A. With a
ß
at-bladed pocket screwdriver, gently
pry the pushrod forward where it connects to
the power switch.
B. Gently lift the pushrod up, out of the power
switch.
C. Pull the pushrod back toward the AC line input
and out of the front panel.
3. Locate the three mounting screws and one nylon
stand-off which hold the power supply board to
the chassis.
4. Remove the three mounting screws. Note that the
two screws nearest the side panel of the chassis are
long screws which also fasten the digital board to
the chassis.
5. Carefully pry the power supply board away from
the nylon stand-off using a non-metallic tool. With
gentle pressure, the power supply board will snap
free of the stand-off and can be removed.
6. Carefully lift the power supply board from the in-
strument.
Assembly note:
When reinstalling the power switch
pushrod, insert the pushrod through the front panel,
then connect it to the power switch. (See drawing 7001-
053 at the end of this section.) When viewed from the
front of the unit, ensure that the POWER button is in
the outer (OFF) position before continuing assembly.
Front panel removal
Removal of the front panel does not require removal of
any other boards. Refer to drawings 7001-054 Final
Chassis Assembly and 7001-040 Front Panel Assembly
at the end of this section.
The front panel unit is an assembly of the front panel
bezel, display board, and keyboard assembly. It is held
in position by two plastic tabs on each side of the front
panel unit which engage two metal studs located on
each side of the chassis. The display itself is connected
to the digital board through a 16-conductor ribbon ca-
ble which feeds through a rectangular hole in the front
bulkhead.
To remove the front panel unit:
1. First pull the ribbon cable termination from its re-
ceptacle on the digital board.
2. Gently pry open the plastic strain relief that holds
the ribbon cable.
3. Gently pry up on both plastic tabs which hold one
end of the front bezel to the chassis, and slide the
bezel forward slightly to free the tabs. Repeat this
procedure for the other side of the bezel.
CAUTION
Take care to lift the tabs only far
enough to free the bezel. Excess force
will break the tabs.
4. When the front bezel has been freed, remove the
front panel assembly with ribbon cable.
5. The front panel unit can be further disassembled to
remove the display board if necessary. Locate the
plastic retaining bar located at the bottom inside
edge of the bezel. Carefully pop the bar away from
the bezel. Afterward, the display board can be re-
moved from the bezel.
6. The keyboard pushbuttons can now be removed
from the front panel. These are installed as one or
two multi-key overlays. The overlays are captured
by wells located in the inside of the front panel.
BNC board removal
Removal of the BNC board requires that the power
switch pushrod
Þ
rst be removed. If necessary, refer
back to removal of the power supply (step 2). Also, re-
fer to drawing 7001-053 Chassis Assembly at the end of
this section.
To remove the BNC board:
1. Con
Þ
rm that the pushrod has been removed.
2. Disconnect the cable which connects the micro
DIN board to the BNC board.
3. Disconnect the AC power feed from the BNC
board.
4. Loosen and remove the nuts and washers which
fasten the two BNC connectors to the rear panel.
5. Slide the BNC board toward the front of the unit
until the board slot aligns with the chassis lance,
then lift the board free of the chassis.
Digital board removal
Before the digital board and shield can be removed, the
micro DIN board must be removed. Refer to the previ-
ous instructions for removing this item, and then pro-
ceed with the following steps. Also, refer to drawing
7001-052 Digital Board/Chassis Assembly at the end of
this section.
