Education supplies wholesalers must know 4 ways to improve the call distance and call clarity of toy walkie-talkies.
1. Make sure the battery has sufficient power. When the battery is low, the call sound will be noisy.
2. Choose an environment with open terrain and no obstacles. The call distance in densely built areas will be greatly reduced.
3. Avoid signal interference such as power equipment, high-voltage lines, and metal structural objects.
4. When speaking, try to be as close to the Microphone as possible so that it can be heard more clearly.
