Safety Information and WarningsInformation on Safe OperationRead This Information Before Using Your Radio.The operation of your radio in Your country is subject to conditions in the following license:Radio AntennaDo not use any radio that has a damaged antenna. If a damaged antenna comes in contact with the skin, a minor burn may result.Unauthorized antennas, modifications, or attachments could damage the radio and violate compliance.Do NOT change or modify the antenna.Do NOT hold the antenna when the radio is “IN USE.” Holding the antenna reduces range and may cause bodily harm.Safety and general use whilst in a vehicleCheck the State and Federal laws and regulations regarding the use of two way radios in the area where you drive,and always obey them.For Vehicles fitted with Air BagsDo not place your radio in the area over an air bag or in the air bag deployment area. Air bags inflate with great force.If a radio is placed in the air bag deployment area and the air bag inflates, the radio may be propelled with great force and causeserious injury to the occupants of the vehicle.BatteriesAll batteries can cause property damage and/or bodily injury such as burns if conductive material such as jewellery, keys, or beadedchains 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 withmetal objects.Do not replace or charge batteries in a potentially explosive atmosphere. Contact sparking may occur while installing orremoving batteries and cause an explosion.Potentially Explosive AtmospheresTurn your radio OFF when in any area with a potentially explosive atmosphere. Sparks in such areas could cause an explosion or fireresulting in injury or even death.NOTE: Areas with potentially explosive atmospheres are often, but not always clearly marked.They include fueling 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.Blasting Caps and AreasTo avoid possible interference with blasting operations, turn your radio OFF near electrical blasting caps or in a “blasting area” orin areas posted: “Turn off the two way radio.” Obey all signs and instructions.Transmit and Receive ProcedureYour two-way radio contains a transmitter and a receiver. To control your exposure and ensure compliance with the generalpopulation/uncontrolled environment exposure limits, always adhere to the following procedure:•Transmit no more than 50% of the time. To receive calls, release the PTT button.To transmit (talk), press the Push to Talk (PTT) button. Transmitting 50% of the time, or less, isimportant because the radio generates measurable RF energy exposure only when transmitting (interms of measuring standards compliance). Always hold the radio approximately 5cm in front ofyour mouth with the antenna pointing away from your head.Radio Operation and EME ExposureUnauthorized antennas, modifications, or attachments could damage the radio and violate Compliance.Do NOT hold the antenna when the radio is “IN USE.” Holding the antenna reduces the effective range.Do not use the radio if the antenna is damaged. If a damaged antenna makes contact with your skin,a minor burn can result. If you wear a radio on your body when transmitting, always fit the radio on thebelt clip (supplied). Always ensure the radio and it's antenna are at least 5cm from your body when transmitting.Electromagnetic Interference/Compatibility
Nearly every electronic device is susceptible to electromagnetic interference (EMI). To avoid thepossibility of electromagnetic interference and/or compatibility conflicts, turn off your radio in anylocation where posted notices instruct you to do so such as health care facilities.AircraftWhen instructed to do so, turn off your radio when onboard an aircraft. Any use of a radio mustbe in accordance with applicable regulations per airline crew instructions.Medical Devices – PacemakersThe Advanced Medical Technology Association recommends that a minimum separation of 6inches (15cm) be maintained between a handheld wireless radio and a pacemaker. Theserecommendations are consistent with the independent research by and recommendations ofthe U.S. Food and Drug Administration. People with pacemakers should:····ALWAYS keep the radio more than 15cm from their pacemaker when the radio is turned ON.Not carry the radio in the breast pocket.Use the ear opposite the pacemaker to minimise the potential for interference.Turn the radio OFF immediately if there is any reason to suspect that interference is taking place.Medical Devices --‐Hearing AidsSome radios may interfere with some hearing aids. In the event of such interference, you may want to consult your hearingaid manufacturer to discuss alternatives.Other Medical DevicesIf you use any other personal medical device, consult the manufacturer of your device to determine if it is adequatelyshielded from RF energy. Your physician may be able to assist you in obtaining this information.General warningsNever use your radio outdoors during a thunderstorm. Keep the radio out of reach of babies and young children.INSTALLATIONRemoving the belt clipPull the belt clip latch away from the unit.Installing the BatteriesFOR USE OF RECHARGEABLE BATTERIES:If your walkie talkie comes with a rechargeable battery pack or USB cable, dual USB adaptor and dual USB car charger.The fully charging time is about 12 hours.The adaptor and car charger will only charge the battery pack provided and not other types of rechargeable batteries.After placing batteries into correct positions, replace the battery cover.FOR USE OF NON RECHARGEABLE BATTERIES:123.Slide down the battery compartment cover..Insert 3 x AAA batteries (not included)..Position the batteries according to the polarity marking on the battery compartment. After placing batteries into correct positions,replace the battery cover.Low Battery Meter IndicatorThe radio can detect the low battery level when the battery voltage goes low. The battery icon will display the low battery status.
When battery voltage is low, the empty battery symbol will appear and continue to blink. The battery symbol will continuouslyblink until it totally drains the battery voltage where then you will have to replace the batteries.Transmitting RangeThe talk range will depend on your surroundings and environment it will be affected by obstructions such as hills or buildings.Don’t try to use two radio units which are less than 1.5m (5 feet) apart. Otherwise, you may experience interference.Talk range depends on the terrain. It will be affected by concrete structures, heavy foliage and by operating radiosindoors or in vehicles.Operating the unitTurning unit on/off:1-- Switching onPress and hold the MENU/PWR until you hear a beep sound.-- Switching off2Press and hold the MENU/PWR until you hear a beep sound.Adjusting the Volume:You have 8 preset volume levels. They are displayed on the LCD screen. To raise the volume press the up button (SCAN) andto decrease the volume, press the down button (MONI).Auto scan.Press & hold the UP button for 3 seconds to activate auto scan.Press Menu/PWR button to deactivate auto scan.Monitor (Zero squelch)Press & hold the DOWN button for 3 seconds to activate monitor.Press & hold the DOWN button for 3 seconds to deactivate monitor.Changing ChannelsYou have channels with the legal frequency at your disposal. To communicate with another device,you must both be on the samechannel.To change channels, once you have turned your unit on, you need to press the MENU/PWR once and use the up/down buttons
