GENESIS G40: Assembly Help File - Pictorial PHASE 2.

Phase 2. - locate component bag labeled Phase 2. Use four wire cutoffs to form jump wire and solder as per photo. Place the 4K7 resistor in slot marked '100K' and other resistors as labeled on PCB.

- solder ceramic and electrolytic caps.

-IC's are factory supplied with pins slightly bent outwards so before you can place an IC into PCB you would need to get them straight -place IC on a flat surface sideways then press gently the top row op pins down with help of flat metal object.

- your IC is now ready for insertion into PCB.

- ICs in DIP package like SN74HC04 have an orientation notch (or dot) on one end. This notch must be oriented same way as notch printed on PCB layout. (NOTE: the actual writing on PCB may or MAY NOT align with print on IC, it is the notch itself which denotes the correct orientation!). Pins are numbered counter-clockwise starting from pin 1 located next to notch or dot.

- Solder IC and quartz crystal. The correct quartz crystal for Genesis G40 is 28.188 MHz. -connect power supply as in Phase 1. -check voltage at pin 11 and 12 with volt meter. It should read +1.5V to +3.9V. Otherwise if the voltage is close to 0 or +5V then oscillator is not working. NOTE: "to chek voltage at pin 11" means to measure voltage between "ground" point [-] and pin 11 [+]

-Alternatively, if you have a 'big' HF radio, disconnect antenna and place G40 close to it. Tune around 28.185-28.192 MHz where you should be able to hear the oscillator. Phase 2. is now completed.
