2 1. Before soldering check components against the part list to make sure you have correct kit contents and part quantities/values by the photo at right and part list in page2 and page 3. Report missing or wrong parts to your values are easy to mis-read. It is strongly suggested to check their valuesby ohm-meter before soldering them to sure you understand the polarities and orientations of all parts. 23 Before you startIf your have purchased 15002K kit (SMD not pre-soldered) you must install allSMD parts before mounting the through-hole parts. Please refer to the instructionsbelow for SMD part installation. Otherwise, proceed to page2 to start through-holepart assembly. Important !!!SMD parts are only installed to the analog board (PCB PN# 109-15001-xxx).U6179L05, SOT89 See page 2 fortools neededApplicable firmware version: 113-15001-061 or later(For PCB 109-15001-00F)Photos here are for illustration only.
