9.9 Receiver Setup menu
9.9.1 Screen #23: BF output level setting
From this screen, you may vary the levels of main BF outputs, "MPX" output and
"Mono" output at the same time. The screen shows nominal output level with 75kHz
incoming signal modulation and the level determined by current modulation. Variation
range of nominal output level is from -1.5 and +12dBm.
9.9.2 Screen #24: Useful Field level setting and Muting
This screen lets you edit the field threshold that energises the incoming useful field
internal relay and the audio muting function. Both functions use the same threshold,
however the muting function may also be enabled (ON) or disabled (OFF) from the
setup menu.
If the threshold is set to the lower limit (-99dBm), the function will not be triggered.
9.9.3 Screens #25 and #26: Deemphasis setting
From these two screens, you may choose among 0, 25, 50 and 75µs deemphasis
settings. Deemphasis may be enabled separately for the mono output and for the
stereo channel outputs, if fitted.
9.9.4 Screen #31: Optional internal board recognition
This screen lists any optional internal boards installed with no need for complicated
procedures. It saves the user the trouble to open the unit to establish whether any one
optional board is installed.
