This system has been designed for translation, training or lectures in environments with high noise levels as well as traditional group tours.

The universal nature and mobility are the 2 biggest advantages of the Okayo systems. The Okayo EJ-7 is an ideal solution for companies that:

  • have their own conference room in which they need to ensure comfort for interpreters and speakers, as well as convenient listening for participants of international meetings
  • travel to conferences, fairs and other events with their own interpreter or guide – the EJ-7 mobile translation set ensures participants voice contact with the interpreter or guide
  • guide delegations or organise training on production lines, where noise prevents normal communication
  • The Okayo EJ-7 is a basic tool for translation agencies, travel agencies, guides, tour guides, trainers and training companies

The mobile, Okayo EJ-7 basic set can easily be expanded into a complete stationary system for simultaneous interpretation.

Features of the EJ-7 system:

  • runs on UHF band 863-865 MHz
  • 16 channels (frequencies) to choose from, PLL synthesis
  • one-way transmission (transmitter – receiver)
  • option to use 4 channels simultaneously – up to 4 transmitters can be used within a radius of 200 metres (on different channels) without interference
  • LCD display showing the channel number, frequency and battery level
  • simple switching of reception channel on EJ-7R
  • the EJ-7R receiver has an additional AUX output enabling connection with an additional device (e.g. an active speaker)
  • the EJ-7R transmitter has an additional AUX input enabling connection to an additional source (e.g. MP3 or CD player)
  • the devices run on standard rechargeable AA batteries, so it is possible to replace them with normal alkaline batteries
  • the runtime of fully charged batteries is up to 14h, while the runtime of alkaline batteries is up to 17h
  • battery charging time – up to 6h
  • range of 60-120 metres
  • metal, designer housing, resistant to mechanical damage
  • wide range of supplementary devices, including chargers, microphones and headphones
