3.3.3 On-Board LED indications
In addition to the LED indicators on the front display, other indicators are provided on the OWS main
control board as shown in Table 5. The status of the fault indicators is determined by the number of
flashes of each LED. The flash rate provides further indication of the fault type e.g. whether the wiring
fault in the speaker circuit is open or shot circuit, etc.
11 Available only in Brooks series of amplifiers to minimise the quiescent current.
