SWITCHES AND JACKS: See Figure 3.
9
2.1
Install J1 (DC power jack).
9
2.2
Install SW1 (DIP switch).
9
2.3
Install J2 and J3 (1/8" phone jacks).
9
2.4
Install J5 and J6 (3-pin headers).
3
SEMICONDUCTORS: See Figure 4.
9
3.1
Install D1 (1N4000 diode).
9
3.2
Install U1 (LM2940T-5.0 voltage
regulator IC). Solder its three legs AND
heavy metal tab to the circuit board.
Note: The metal tab must be soldered
to the PCB. As an alternative, it can be
mounted with heat sink grease and
4-40 machine screw (not included).
9
3.3
Install PWR (LED) with the anode (long
lead) in the square pad. The LED must
be mounted elevated so that it pokes
through the hole in the top cover. We
recommend that you solder the LED
after the top cover is installed.

RF MODULE INSTALLATION: See Figure 5.
9
4.1
Install the AWM680RX module. The
pin side will be slightly raised above
the PCB and the RF input end must
be mounted flush. If the module does
not sit correctly on the PCB, per
Figure-5, then it may be necessary to
file its metal mounting tabs
Note: The SMA-RP connector is
shown in the photo for reference only.
Do NOT install it at this time.
