You must first contact us with the equipment details and the symptom, first ascertain what the symptoms are and then explain clearly the symptoms as this will enable the service engineer/installer to rectify the fault/faults your equipment may have developed or may have been developing.
Example: There are numerous clues that may aid the service engineer in diagnosing and repairing faulty or problematic equipment as will now be explained.
Example #2: If you had a Television set that was switching off at random you would say "The TV is working ok but sometimes it goes off with no picture and no sound", this is a much better report of a symptom than simply saying "It does not work" or "Don't know" as Most people say, you may also want to note if any indicator lights are on or flashing.
