEN, a ne obavlja prijenos.

Kako bi drugi mogli primiti vaš prijenos i oni moraju biti na istom kanalu i imati podešen isti CTCSS ili DCS kod. (Pogledajte poglavlja “13.6 Promjena kanala” i “13.7 CTCSS (Continuous Tone Coded Squelch System - Sustav potiskivanja signala kontinuiranim tonom) / DCS (Digital Coded Squelch - Digitalno kodirano potiskivanje signala)”) Moguće je koristiti ili CTCSS ili DCS kod, ali nikada oba istovremeno.

13.5 Prijenos signala

• Pritisnite i držite tipku PTT ⑪ da biste obavili prijenos. Na zaslonu je prikazana oznaka TX.
• Držite uređaj u okomitom položaju tako da mikrofon bude 10 cm od usta i govorite u mikrofon.
• Otpustite tipku PTT ⑪ kada želite prekinuti prijenos.

Kako biste provjerili aktivnost kanala, koristite funkciju nadzora (pogledajte poglavlje “13.8 Provjeravanje”).

• Continuous Tone Coded Squelch System (CTCSS)
  • Digital Coded Squelch (DCS)

Pri korištenju CTCSS, zajedno s glasovnim signalom će se odašiljati niskofrekventni ton (između 67 i 250 Hz). Moguće je odabrati bilo koji između 38 ponuđenih tonova. Slobodno možete odabrati jedan od tih 38 dostupnih tonova. Zbog filtriranja te tonove općenito nije moguće čuti, stoga neće ometati komunikaciju.

DCS je sličan CTCSS-u, ali umjesto slanja kontinuiranog tona odabrane frekvencije, radio signalu se dodaje prijenos digitalnih podataka. Digitalni kod se odašilje pri niskoj brzini od oko 134 bita u sekundi (kod je dugačak 23 bita). DCS će podržavati samo PMR uređaji najnovije generacije. Postoji 83 dostupna DCS koda za korištenje. S obzirom da raniji modeli podržavaju samo CTCSS, bolje je koristiti DCS za sprječavanja oglašavanja ostalih korisnika tokom vaših PMR razgovora.

13.7.1 CTCSS

• Dvaput pritisnite tipku : Na zaslonu će treptati "CTCSS" i trenutni CTCSS kod.
• Pritisnite tipku ili tipku ⁹ da biste promijenili na drugi kod.
• Pritisnite tipku PTT ⑪ za potvrđivanje i povratak u mod Spreman.

13.7.2 DCS

• Triput pritisnite tipku : Na zaslonu će treptati "DCS" i trenutni DCS kod.
• Pritisnite tipku ili tipku ⑨ da biste promijenili na drugi kod.
• Pritisnite tipku PTT ⑪ za potvrđivanje i povratak u mod Spreman.

• Pritisnite tipku sedamputa: Na zaslonu trepće "SC" i "DCS 00" za odabrani radio kanal.
  • Za pokretanje DCS pretraživanja pritisnite tipku ili ▲ ⑨ tipku ▼ ⑥ .

Kad se jednom uspostavi prijenos na kanalu, DCS kod (ako se koristi) će biti automatski detektiran i prikazan.
