2 Installation
•
The Hour Set button (the closest to the board
operator) adjusts the hour display
•
The Minute Set button (middle) adjusts the
minute display
•
The Hold button freezes the clock so it can be
manually synchronized to a local time refer-
ence. Set the time slightly ahead of the refer-
ence time then press Hold. Release Hold when
the time display matches the reference time.
NOTE:
When one of the master modes
is selected (see Clock Settings) and the
selected format signal (ESE or SMPTE)
is not present, the clock runs off its in-
ternal oscillator. Both display colons
blink to indicate the ESE or SMPTE
timecode is not present or valid.
The clock will keep time for about three days
with the console powered off. Beyond this point
the time will have to be reset again when autono-
mous mode is used.
Removing the Console Display
The console display must be removed from the
frame to change display settings, to connect a mas-
ter clock or remote timer reset cable or to install
the Quad Meter Package.
Each of these activities require accessing the
meter and clock-timer printed circuit assemblies
(PCAs) on the bottom of the console display. The
console should be powered off when removing and
reinstalling the display assembly. Two padded sur-
faces are required for this procedure. To remove
the console display:
1.
Flip-up the rear connector cover to access the
two rear corner 4-40 screws that hold the re-
flector in place. Remove these screws.
2.
Lift the reflector out of its slot. Place it on a
padded surface to protect its mirrored surface.
3.
Remove the console display cosmetic cover
screws (two or four 4-40 Phillips screws). Re-
move the cover by lifting it straight up.
4.
Set the smoked display window (which was
sandwiched between the display cover and the
main display subassembly) off to the side.
5.
Remove the display subassembly mounting
screws (4-40 Phillips) along the front of the
subassembly just above the control panels.
6.
To protect the control panels and display sub-
assembly, lay padded material over the top half
of the control panels. Lift the display subas-
sembly up just enough to clear the frame, flip
it forward and lay it facedown onto the pad-
ded material. The display subassembly con-
nects to the Monitor & Output board using
two cables. Do not strain these cables while
removing the subassembly and placing it onto
the control panels.
7.
Use the illustration on the next page to iden-
tify the switches and connectors on the clock-
timer and meter PCAs.
SAFETY NOTE:
Touch the metal chas-
sis to dissipate static before adjusting
the switches or plugging in an ESE,
SMPTE or remote timer cable. Do not
touch any components on the PCAs
other than the switches or connectors.
Reinstall the console display in reverse order. Use
care to not pinch any cables between metal parts.
Align the smoked display window holes with the
clock set holes. The cosmetic cover holds it in place.
