Trouble shooting:
If the IR Classmate does not operate as expected check the following:
Symptom
Probable cause/remedy
Main unit
No red indicator lights
Unit unplugged, switched off or fuse blown
Red indicators solid but no sound
Volume control too low, transmitter not on,
speaker cable disconnected
Red indicators flashing and no sound
Unit in charge mode
No green 'Signal' indicators
Transmitter unit not functioning ‒ check led
indicator on transmitter.
Microphone transmitters
‒ all types unless specified
No light on transmitter

Alternating green/red light on
Swift
TX
transmitter
Batteries need recharging
Red light on handheld transmitter
Batteries need recharging
Green light on transmitter
but no green light on wall unit
Receiver not receiving the IR signal.
‒ Check that microphone emitters are not covered
or pointing into non-reflective area.
‒ Check dome sensor is not obstructed and look for
red LED in centre. No red LED indicates no
connection between sensor and wall box so check
wiring on F-plug connectors.
No red light on infra red sensor
Coaxial cable connections faulty or internal fault
caused by short circuit
Distorted, whistling and generally
nasty sound
Two transmitters on the same channel will cause this
‒ turn one off. Has your colleague from next door
come in wearing their transmitter?
Feedback whistling all the time or
when the user of the transmitter speaks
‘Mic’ volume too high. Microphone too far away
from user's mouth.
Sound too bright or boomy
Adjust the tone controls to suit the acoustics of the
room and speakers
Sound distorted
Reduce the volume of the appropriate channel.
The system is only intended for speech and music
in an average size classroom giving up to
about 90dB SPL.

Handy hint:
You can easily check if the transmitter emitters are working by pointing a
mobile phone camera at them ‒ you don’t need to take the photo but the emitters will
show up really clearly!
The camera will see the infra red light from the emitters.
Do not allow the door to swing open ‒ either use it shut or fully open, to
reduce the probability of someone hitting their head on it.
The unit will become warm during normal use.
The inside front panel will become hot when the system is producing continuous loud
sound.
Open the door if the unit is to be used for extended periods (i.e. more than ten
minutes) with loud or continuous sound such as music or if the ambient temperature
is above 30
°
C.
Do not block the ventilation holes at the bottom and top of the unit.
Do not allow the tip of the charger lead to touch any metallic object, including the
casework of the IR Classmate. Store the charger plug safely in the insulated door pouch
when not in use or remove from the front panel socket.
The charger in the IR Classmate is designed only to charge Connevans infra red
transmitters which contain Ni-MH batteries of 2800mAh capacity. Do not attempt to
charge other devices, battery types or use for other purposes.
Do not use non-rechargeable batteries in IR Classmate transmitters as this may cause
damage.
Do not expose the IR Classmate to rain or moisture.
Do not fit in direct sunlight or over a heater.
The IR Classmate wall unit MUST be earthed.
For continued protection, replace the fuse only with the same type and rating i.e.
Antisurge T630mA.
Hazardous voltages exist inside the IR Classmate unit.
No user serviceable parts inside.
Refer servicing to authorised representatives of Connevans Limited.
Remove the mains plug from the wall socket before undertaking any servicing
operations.
