Small 2 channels receiver with high sensitivity
KKZ-100

Outline
  • They are small [ of the various transmitters for hearing ], and an exclusive sensitivity 2 channel receiver.
  • Since the crystal is used for the local dispatch circuit, there is very little phase noise and it demonstrates might to reception of minute sound.
  • Directions are immediately [ very ] receivable at simplicity and one-touch.
  • It is the small and lightweight receiver of the size which hides in a breast pocket.
  • It ties to the recorder with a voice starting recording function of built-in [ commercial ], and prolonged automatic recording is made.
Directions
  • An attached antenna is put in the antenna terminal of the front of a main part. Subsequently, an earphone is put in a front jack. And if a few front volume knobs are turned to the right, there will be sound. Now, it will be in a receivable state.
  • Subsequently, a front volume regulation knob is turned until it becomes suitable volume. No sound can be heard, if the electric wave is not sent or the channel is not correct.
  • The change switch of a channel is in the rear. The channel of a transmitter is suited in the place of the sign of A and B. When using an earphone, it puts in the hole by the side of it, and uses for it.
  • When carrying out automatic recording combining the transmitter for a telephone or a sound starting hearing transmitter, and the recorder with a commercial voice starting recording function, 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.

  • When the electric wave is not sending when hearing it by the earphone, or the channel is not correct, no sound can be heard even if it turns a volume knob. Since a sound powerful at a stretch will go into an ear and will hurt its ear when sound is received if it keeps turned, be careful.
