WCT3  21
61. Install D1, a RED LED
62. Install D6, a RED LED
63. Install D7, a GREEN LED
64. Install D10, a GREEN LED
65. Install D8, a Yellow LED
66. Install S1 push button switch Make sure to seat the body flush to the
circuit board.
Locate the 9 volt battery snap clip. This is the black connector with a red and
black wire attached.
67. Trim the leads of the battery clip so they are 2.25 (two and a quarter,
2 1/4), inches long measured from the black cover.
68. Carefully strip about 1/8 inch of insulation form both the red and black
leads.
69. Insert and solder the red wire on the battery snap clip into the “BAT1”
“+” hole at the bottom left of the circuit board.
70. Insert and solder the black wire on the battery snap clip into the
“BAT1” “-” hole at the bottom left of the circuit board.
The next steps will install the pre-assembled antenna bundle for the
315/433MHZ, 125KHz and 20KHz signals. The heavy black rectangular box
in Figure 2 on page 22 represents the main antenna bundle and the 6 smaller
lines extending from the bundle are the individual antenna connections. There
are 5 cable ties holding the bundle together at the locations indicated by the
oval symbols. Take note of the ties indicated as “TR1”, “TR2” and “TR3” in
the following steps. Be careful not to deform the bundle as overall perform-
ance of your WCT3 may be degraded.
71. Looking at the antenna bundle, identify the 2 wires exiting the bundle
on either side of cable tie “TR1”. Insert and solder these two wires at lo-
cations “A1” and “A2” as shown in Figure 2.
72. Identify the wire exiting the bundle just above cable tie “TR2”. Insert
and solder this wire at location “ANT2”.
73. Identify the remaining wire from the same side of the bundle. Insert
and solder this wire at location “ANT1”.
74. On the opposite side of the bundle insert and solder the wire exiting
just above cable tie “TR3” at location “ANT3”.
75. The remaining wire exiting from the upper right corner of the bundle is
inserted into location “A3” and soldered.
REMEMBER!! DO NOT CLEAN THE BOARD
