ADJUSTMENTS AND CALIBRATIONS
Meters - are to broadcast specification and either a VU or a PPM may be selected.
A choice of 3 scales is available for the PPM: BBC, N10, SDR.
Line-up-tone oscillator - the preset (VR4) that adjusts its level at the outputs of the
mixer is mounted on the right-hand PCB of the output module and can be adjusted
from the copper foil side of the board. (Refer to FIG 13)
Low-battery indicator - the preset (VR3) associated with this facility is mounted on the
right-hand PCB of the output module. The low reading is set at the factory and
corresponds to a set of batteries having discharged to 10v. On a VU meter, low volts
is at 0VU. On a PPM meter it is indicated by a separate marking: yellow on a BBC
scale and red on an N10 and SDR scale. (Refer to FIG 13)
