1. In cars with airbags, do not place the walkie-talkie within the area that may be involved when the airbag deploys. If the walkie-talkie is within the area that may be involved in the deployment of the airbag, once the airbag rapidly deploys, the walkie-talkie may injure the occupants of the vehicle with the tremendous impact.
2. In potentially explosive atmospheres or situations, turn off the intercom unless it is specially certified. In potentially explosive atmospheres, electrical sparks can cause an explosion or fire.
3. Do not replace or charge the battery in a potentially explosive atmosphere. Installing and removing the battery can cause contact sparks and result in an explosion.
4. Turn off the walkie-talkie before approaching the blasting area and the area where the detonator is located to avoid a possible explosion.
5. Use the company's original or approved batteries.
6. If metal conductors such as jewelry, keys or beads practice touching the exposed electrodes of the battery,
7. Charging should be done in an environment of 5~40 degrees.
8. To avoid problems caused by electromagnetic interference and/or electromagnetic compatibility, the intercom should be turned off in places where a sign is posted to turn it off. Examples include hospitals or other settings where healthcare medical equipment is used. Walkie-talkies should also be turned off when traveling on airplanes, upon request.
