Walkie-talkie Related Knowledge

(1) Regular use of walkie-talkies

1) The walkie-talkie itself has a transmitting and receiving function, which does not need to work with wireless network signals (except networking).

2) Press and hold the PTT button [emission key] (about 2.5-10 cm from the mouth) to talk with the members of the group. When the PTT button is released, it is the receiving state.

3) The walkie-talkie cannot be launched without an antenna, otherwise the power tube is easily burned out.

4) Try not to use a damaged antenna. For example, the antenna rubber damages the bare metal, and contact with the skin during launch may cause slight burns.

5) The battery is charged similarly to the mobile phone. The new battery head is used up two or three times and then charged overnight. After repeated two or three times of charging and discharging, it usually takes about 4 hours to charge. (Note: Battery capacity is 1000 mA)

6) Note: If the walkie-talkie malfunctions, please do not dismantle it yourself and weld it! In order to avoid accidents! Should be handed over to the professional for repair.

(two) walkie-talkie talk distance

The communication distance of the regular walkie-talkie can be up to 8 to 18 kilometers in an open space and up to 3 to 5 kilometers in an urban area. If there is a mountain or high-density building, the call distance will be relatively shortened. If you need more network calls, you need to have network support. By using the relay station, you can make the call distance reach several tens of kilometers.

(3) Battery use matters

1) The original battery or approved battery must be used.

2) The battery electrode is bare and cannot be in contact with the conductive conductor, such as metal, key, jewelry, etc., otherwise it may cause damage to the battery.

3) The charging environment should be carried out in an environment of 5-40 degrees. The battery life and capacity will be affected if the ambient temperature exceeds the specified range.

4) The battery usage time can be up to 8 hours in the case of 5-5-90 ratio (ie 5% emission, 5% reception, 90% standby), and depending on the capacity, quality and frequency of use of the battery Different.

(4) Safety matters

1) Turn off the intercom at the place marked "Close the walkie-talkie". Certain locations may be affected by electromagnetic interference or electromagnetic compatibility, such as hospital medical equipment, aircraft, or certain instruments.

2) When using in a potentially explosive environment, it must be used with a specially certified walkie-talkie (explosion-proof walkie-talkie), and it is not possible to replace or charge the battery in a potentially explosive environment, otherwise it is very likely to cause an explosion or fire.

3) Do not place the intercom in the range covered by the airbag when the car is in use with an airbag. When the airbag is quickly deployed, the intercom opportunities will hurt the people in the car with great impact.

(5) Whether the walkie-talkie can make a call: The walkie-talkie (with networking function) can be used to make calls, but it needs network support.

(6) Warranty matters

1) The product host is guaranteed for 18 months, the battery, charger and antenna are 6 months, and the headset is not guaranteed.

2) The product is not protected by water, self-disassembly, repair, modification, etc.

3) The date of purchase label, body number altered or unrecognizable.
