RD866 Walkie Talkie user manual

Operating Instructions Handheld Walkie talkie Safety Information and Warnings Information on Safe Operation Read This Information Before Using Your Radio. The operation of your radio in Your country is subject to conditions in the following license:

Radio Antenna Do 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 vehicle Check 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 Bags Do 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 Cause serious injury to the occupants of the vehicle. Batteries All batteries can cause property damage and/or bodily injury 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. Do not replace or charge batteries in a potentially explosive atmosphere. Contact sparking may occur while installing or removing batteries and cause an explosion. Potentially Explosive Atmospheres Turn your radio OFF when in any area with a potentially explosive atmosphere. Sparks in such areas could cause an explosion or fire resulting 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 Areas To avoid possible interference with blasting operations, turn your radio OFF near electrical blasting caps or in a blasting area or in areas posted: Turn off the two way radio. Obey all signs and instructions. Transmit and Receive Procedure Your two-way radio contains a transmitter and a receiver. To control your exposure and ensure compliance with the general population/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, is important because the radio generates measurable RF energy exposure only when transmitting (in terms of measuring standards compliance). Always hold the radio approximately 5cm in front of your mouth with the antenna pointing away from your head. Radio Operation and EME Exposure Unauthorized 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 the belt 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 the possibility of electromagnetic interference and/or compatibility conflicts, turn off your radio in any location where posted notices instruct you to do so such as health care facilities. Aircraft When instructed to do so, turn off your radio when onboard an aircraft. Any use of a radio must be in accordance with applicable regulations per airline crew instructions. Medical Devices Pacemakers The Advanced Medical Technology Association recommends that a minimum separation of 6 inches (15cm) be maintained between a handheld wireless radio and a pacemaker. These recommendations are consistent with the independent research by and recommendations of the 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 Aids Some radios may interfere with some hearing aids. In the event of such interference, you may want to consult your hearing aid manufacturer to discuss alternatives. Other Medical Devices If you use any other personal medical device, consult the manufacturer of your device to determine if it is adequately shielded from RF energy. Your physician may be able to assist you in obtaining this information. General warnings Never use your radio outdoors during a thunderstorm. Keep the radio out of reach of babies and young children. INSTALLATION Removing the belt clip Pull the belt clip latch away from the unit. See picture as right Installing the Batteries FOR USE OF RECHARGEABLE BATTERIES:

If your walkie talkie comes with a rechargeable battery , USB cable, dual USB adaptor and dual USB car charger. The fully charging time is about 12 hours,during charging ,there is red light on the LCD screen meanwhile battery icon will flash,when it is charged full,the Red light will be off. The USB cable, adaptor and car charger will only charge the single ni-mAh rechargeable battery or ni-mAh rechargeable battery pack which provided and not other types of rechargeable batteries.After placing batteries into correct positions, replace the battery cover. Remarks:Dont charge the alkaline battery FOR USE OF NON RECHARGEABLE BATTERIES:

1.Slide down the battery compartment cover. 2.Insert 3 x AAA batteries (not included). 3.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 Indicator The 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 continuously blink until it totally drains the battery voltage where then you will have to replace the batteries. Transmitting Range The talk range will depend on your surroundings and environment it will be affected by obstructions such as hills or buildings. Dont 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 radios indoors or in vehicles. Operating the unit Turning unit on/off:

CTCSS/DCS Press the Menu/PWR button twice and use the Up/ Down to introduce CTCSS/DCS Continuous Tone- Coded Squelch System or CTCSS is a circuit that is used to reduce the annoyance of listening to other users on a shared two- way radio communications channel. It basically allows a private CH on a busy stream. CTCSS = Coded tone controlled squelching system. This allows you to talk on a private sub channel on an active channel. DCS is a digital extension of CTCSS. DCS=DCS is a digital extension of CTCSS.It provides extra,digitally coded,squelch codes that follow after the 38 CTCSS codes. CTCSS 1 to 38 ,followed by DCS 1-83. VOX voice operated transmitter ,it allows you to transmit with your voice without pressing the button. Your communicator is equipped with an adjustable Voice Operated Transmitter(VOX) that can be used for automatic voice transmission.
