Q:What's the distance of a cordless phone call?
Actually, there is a nominal value on the manual of cordless phones. Ordinary cordless phone calls are not too far away, although the theoretical value is very high, but in the absence of obstructions, if the use of the family, because there are obstacles so can only meet about 150 square meters of the house,.
Q:Does a cordless phone have to be hosted by a host?
It should be said that there must be a wireless transmitting part can use W12 charging seat has a wireless transmitting circuit is a composite machine tool of the wireless transmitting circuit and receiving circuit for duplex transmission
Q:Cordless phones and mobile phones, which are less harmful to the human body?
Cordless phones are very small compared to mobile phonesThe larger the transmitting power of the cordless phone, the farther the calling distance is, the greater the radiation of the electromagnetic wave; and the cordless telephone, which meets the national standard, will not affect the human body. China Radio Management Committee clearly stipulates that the transmitting power of cordless telephone set, the machine shall not exceed 20 MW, the open call distance of about 300 meters, and the frequency between 45 to 48 MHz for cordless phone use, radiation power is so small in the low frequency range is very small.
Q:Is there a cordless phone with a main computer and no external AC?
Cordless phones on my desk don't use alternating current. Powered by a mobile power supply. Power outages can be used. The premise is that my host needs 5 volt DC power.
Q:Which brand is the furthest distance to use?
The Radio Regulatory Commission of our country stipulates that the effective distance of cordless telephone is 50 meters. It is illegal to exceed this distance, especially imported. They do not meet the requirements of our country, and use the outdoor antenna. Cable television in my home was seriously disturbed by the computer in 1990, and later it was checked out by the localizer.
Q:What's the difference between a cordless phone and a master slave machine?
The mother machine is double, but also by the host and slave machine is composed of two parts, telephone line, sub machine through the wireless telephone, mother can also call.
Q:Ask for the meaning of several buttons on the cordless phone!
Exiting is exiting the current operation.Turn frequency is when your call is not very clear, click, will go to another frequency, this is manual frequency conversion, such as BBK are automatic frequency conversionDeleting bits means deleting the previous number when you dialThe R key is used in conjunction with program controlled switches and can be used for telephone switching or three party calls. (R key, including the "*" key, "#" are the keys for SPC implementation of special service set, (in the use of "*" key and "#" button when users must be registered in the Bureau of the service can be realized, the "R" key can switch through the internal implementation the telephone switching function).
Q:The home was originally a cord with a rope telephone, now how to change cordless telephone use, you can not change
That is, the telephone and the plane can be separated, do not call the telephone beside the plane.
Q:Motorola D10 cordless phone with a large number of rechargeable battery 7 okay? Can you use 800mAh or 900mAh?
Capacitance, in theory, is bigger, the better, but some batteries in front of large capacity batteries, sometimes happen, suddenly the battery can not charge, the greater the capacitance, the longer the standby time.
Q:Why cordless phones are made from NiMH batteries instead of lithium batteries?
Very simple to measure with a multimeter, my home phone, open circuit voltage reached 4.5V, while the battery is charged to 4V, the charging current is still 45mA. For Ni MH battery pack 300mAh, due to the use of the phone are regularly inserted into the power supply, which caused continuous charging, overcharge is so often, up to 0.15C, so the battery will soon die be not at all surprising.The solution is to replace it with a lithium battery. The rated voltage 3.6V is the same as that of the 3 Ni MH batteries.
