A.C line direct connection type
Minute sound hearing micro high power transmitter by remote control
KRT-800TA

Outline
  • It is an electric light line direct connection type remote control formula minute sound hearing transmitter. A remote control receiver (KRT-800R) and a set use.
  • Since a battery is unnecessary from the model which connects with an electric light line directly and is used for it, once it installs, it can use semipermanently.
  • It is completion if it puts on a place to hear the inside of the socket box of a wall, and electric appliances etc. It is immediately receivable if the power supply switch of a remote control receiver is turned ON. If the switch by the side of reception is cut when stopping, dispatch of the electric wave by the side of a remote control transmitter will also go out automatically. An unnecessary electric wave is not sent. The notification distance of an electric wave is about 400m in prospect distance. The electric wave output is increasing for a while from the battery formula.
  • In order to gather electric wave efficiency, the antenna of exclusive use is attached.
  • Since the installed remote control transmitter does not always send an electric wave, it is asked to others, or a possibility of being discovered with a discovery vessel etc. becomes closely that there is nothing.
  • Although the number of standard articles is E, arbitrary frequency can be manufactured if it is between 315Mhz - 320Mhzes. It becomes a receiver and a set.
Direction
  • When installing in the wall socket of a wall etc., it connects with metal portions, such as the root of an electric light line, in clip code.
  • 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. Since sound is gathered with a microphone, a microphone portion is made to adhere 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.
  • A remote control receiver and a set use a remote control transmitter. In a standard article, an internal transmitter becomes only F channels [ one ]. If the power supply switch of a remote control receiver is put in, it will begin and for 2 seconds will send an instruction electric wave to the receiver by the side of a remote control transmitter. The internal-organs receiver by the side of a remote control transmitter is operating a short time at intervals of 2 seconds, in order to save a battery. Therefore, sending an instruction electric wave only at the beginning which put in the power supply switch is continued for 2 seconds. Perception of it of the internal-organs receiver by the side of a remote control transmitter begins to send an electric wave. Although the oscillation electric wave by the side of transmission is henceforth disconnected at intervals of 4 minutes, the direction of a remote control receiver side will issue instructions of re-connection at an instant, if the electric wave by the side of transmission is disconnected. Therefore, unless the power supply switch by the side of a remote control receiver is cut, it can continue receiving continuously. If the power supply switch by the side of a remote control receiver is cut when stopping, dispatch of the electric wave by the side of a remote control transmitter will also go out automatically less than several minutes.
  • When carrying out automatic recording combining a commercial recorder, it is used by putting the recording code of remote control receiver attachment in the earphone terminal of a remote control receiver, and the external microphone terminal of a recorder. A receiver, a recorder, and cases are put together and it is made not to install. When used by sticking, in between, on both sides of paper, a cloth piece, etc., please carry out and insulate and install. Unless cases are insulated, it may not be recorded normally.

Notes
  • When you attach this device in a direct electric light line, please take great care about the electric shock accident. In the case of electric appliances, please work after pulling out AC code. In the case of the wall socket box , once you drop a breaker, please work. When you install in the fluorescent light of a ceiling, please choose and attach the fewest portion of generation of heat. Electric noises (hum etc.) enter in the place to attach. When you attach, please receive and be sure to check.
  • Since the condensation internal organs of the precision parts are carried out, please do not carry out usage which gives a shock.
  • Please do not attach a magnet. An electric wave output becomes extremely bad. It will stop returning, if it does not readjust even if it removes a magnet.
