Scramble system transmitter for hearing
SCR-100T

Outline
  • For the scramble transmitter (SCR-100T) , an exclusive receiver must be used. No conventional receiver sold in the market is available with the transmitter.
  • It is system that 4 kinds carrier (dispatch frequency) is converted into short which is 20 times in one second.
  • The exclusive receiver is restore as it automatically traces to the carrier. Due to a difference on the order of repetition, the exclusive receiver (SCR-100R) is pair with the transmitter in use (all of six kinds of H. I. J. K. L. M.).
  • For ALC (Automatic Loudness Control) is built in, it can be heard loud sound and faint sound in the same level and it doesn't crack even on big voice.
  • The available distance of the wave is about 200 meters on flat ground. If Yagi antenna is used with the receiver, the distance will be extended to about 300 meters.
  • The battery life (lithium battery CR-12600 SE) is 5 days in use continuously. Also, alkali dry cell No.5 batteries (2 pcs) are useful but, the battery life is 2-3 days. If the battery adapter (AD-L) is used, battery life is to be extended to one month.
Directions
  • It slides and removes, pressing down the back lid of a main part with the thumb, polarity is put in for a battery to prevent mistakes, and a lid is shut. If an attached antenna is attached, finally preparation is. Dispatch will be begun if the slide switch in an antenna side is put into the direction of red mark.
  • The rest is only established in a required place.
  • It warns against plugging up the hole in which the sound of a microphone is brought together.
  • Electric wave efficiency becomes [ the direction where the attached antenna used 1/4 wave of straight-wire antenna from the helical antenna ] good about ten percent.

Notes
  • Since micro parts have condensed and incorporated s of the precision parts are carried out, please do not carry out usage which gives a shock.
  • Since the attachment portion of an antenna tends to break, be careful of handling enough.
  • Please do not attach a powerful magnet to a main part. It stops functioning at an instant like a magnetic card. It does not return, unless it readjusts.
