Contacta STS-K001L-B, STS-K001L-G User guide

  • Hello! I've analyzed the Installation & User Guide for the Contacta Bridge Bar Kit STS-K001L window intercom system. This guide covers how to set up the system, including the microphones, bridge bar, and hearing loop components. The manual includes detailed instructions for installation and troubleshooting and adjustment of amplifier. I'm ready to answer any questions you might have about it.
  • What is the purpose of this window intercom system?
    Does this system provide assistance for hearing device wearers?
    Should a qualified engineer install the system?
    What is the purpose of the confidence LED?

2) Ensure induction loop connector is
wiredcorrectlyandrmlypluggedin.
I can’t hear
audio through
the induction
loop.
1) Induction loop or microphone is
disconnected.
2)Looptesterhasafault.
1 ) Check instructions for correct
connections and, if possible, check
the hearing device with a known
workinghearingloop.
2) Ensure loop tester has a new set
ofbatteries.
I can hear
interference
through

1) Unscreened or poorly earthed
third party equipment is being used
incloseproximity.
2)Internalvolumegainsettohigh.
3) Incorrect power supply being
used.
1)Switchoanythirdparty
equipment to identify the source of
interference.
2)Accesstheamplierengineers
