Use common sense
A wireless intercom for everyday use common sense
1) with its own radios transmit and receive functions, without the help of Wi-Fi signal to work (except networking).
2) wireless radio speech just hold down the PTT key [PTT] (approximately 2.5-10 cm from the mouth) to talk with members of the group, release the PTT button when receiving state.
3) antenna radios can not do without, or walkie-talkie power tube easily be burned.
4) Do not use a damaged radio antennas, for example: radio antenna rubber damaged, bare metal in contact with the skin launch may cause minor burns.
5) walkie-talkie batteries and cell phone charging principles method is similar to the new radio batteries at the beginning of two or three should interphone battery to charge overnight, then finished, two or three times repeated charging and discharging, the usual way radio battery charging only about 4 hours can be filled. (Note: The battery capacity to 1000 mA for example)
6) Of particular note is that the radios such as failure, please do not own overhaul, welding, etc.! To avoid accidents! Should contact the vendor or wireless walkie-talkie radio to the factory for inspection and maintenance.

Second, wireless intercom distance calls
I believe many people buy wireless walkie-talkie, it is usually very concerned about the walkie-talkie distance calls. Conventional civilian radio communication distance, are generally restricted to a different use of the environment, for example: using walkie-talkie in the open distance calls up to 5 to 18 km, the urban use of the words up to 3 to 5 km, if the mountains or the case of high-density buildings block, intercom distance calls will be relatively short. For longer distance calls shall be conducted in network support, through the use of radio relay station network, make intercom calls distance of tens of kilometers.

Third, wireless walkie-talkie battery use common sense
1) must use walkie-talkie radio battery Original battery manufacturers or approved batteries before use.
2) walkie-talkie battery electrode exposed, it is not in contact with the conductive conductor, such as: metal, keys, jewelry and other conductive body, as this may cause damage to the radio battery is damaged person.
3) walkie-talkie battery charging environment should be 5 to 40 degrees environment. Ambient temperature exceeds the specified range, walkie-talkie battery life and capacity will be affected.
4) walkie-talkie battery usage time in 5 ~ 5 ~ 90 percentage (ie 5% transmit, 5% Receive, 90% standby) cases are generally able to use the time up to 8 hours, and the use of time depending on the walkie-talkie battery capacity, quality, frequency of use are different.

Fourth, the use of safety precautions radios
1) at the mark "Turn the transceiver," the place should turn off the wireless radio transceiver. Due to electromagnetic interference or electromagnetic compatibility in the case will affect some places.
2) when used in a special environment, you must use special certification through walkie-talkie (** intercom) before use, and do not replace the radio in a special environment, the battery or charge the battery, or they may easily lead to fires and other hazards.
3) car with airbags, do not use the wireless radio on the balloon involved in range. Prevention balloon rapidly when radios will greatly impact injuries as occupants.

Five, walkie-talkies can call
Wireless Intercom (with networking capabilities) can be used to make calls, but requires network support.

Six, warranties radios
1) radios generally have the warranty period, basically 18 months, walkie-talkie battery, Battery Charger, Antenna these general warranty period of six months.
2) Wireless Intercom product water, disassemble, repair, modification and other man-made damage is not covered under warranty. 3) radios generally are affixed on the machine date of purchase labels, marked with serial numbers, etc., if the mark is altered or illegible are generally not warranty, so to protect these important mark. Not data.
