ronment.

Time and Date
(Menu Screen 20)
This screen presents the time and date that is embedded in
the transmission, plus the offset from Universal Coordinat-
ed Time (UTC) at the transmission location. The INOmini
661 does not correct the display to show local time if the
reception location is in a different time zone.
HIDDEN MENUS
The INOmini 661 also has settings for little-used, set-and-
forget functions. On an exclusive need-to-know basis, hold-
down the knob for a few seconds to access this top-secret
area.
Firmware Version
(Hidden Menu Screen 1)
The
661 Firmware
screen will apprise you of what firm-
ware version is installed in your unit.
Alarm Polarity
(Hidden Menu Screen 2)
When an alarm is triggered, the rear-panel ‘tally’ outputs
can take the form of either a closure to ground or a fulltime
ground that goes open-circuit for the alarm.
Push the knob and
D
(Digital Loss Alarm) will
begin blinking. Turn the
knob to select
G
, a
ground for the alarm or
O
, an open circuit from a normally-grounded condition.
Push the knob to save the setting, which will take you to a
blinking
L
(Low Signal). Make your selection, push the knob
and do the same for A (Audio Loss). Push the knob a final
time to save settings and release the menu.
In the example above, the rear-panel
D
and
L
terminals will
give closures to ground for their associated alarms, and the
A
terminal will be grounded and go open-circuit for Audio
Loss.
Backlight Color
(Hidden Menu Screen 3)
The INOmini 661 has a large, easy-to-read, backlit LCD dis-
play. A Digital Loss Alarm, Low Signal or Audio Loss condi-
tion will cause the display to flash the alarm notification
