Radiation and Antennas
2024-12-05
Keep the antenna 5 to 7 centimeters away from the body during calls to reduce radiation, and try not to use exposed antennas.
Comparison between walkie-talkies and mobile phones
Radio walkie-talkie equipment holds an irreplaceable important position in global communication systems, used for communication and command scheduling among team members, improving work efficiency and rapid response capability in handling emergencies, receiving high praise from users across various sectors. In today's world where new communication products like mobile phones are still popular, the functions of walkie-talkies remain irreplaceable.
Differences between walkie-talkies and mobile phones
Walkie-talkies require a one-time investment and charge based on call time, allowing for one-button communication without dialing and waiting for connection. They support call queuing, multiple single calls, group calls, and one-on-one communication without disconnection. Suitable for work scheduling, personal use, emergency communication, and handling sudden events; mobile phones are suitable for daily communication.
When using a walkie-talkie, check the channel being used each time it is turned on to avoid unnecessary mistakes.
When using a walkie-talkie, keep it vertical with the microphone 3-5 centimeters away from your mouth.
Avoid using the walkie-talkie in high temperatures, humidity, or near flammable gases; stay away from gas stations.
When using a walkie-talkie, handle it gently and do not hold it by the antenna part, as this may damage the antenna and affect communication.
Transmitting consumes a lot of power, while receiving consumes less; conserve power while on standby.
For charging, it is best to charge for more than 8 hours during the first charge; otherwise, it may affect future charging efficiency and battery life.
Do not frequently turn the device on and off during use; also adjust the volume to a comfortable level for your hearing.
Only use antennas that are original or approved by the manufacturer; unapproved or modified antennas may damage the walkie-talkie or violate regulations set by the Information Industry Radio Management Committee.
The wireless part of the walkie-talkie should not be unscrewed; otherwise, it may easily damage its power tube during transmission.
Do not use damaged antennas; if a damaged antenna comes into contact with skin during transmission, it may cause minor burns.
Batteries must be original or approved batteries from the manufacturer, and charging should be done in an environment of 5-40 degrees Celsius. Exceeding this temperature range may affect battery life and could prevent it from reaching its rated capacity.
To avoid problems caused by electromagnetic interference or compatibility issues, please turn off the walkie-talkie in places marked with 'Turn off walkie-talkies' signs. For example: hospitals, airports, gas stations, etc.
After long-term use of the walkie-talkie, the control knobs and casing can easily become dirty. Please remove the control knobs from the walkie-talkie and clean the casing with a neutral detergent and damp cloth. Using chemical products such as stain removers, alcohol, or sprays may damage the surface and casing of the walkie-talkie.
