Voltage Regulators
The voltage regulators are polarized and
must be mounted so that their tabs correspond to
the tab markings on the circuit board graphics.
Solder all three leads and clip any excess off
flush with the solder joint.

LEDs
LEDs are polarized by the flat in the collar at the base
of part. When properly installed, this flat will align with
the corresponding flat in the LED symbol printed on
the circuit board.
When the 9730 is installed behind its front panel, the
LED will engage the hole in the front panel and be
supported by its leads. Install the LED by pushing it's
two leads through the holes in the circuit board. With
3/8" of space between the bottom of the LED and the
circuit board, solder one lead. Check spacing and polarization
before soldering the second lead and trimming both leads
off flush with the solder joint.

"Flying" Wires
(i.e. those which go from circuit board to panel mounted parts.)
In the following steps, wires will be soldered to the 9730 board
which in later steps will be connected to the front panel controls
and switches. At each step, cut a piece of wire to the specified
length and strip 1/4" of insulation from each end. Twist the
exposed wire strands together and "tin" them by melting a small
amount of solder into the strands. This will make soldering easier
when the wires are installed and prevents fraying
of the wire strands when they are pushed through
the holes. Solder each connection as it is made
and clip any excess wire from the solder side
of the board.
Leave about 3/8" space
between the circuit
board and LED base.
Note Tab
Note:
If you also have the
9710frm FracRak
Accessory kit do not use
the wire from that kit in
these steps. 9710frm
wires are already cut to
length for use with the
power connector.
