6 Troubleshooting
In this chapter a simple fault-finding guide is given.
This is intended to be used to remedy the conse-
quences of incorrect installation. If more serious faults
or problems arise the installer should contact a quali-
fied technician.
Actions
• Check that the mains supply to the transmitter is connected and that the
transmitter is switched on.
• Ensure that connections to all radiators have been made correctly and that
each radiator’s mains supply is connected and switched on.
• Ensure that connections to all radiators have been made correctly and that
each radiator’s mains supply is connected and switched on.
• Examine the radiator LEDs.
• Check that the optical network is connected correctly.
• Check that the control unit of the DCN Next Generation conference system
is switched on or disable the network mode (menu 4B).
• Enable the network mode (menu 4B) or disconnect the transmitter from the
optical network.
• Ensure that the number of channels is set to automatic (using menu item
4B).
• Check that the emergency contact is connected correctly.
• Check that the audio is connected according to the selected auxiliary input
mode (menu 4I).
• IRED panel is in temperature protection mode. Check that the natural air-
flow around that radiator is not obstructed. If not so, replace the radiator.
• IRED panel malfunctions and the radiator should be replaced.
• If disposable batteries are used, check whether the batteries have suffi-
cient capacity and whether they are inserted with the correct polarity.
• If a battery pack is used, ensure that the battery pack is fully charged.
• Ensure that the headphone is connected properly.
• Switch the receiver on and check whether the display indicates a channel.
• Ensure that the receiver picks up sufficient IR signal and check whether
the antenna symbol becomes visible.
• Enable the mini radiator (menu 4M) and check the receiver by holding it in
front of the mini radiator of the transmitter.
• Ensure that the volume control is turned up.
• Set the transmitter in test mode and check whether the test tone is audible
on the receiver.
• If the test tone is not audible, do the same test with other receivers.
If all receivers do not work properly at that spot, check the coverage of the
system (see section 1.6).
