PLEASE READ THIS SECTION CAREFULLY, IF YOU ARE
USING ONE OF OUR CASES.
VISIO AND PRISMA CASE:
For our Visio and Prisma cases, mount all these components on the
top (tube) side of the PCB as shown below.
The longer lead on the LEDs goes in the hole .
STAINLESS STEEL CASE:
Solder the two jack sockets and four switches on the BOTTOM of
the PCB (non-tube side). Do not solder the three LEDs at this
stage. This is covered in the guide to the Stainless Steel Case.
To solder the GPS / RFT and PIR connectors: First wet one pad on
the PCB with solder. Then place the connector in position and re-
touch the pad with the soldering iron. This will anchor the
component and then you can solder the remaining pads.
4.15 LS1 (Piezo Buzzer)
The Piezo Buzzer is soldered on the bottom of the PCB.
