Scramble system receiver with remote control function
SCR-200R


Outline
  • It is the exclusive receiver of a remote control formula scramble transmitter (SCR-200T). If the switch of a receiver is put in, a remote control formula scramble transmitter will begin to send an electric wave.
  • The electric wave of the transmitter for hearing of the system which changes four kinds of electric waves 20 times in 1 second is received, and it gets over.
  • Appearance and a performance are almost the same as that of KUR-400, and it is only micro that thickness increased by 4mm. However, the electric wave of a common transmitter is unreceivable.
  • It restores to a receiver on the career of a transmitter in the form which carries out an automatic tailing synchronization. The click sound at the time of a synchronous change rate is slightly mixed with receiving sound.
  • It cannot be heard that it is not the receiver which became the transmitter and the pair by the difference in the order of a repetition of a career. There are six kinds (H, I, J, K, L, M) of kinds of system.
  • Troublesome operation is not required at all. If a power supply switch is put in, it is after [ 3 seconds ] receivable.
  • A battery uses one CR-2 of a lithium battery. Continuous use is carried out and there will be a battery life on the 2 days or more.
  • The model of special frequency can also be manufactured. (It becomes less than [ 320MHz + - 2MHz ], a transmitter, and a pair.) Time-for-delivery one month. Price is 1.5 times
Directions
  • If the battery lid on the back of a rear is slid back, the place into which a battery is put is visible. Lithium battery CR-2 are used. It is careful of the polarity of a battery to prevent mistakes. The minus side of a battery is hit and put into a spring. When taking out, the plus side of a battery is taken out with the point of a nail.
  • An attached helical antenna is put in the antenna terminal of the front of a main part. Subsequently, knob of a small slide switch written to be ON-OFF of the side It moves in the direction of ON. It will be in a state receivable now.
  • It is heard using an earphone. A front volume regulation knob (VOL) is turned until it becomes suitable volume.
  • If a power supply switch is put in, it will begin and for 3 seconds will send an instruction electric wave to the receiving circuit by the side of a remote control formula scramble transmitter. The internal receiver by the side of a remote control formula scramble transmitter is operating a short time (30mS) 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 3 seconds. Perception of it of the internal receiver by the side of a remote control formula scramble transmitter begins to send an electric wave. Although the dispatch electric wave by the side of transmission is henceforth disconnected at intervals of about 4 minutes, the direction of a remote control formula scramble receiver side will issue instructions of re-connection at an instant, if the electric wave by the side of a remote control formula scramble transmitter is disconnected. Therefore, unless the power supply switch by the side of a remote control formula scramble receiver is cut, it can continue receiving continuously. If the power supply switch by the side of a remote control formula scramble receiver is cut when stopping, dispatch of the electric wave by the side of a remote control formula scramble transmitter will also go out automatically less than several minutes.
  • It sounds [ 1 time, 3 times, or ] "bhutsu" and "bhutsu bhutsu bhutsu" at the time of re-connection. It repeats until it synchronizes with a dispatch electric wave by the receiver side. It does not become 4 times or more.
  • It repeats until it will receive the electric wave of "bhutsu bhutsu bhutsu" and a transmitter, if it becomes beyond [ receivable ] distance. In this case, please put in a switch again in the place which cuts the switch of a receiver and can be received.
  • When the sound from a transmitter is loud, the sound "bhutsu bhutsu" is somewhat mixed at the time of a synchronous change rate.
  • When carrying out automatic recording, it is used by putting an attached recording code in the earphone terminal of a receiver, and the external microphone terminal of a recorder. The position of the volume in this case is carried out to the position which hears it by the earphone and can be heard ordinarily. A receiver, a recorder, and cases are put together and it is made not to install. When used by sticking, putting in in between etc. should carry out, insulate and install paper, a cloth piece, etc. Unless cases are insulated, it may not be recorded normally.
  • If battery voltage is lost, a small red lamp will light up in the way in the inner part of the crevice between an antenna terminal and volume. When normal, this lamp is turned on at the moment of putting in a power supply switch for a moment. If the voltage of a battery becomes 2.7v or less, the light will be switched on continuously. For a while, although a receiver can operate, please replace it with a new battery a little early.

Notes
  • When not receiving, the switch of a battery is surely cut. When you do not use for a long period of time, please take out a battery and place it. Internal parts are damaged when a battery carries out a liquid leak.
  • Since the inside consists of precision parts, please do not drop it, or do not apply power which is twisted strongly. please carry out as carefully as possible, the desorption of an antenna also having both sides for a root portion with a finger, and turning to right and left little by little slowly -- please do not attach a powerful magnet to a main part a magnetic card -- it stops functioning at an instant It does not return, unless it readjusts.
