SECTION THREE : OPERATION
Once installed and set up as described in Section Two, no manual operation is provided apart from
selecting the required meter display. If the SYS NORMAL LED shows red, step through the various
displays, using the push button, to determine which do not show ‘Normal’.
Note, that for output
power to be generated, the Amplifier’s rear panel Interlock input, SK02, pins 20-21, must be
short circuited, either directly, or by the closing of all connected interlock circuits (see section
2.2.2).
The SYS NORMAL and MUTE LEDs will show red and it will be so indicated, on the Fwd and
Rev Power screens, if the Interlock is open and the Amplifier thus muted.
