How to maintain the walkie-talkie?
1. For long-term use of walkie-talkies, it is necessary to regularly scrub the buttons, control knobs and casing, which are easy to dirt. It is best to wipe gently with a neutral detergent and a damp cloth to avoid using those highly corrosive stain removers, which can easily cause damage to the surface of the walkie-talkie.
2. The normal thing is to pick up the walkie-talkie body, do not directly carry the walkie-talkie antenna, and gently place it in a safe position after use.
3. There may be headphones, data transmission and other interfaces on the side of the walkie-talkie, remember to cover the dust cover when not in use.
How to reduce walkie-talkie radiation?
1. When pressing and holding the PTT button of the walkie-talkie for intercom, keep the mouth at a perpendicular distance from the walkie-talkie25 cm 5 cm.
2. Although the walkie-talkie will produce a certain amount of radiation in wireless communication, it will not cause harm to human health, try not to turn on and off many times during use, and the volume should be adjusted to an appropriate size.
How far is the walkie-talkie communication distance?
The daily communication distance in the open area is about 8 10 km, and in the urban area it is 3 5 km, especially in the case of tall buildings and high mountains, the communication effect is poor, and the communication distance is shorter. The use of networking, that is, the relay station to automatically receive the signal, can be amplified and **, so as to expand the communication coverage and extend the call distance. Many communication blind spots, such as basements, fire escapes, etc., can be enhanced by repeaters, and handheld walkie-talkies can also communicate normally.
The main reasons that affect the communication distance of the walkie-talkie?
The main reasons that affect the distance of the communication radio are power, sensitivity, the height of the antenna, the length of the type of antenna, the terrain and landform where the walkie-talkie communication is located, whether there are tall buildings and metal objects in the surrounding environment, etc.
What should I do if the walkie-talkie gets into the water?
1. The walkie-talkie should be turned off immediately after water ingress, and then the battery should be disassembled immediately.
2. After the battery is disassembled, shake out the water of the battery and the fuselage respectively, and dry it in a ventilated and dry place (avoid exposure to the sun).
3. Confirm that the fuselage and battery have no moisture, install it back to test whether it can be used normally, if not, it should be sent to the maintenance center as soon as possible.
What is Intermodulation Interference?
Two or more signals are modulated in a nonlinear transmission circuit to produce a combined frequency close to the desired signal frequency, thus causing interference to the wireless radio system.
What is the power saving function?
In order to save electricity and extend the standby time, the walkie-talkie will work in the way of shutting down for a period of time and turning on for a period of time without operations such as transmitting and receiving and pressing buttons, which is the way to save power. When the walkie-talkie is operated on, it will immediately exit the power-saving state and enter the normal communication state.
