Transmitter built in various electric apparatuses with a sound starting system.
KNN-110


Outline
  • By connecting with an home electric light line, this device is a hearing transmitter which made the battery unnecessary.
  • It amplifies and sends also to minute sound. a battery -- since it is unnecessary, it can be used semipermanently
  • Since the outside is made very small, it can be made to be able to build in the various apparatus using the home electric light line, and can use.
  • Since it is a sound perception starting dispatch system, an electric wave is sent only when there is the above sound (voice) to some extent. Therefore, it is hard coming to carry out discovery by the locator.
  • An exclusive receiver (KUR-400) is used for receiving.
  • It can be heard in the place about 1km away using relay equipment (RP-300A).
  • Automatic recording for 5 hour is made using KKCR-360.
  • Prolonged automatic recording is made using the recorder with a commercial voice starting recording function.
Directions
  • When installing in the connection socket of a wall etc., it connects with metal portions, such as the root of an electric light line, in attached clip code. After thrusting an attached clip code into this device screw terminal first, it adds the metal portion of an electric light line with a clip, and connects.
  • The power of collecting sound becomes weak and it becomes impossible to gather a small sound, if sealed completely, when used by building in an electric product etc. Moreover, tone quality also becomes bad and the degree of plainness becomes remarkably bad. Although the portion of a small hole is in the place by the side of opposite [ of this device / two / of a screw terminal ], since sound is gathered in the portion, the portion of a hole is stuck to the crevice between the exteriors of the apparatus made to build in. It fixes and installs with a gummed tape, a cellophane tape, etc.
  • The notification distance of an electric wave is 50 or about 150m. In the place where the inside of a building and the house build and are crowded, how to transmit an electric wave becomes bad and a receivable distance becomes short.
  • An exclusive receiver (KUR-400) is used for receiving. Or commercial UHF band Although it is receivable with a multi-channel receiver, tone quality is bad or notification distance becomes short. the noise which the receiver itself takes out with a commercial general-purpose receiver especially when hearing whisper voice etc. -- and it cannot catch Please be sure to use an exclusive receiver.
  • Automatic recording can also be carried out to the recorder with the commercial voice starting recording function using the recording code of attachment in an exclusive receiver (KUR-400). When you make it automatic recording, please be sure to carry out a check of operation. It checks whether make sound with pocket radio etc., an electric wave is made to send, there is no noise in a receiver, and it is finely audible. The recording code of receiver attachment is put with after that in the earphone terminal of a receiver, and the external microphone terminal of a recorder, it sets to sound starting, and a recording button is pushed. Since it is the mechanism recorded only when sound has been noticed, when required, it can be heard collectively later.
  • If the newest digital IC recorder is used, a part for 10 hours can be recorded continuously, moreover, it takes in in a personal computer and preservation reproduction can be carried out.

Notes
  • Since a terminal portion may break when it binds tight not much strongly although it is a screw system when connecting an attached code to this device, be careful. If too weak, it will become the cause of noise generating. When you attach this device in a direct electric light line, please take great care about the electric shock accident. Please work after carrying out dropping a breaker etc.
  • Please do not attach a magnet in a main part. An electric wave does not become weak or it stops coming out..
