The maximum presettable level may be so high as +7.1dB, which means 170kHz deviation: in this
case there is no difference with the limiter on or off. It is wise to not frequently trespass the limiter
threshold with the modulation or a heavy audible distortion may occur.
Field #27: Transmission Mode, and Pre-emphasis setup
Here it is possible to setup the transmission "modes" (MONO R, STEREO, MONO L+R, EXT
MPX), and the pre-emphasis time-constant (0, 25, 50 & 75
µ
s).
Everywhere in Europe and in most other countries, the standard pre-emphasis is 50
µ
s. In the
USA and in Latin American countries is 75
µ
s. Be sure to setup to the correct standard for your
area. The pre-emphasis is active only on the audio channels and do not acts on external multiplex
signal.
Field #29: Display contrast setup
From here it is possible to vary the display contrast to permit the best reading in different
environment situation or to compensate variation with components, temperature and aging. A
number 0 to 7 shows the preset level.
Field #30: Time & date setup
This field permits to edit either date and time
