The tone oscillator can be activated anytime during recording by setting the Tone: Record Lock
feature in the Setup Menu. Press the Tone key anytime to generate a tone signal. Please note that
when enabled, any slight press of the tone key will generate tone and override any program material

LCD Contrast & Backlight, LED Brightness
LCD contrast is setup menu controlled. From the factory the contrast is set to 50%, suitable for most
viewing conditions. Contrast can be increased or decreased.
The front panel key toggles the LCD and key backlight. Backlighting is suitable in low or no
ambient light situations.
LED brightness is continuously adjustable from low to high. Hold down the key, then turn the
Rotary Controller to change brightness levels. The brightness of all LED’s is adjusted. In stealth
mode (setup menu selected) the LEDs are toggled on and off with the LCD backlight key.
LCD Gain Display
By default, the 722 displays the set Bit Depth and Sampling Rate in the right-hand side of the Main
LCD Display. The gain level for inputs 1 and 2 temporarily override the Bit Depth and Sampling
Rate display while the input gain pots are in use. The LCD display can be set to always display gain
by selecting Gain Only in the Setup Menu option LCD: Gain Display.
Record Indication
The position of the A-time numbers and time code numbers can be exchanged in the setup menu.
When Big time code is selected in the menu the time code is displayed in the main numeric dis-
play. If time code is turned off A-time is shown as large numbers, even with Big time code set.
To provide for additional visual indication that recording is in process the big numerals can be set to
reverse contrast or to flash during record. This is menu-selected.

24-Hour Time Counter
24-Hour Time Counter Mode is primarily used to easily identify the time-of-day that an event oc-
curred during a recording. When the Setup Menu option Time Counter: Mode is set to 24h, the
722 displays a 24-hour time counter on the Main LCD Display. The value of this counter is derived
from the 722’s internal time-of-day clock.
Recorded files are stamped with the beginning record time in metadata. Although this is not true
time code, the files are stamped in the beginning time code fields with a fixed 30 frames per second
frame rate. Files recorded with 24-Hour Time Counter Mode will display the time that they were
recorded when played back from the 722. The Time Counter Mode is set to off at Factory Default.
