FAQ (Frequently Asked Questions) Q: When I use Intercom, I frequently experience noise and disconnections. A: Bluetooth Intercom uses 2.4GHz ISM band. This ISM band is being used for many applications, such as Wi-Fi, wireless CCTV, garage door remote control, traffic control signal etc. Therefore, in the city area, there are many ISM band frequencies being used and these cause interferences. If the other ISM band equipment is closer than your intercom partner, there would be noise and disconnections. High voltage power line can also cause the same phenomenon. This phenomenon is inevitable with Bluetooth products. Q: When I use Intercom, I feel more noise and disconnection toward a certain direction. A: Bluetooth ISM band is also a part of radio frequency. Radio frequency has very similar character to the light. Radio frequency cannot go through water, soil, rock, metal plate and human body. The human body consists of 70% water. Therefore, Bluetooth communication cannot be connected well through body. This phenomenon can happen when you have your Smart-phone in your back pocket. Q: Battery life became shorter. A: For Life cycle of Lithium Ion, Lithium Polymer battery, manufacturer guarantees only 300 times of full charges and discharges. 300 times of life cycle means, if you use the full capacity of the battery every day, you can use it only for about one year. If you use half of the battery capacity every day, you can use it for about two years. If your battery capacity went down too low and you cannot use it for enough time in your normal usage, please contact our service center to have a battery replacement service. Q: I cannot use intercom with a range of 700m as described in the specification. A: As described in the answer above, the 2.4GHz ISM band frequency gets much interference by other ISM band applications in the city area. Interference cause noise, disconnection and shortened range. This is inevitable since the 2.4GHz ISM band is free of charge and has no obligation of registration. That is why ISM bands are so popular. However, at the seaside, without any other ISM band interference and no obstacles between two riders, you can have even better range than 400 meters.
