Using this Walkie Talkie set is easy. First, insert 3 AAA batteries into each handset. Then, turn on the devices and set them to the same channel for communication. When using outdoors, keep the antennas straight for better signal. Remember, the batteries are not included, so you'll need to buy them separately. To keep your Walkie Talkies in good condition, store them in a dry place when not in use. If the devices get dirty, you can use a soft, dry cloth to clean them. Avoid exposing them to extreme temperatures or moisture as it may damage the internal components.
