Contacta STS-K070 User guide

  • Hello! I've reviewed the Installation and User Guide for the Contacta Window Intercom System STS-K070. This manual provides instructions on installing speaker pods, mouse microphones, and an optional hearing loop, and how to use the amplifier adjustments, including the Engineer's Mode. I’m here to answer your questions about this system and its features, such as its fault detection LEDs and adjustable audio settings.
  • What does the red LED on the front panel indicate?
    How can I return the amplifier to factory default settings?
    How do I enter the Engineer's Mode?

Symptom Possible Fault Action
There is no
power
detected
through the
amplifier (and
there is power
at the socket).
1) Power jack not plugged in or
faulty.
2)Plugfusehasblown.
3) Faultypowersupplyunit.
4)Faultyamplier.
1)Checkpowerjackisrmlyplugged

The red LED is
illuminated on

1) Constant red LED:
Staorcustomer/visitor
microphonefault.
2) Red LED comes on after speech:
Inductionloopfault.
1) Ensure microphone is wired
correctlyandrmlypluggedin. Try
alternative microphone to ensure
portisworking.
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
speakers
(buzzing /
whistling /
hissing).
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Engineer’s
Modetoadjusttheinternalsettings.
3) Ensure that our grounded power
supplyunitisconnected.
Amplifier goes
into feedback.
1)Internalvolumegainsettoohigh.
2) Microphone positioned too close
tospeaker.
1)AccesstheamplierEngineer’s
Modetoadjusttheinternalsettings.
2) Move the microphone to a
locationfurtherfromthespeaker.
