2. The antenna is an important part of the walkie talkie, it can not be pulled or held, which will affect the distance of the call.

3. Medical equipment such as ECG monitors are more sensitive to radio frequency signals. If there is no radio frequency shielding capability, keep a certain distance from the walkie talkie as much as possible.

DedicatedPlease protect yourself when fighting the epidemic

When distributing walkie talkies, try to ensure that a dedicated person is dedicated to prevent cross-infection as much as possible

In addition, we must do a good job of disinfection and sterilization of walkie talkies whether it is dedicated or shifted use, wipe with alcohol to inactivate the virus

Alcohol refers to 75% ethanol

Precautions:

1. The COVID-19 virus is mainly spread by respiratory droplets and contact. When using walkie talkies, the distance between the mouth and nose and the device is generally less than 10 cm. Please ensure that dedicated personnel are used as much as possible because shift use will have potential cross-infection risks.

2. Don't use the walkie talkie in the isolation area and the polluted area with the outside world. Make sure to use it separately.

3. The walkie talkies in quarantine and contaminated areas shall be disinfected every four hours, and others shall be disinfected and disinfected once a day.

4. According to the relevant national specific guidelines, alcohol can effectively inactivate the virus. At the same time, inactivation methods and substances are relatively safe and convenient.

5. Alcohol is flammable and explosive. When disinfecting and sterilizing the walkie talkie, you need to turn off its switch power first, and spraying is not allowed.

6. When using alcohol for disinfection, it is advisable to dip a cotton ball and squeeze out the excess alcohol before wiping the body to prevent the alcohol from flowing into the interior and causing malfunction.

7. Personnel who are often exposed to liquids for epidemic prevention and control, such as those who specialize in virus elimination and epidemic prevention, can use waterproof walkie talkies.

Walkie talkie accessories such as batteries and earphones can assist the epidemic prevention staff to maintain a better working condition and have more comprehensive operational capabilities when wearing protective clothing or working with both hands

Precautions:

1. It is best to equip each walkie talkie with two batteries to ensure continuous operation of the walkie talkie under high-intensity work.

2. Try to use original batteries purchased through regular channels, especially walkie talkies with a certain waterproof capability.

3. The charging of walkie talkies should be managed in a unified manner and centralized charging to ensure timely supply and replacement.

4. You can also use the intelligent multi-connected charger to solve the charging problem safely, conveniently, and intensively.
