Using this walkie talkie set is a breeze. Just insert 3 AAA batteries into each handset (batteries are not included). Turn on the device, set the same channel on both units, and you're ready to communicate. When using outdoors, keep in mind that the range might be affected by obstacles like buildings or mountains. To maintain your walkie talkies, store them in a dry place when not in use. Wipe the surface with a soft, dry cloth regularly. Avoid exposing them to extreme temperatures or moisture. This will help keep your walkie talkies working well for a long time.
