recording device off-line independent work, and there is no need to be linked with computer operation, large storage capacity, can be achieved only with ordinary telephone connections recording functions, and direct telephone link can also be connected with telephone ext. Use simple, connected electricity supply and telephone would be connected. The pronunciation uses our company the special-purpose form, and can be converted to WAV format audio effects clear, permanent retention through USB data line connected to the computer, it can automatically backup for recording documents, copies of video and audio document management.  
The recording capacity sign matches is 140 hours, may expand most greatly to several hundred hours, may adjust the clause using the software which the table of contents demonstrated and shake in front of the bell FSK, DTMF comes the electricity examination establishment; Select the new record pattern when the customer, the system provides the automatic pronunciation gain function, further balances the bilateral telephone conversation volume, achieves the good playback effect. Performance characteristics:  
1. Off-line independent work volume precision
RIPE CF cast recording device does not need to connect computer. You only need to connect telephone and turn on power; the recording device could start work.  
2. Revolving records automatically update
When the voice capacity to the limit, the system will automatically remove the first recording of the information, allowing the system to maintain perennial latest recording information.
3. Both sides of the phone recordings without interference  
Comprehensive records of telephone calls from both sides of information without the interference of the phone, a voice recording products are the core technology. Current telephone lines and equipment using high impedance to connect with the telephone system can record the signal lines without interference from the parties on the phone.  
4. Sound recordings of repeat  
Sound recordings should be able to easily repeat through multiple channels to achieve information on the use of sound recordings, and this is the most important user of the telephone recording system. You can repeat through networks, may adopt the form of sound in computers repeat to achieve.  
5. Efficient voice compression technology
Voice compression technology is the core technology telephone recording devices. Use of voice compression can reduce storage space by sound recordings, lowering the cost of storage equipment. Thus, the storage space in the same size, can keep more records, greatly reducing the cost of storage equipment.  
6. Flexible and rapid access and retrieval
Each record will have a telephone recording multiple attributes, such as primary numbers, coming numbers, recording time, the length of calls, etc., while recording device capable of providing a single conditions, such as multiple search options portfolio conditions, rapid and accurate information from qualified search result.  
7. Provide effective means of data backup  
For some users must prolonged preservation, and for some users, only a shorter period of record-keeping can be. Therefore, in response to different user needs, data backup can take different forms, either hard disk backup, optical disk backup and tape backup, etc.  
8. Statistics printing function  
The synthesis management, the tabulation printing needs the telephone project content (telephone number, telephone conversation time, telephone conversation length, amounts to telephone conversation length and so on), facilitates the management, the output is convenient.
9. Competence management functions  
After encryption, without the owners I authorized to listen to the recorded voice message; Even in non-encrypted mode, to delete records information, there is a need to authorize the password, double insurance, more information to ensure its security and reliability.
