Q:Why cordless phones are made from NiMH batteries instead of lithium batteries?

The lithium battery is more fragile, more not overcharge protection circuit and the use of off the shelf is also too simple (just off protection). Even with the protection of overcharge protection, voltage is too high (usually 4.3V or higher, as the last protection measures to be used), and the protection, need to reset is available, it is not suitable for use in here.The solution is to make use of TL431 DIY, a precise high performance regulator tube. Among them, Vref=2.5V, select R1=68k, R2=100k, you can do VKA=4.2V, and the characteristics of very steep. Before reaching 4.2V, the current is very small. Once it reaches 4.2V, it is stable at 4.2V. The excess current is absorbed by TL431, and the maximum absorption capacity is 100mA. The regulator is connected to the battery in parallel to ensure that the battery voltage is no more than 4.2V. Before the battery voltage reaches 4.2V, the circuit has no current flow, and all the current flows into the battery.

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:How do landline phones and cell phones work in cordless telephones?

The cordless phone is different, it requires both sides to exchange each other or provide the relevant signal before the completion of communication building process, as follows: the host realizes how to control a mobile phone off hook action (i.e., mobile phone dialing, heard dial tone) mobile phone users want to make a local call, press the mobile phone off hook key encoding integrated circuit machine (according to the address code, can produce multiple encoding) and pilot oscillator begins to work, the sum of the two output composite encoding pulse train, the signal is amplified by the mobile phone in the FM circuit, the antenna is shoot out. The host receives the signal, after the change of frequency of signal separation, the separation of the encoding signal for host computer and mobile phone to confirm contact, to prevent other mobile phone theft.

Q:How does the BBK 76E cordless phone set up the sound?

1: right softkey shortcuts - Volume - ring volume.2: menu - scene mode - personal settings - Volume - ring volume.
