fhiew Solder in this order: 220 – 220 ohm resistors (red-red-brown-gold); or you may have 200 ohm (red-black-brown-gold); or 250 ohm (red-blue-brown-gold). Any will work. 1k – 1000 ohm resistor (brown-black-red-gold). 10k – 10,000 ohm resistors (brown-black-orange-gold). Y1 – Crystal Oscillator - small silver tube. GRTV – 4-pin header: place near the top left of the PCB. Bend the pins upwards 20° to fit hole in the case. C1, C2: capacitors, small red disc. C3: capacitor, larger yellow disc. IC Sockets, 28 pin and 8 pin. Battery holder. DC: power socket. S1, S2: push switches. SW1: slide switch. Buzzer: Round plastic cylinder, 2 pins. Q1 - Q5: Transistors (black, 3 pins). GM: (Photoresistor or LDR light dependent resistor) – has zig zag line. (above the battery, about .5cm above the board) RM: Thermistor - the glass one. Middle of the top edge. It should sit a bit less than 1cm above the board. ***Check everything before adding the LED displays.*** Solder Digits 3 and 4 upside down. Check fit of the displays: I had to file some of the feet slightly.Attach adhesive diffuser. If you don't have one, use car window tinting or black plastic cut from the inside of a plastic mail order courier envelope.Insert ICs and battery.Case: do the rear first.Setting Time, Date, Alarm and Brightness:Lower button: parameter select. Top button: Show date or increase by 1.The parameters:Min; Hour; Alarm min; Alarm h; Alarm on/off (0000 or 1111); Month; Date; Day of week
