Important
If your kit does not have SMD
device pre-soldered you are
strongly suggested to install
all SMD parts before mounting
through-hole parts. Please see
instructions at Page 1.
Step 1
Assembly the Main Board (follow the order as numbered)
1. Check the main board
Before mounting any parts to the main board
1
connect a 9V power supply (center positive) to J7
on the board to check the display.
2
You should see the scope boots up to a screen
similar to the photo below. D1 (LED) blinks twice.
Do not solder any parts to the board if you find
problem. Otherwise warranty will be voided.
Report the problem to vender or JYE Tech.
2
Check
display
1
Apply power
(DC jack is 5.5mm dia.
with 2.1mm core)
2. Test Signal Terminal
J8
:
4.8 x 0.8mm terminal
Note:
Before soldering bend the terminal to the
shape as shown in the left photo above.
3. Power Connector (optional)
J6 0.1" pitch, rightangle

Tools you need
1
20 - 25W iron for most of parts. For the
BNC connector higher power iron (50 -
100W) is recommended if available.
2
Rosin solder wire (0.8 - 1mm dia.)
3
Digital multimeter
4
Screw driver (phillips, size# 0)
4. Slide Switch
SW5
5. Pin-header (male)
:
1X4 pin, 0.1" pitch
J2
6. Tact Switches
SW1, SW2,
SW3, SW4
7. Remove Resistor R30
Let iron stay on one pad of the resistor until solder on
the other pad melt and then remove the part.
Note:
R30 is used to bypass SW5 so as the mainboard can be
tested without the power switch. It must be removed
for correct functioning of the power switch.
Now apply power again. Test power switch
and tact buttons for their correct functions.
Flush cutter
5
Tweezers
6
DC 9V power supply with 200mA (or higher)
7
current capacity and 5.5 x 2.1mm plug.
8
Needle-nose pliers
Small slotted screwdriver (2mm width,

for cap trimmer adjustment)
Step 2
Assembly the Analog Board (follow the order as numbered)

Soldering Hints
1
Put leads through mounting holes from the side with
part outline. Ensue component evenly touch PCB.
Solder leads at the other side. Solder should fully
2
fill and cover soldering pads.
Avoid bridges between
neighbering pads.
3
Cut unused leads
flush with cutter.
4. Electrolytic capacitors
Note:
Always meter resistor
values before soldering.
Resistors are all 1/8W.
