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.
