In your daily work, have you find in the same working, why do other guys’ walkie talkie always use longer time than yours? Maybe his battery capacity is higher then yours. But if you mastered those correct charging skills of walkie talkie battery, you will last longer then the same battery capacity from others’ two way radio! When we charge batteries, we should know them in different types should use different charging way: Li-Ion battery: Lithium-ion batteries have no memory effect, so they don’t need to be activated. You just need to charge the battery when the power is less than 10% or when the walkie talkie is low ( battery voltage may affect the talking range). When the battery is full, you can keep use your walkie talkie. PS: Try to charge the battery full before using them, that is more conducive to protecting the health of the batteries. Ni-MH battery: Nickel metal hydride batteries have a memory effect, so regular charge and discharge management is required. First use of Ni-MH batteries required activation. The first three times’ charge should Continuous Charge more than 12 hours, then the battery has been activated. PS: The memory effect of Ni-MH batteries is weak, but we suggest you charge the battery when it’s empty. And please full charge at one time then use it, this rational use keeps the battery get longer cycling life. Ni-CD battery: Nickel-cadmium batteries have a stronger memory effect then Ni-MH battery. The Ni-CD battery also need to be activated. The first three times’ charge should Continuous Charge more than 12 hours, then the battery can be activated. PS: The Ni-CD batteries have a strong memory effect, it’s necessary to ensure to charge the battery after it’s empty. If you usually charge the Ni-CD battery when it still have power or use it when it’s no full charged, that may cause the battery has a bad memory effect. That will cause the batteries greatly shorten the battery life. Recommendations: Ensure the Ni-CD battery is empty ( when you pressed the PTT of walkie talkie, it can’t normal transmit) before you charge it . Full charge the battery before you use it. Precautions: 1. Chargers of different types of batteries (such as Nickel-Cadmium batteries and Lithium-Ion batteries) should not be mixed, otherwise the battery will be damaged; 2. Try not to charge the battery on the radio. If the battery charged with radio, the radio should be turned off, otherwise the battery life will be seriously damaged. 3. Lithium battery relative to other batteries, do not need to pay attention to it much, be careful not to over-discharge and over-charge. Please distinguish between different batteries and treat them differently in order to maintain the battery life and last the battery. 

Many users are particularly concerned about the talk range of the two-way radio. In fact, this is a relatively complicated issue. Without an accurate statement, it is impossible to easily believe some exaggerated advertisements. Generally speaking, the talk range of the two-way radio depends on the following aspects: 1.the transmission power of the two-way radio; 2.the topography of the location; 3.frequency band and antenna gain of the two-way radio. Take a walkie-talkie with a power of 4W as an example, the open area can pass 3-6km, and in the city or mountain area, it is 1-3km because it is blocked by buildings or mountains (if used indoors, the distance is closer). If you want to increase the talk range, you can choose a higher gain rod antenna. If it is really necessary to further increase the talk range, consideration should be given to setting up a relay station, and the talk range can reach more than 10km after the relay station is set up. Open-band radios (civilian walkie-talkies) are 20 channels specified by the Ministry of Information Industry. In the 400MHz frequency band, the power cannot exceed 0.5W. The talk range is closer than that of professional radios with higher power. The urban area is 300-1500 meters and the open area is 1000- 2000 meters, can not increase the talk range by setting up repeaters.

Some new hams (fans of two way radio) may have questions about how to use two way radios and what should we pay attention to? Let’s see how to operate walkie talkie and what should we noticed: Operations: 1. When we press the PTT (Push-to-Talk), the indicator is red, it means the walkie talkie is in the transmit state, we can speak when this moment. At this time, who are in the same frequency with you can received your signal and listen what you are saying. 2. Change the frequency: Rotating the channel knob on the top or use the numeric keypad. When you are in the same frequency then you can talk. 3. When you want to use two way radio with other people, but you don’t know his frequency because he don’t have a screen. You can use the SCAN function. 4. When pressing the PTT, the indicator light is green, means that the walkie-talkie is in a mandatory receiving state. Notices: 1. Ensure the walkie talkie in vertical position when you transmit. When you speaking, keep the distance between walkie talkie and your mouth 3-5 cm. 2. Don’t turn off or turn on many times when you are using the walkie talkie. Please adjust the volume to the appropriate state. 3. Don’t twist the antenna when you are using two way radios, and do not bend the antenna. Do not use the antenna when it’s broken, which will affect the radio. In severe cases, the instantaneous voltage of the intercom will burn the machine. 4. In the rainy weather, the radio should be kept as dry as possible. The radio should not be placed under the air conditioner, and it is easy to enter the water to oxidize the circuit board. Waterproof cover should be worn when it is used outdoors on rainy days. For some waterproof walkie-talkies, it should be kept as dry as possible also. 5. If the walkie-talkie case is mixed with dirt or grease. Do not put it in the water for cleaning. Wipe with a neutral detergent velvet. Some waterproof walkie-talkies can be flushed but the water pressure should not be too high. 6. If the radio had already entered water, the battery should be deducted immediately. Don’t use the radio at this moment, try to dry it and send to the service center as soon as possible.
