Possible causes
Solution
Power-on
problem
No display after press
the button
Not well load with the batteries or no
electricity or not well insert with adapter or
plug.
Check if the batteries have been load
with the wrong connection, if well
connection with batteries; Replace
new batteries; Check the power
supply with the adapter
there is something wrong with the electric
components of power on PCB,
crystal-oscillator or IC
Replace with new PCB
Key button not work
Replace with new key button
Display irregular
character after press
button
there is something wrong with the
crystal-oscillator on PCB, or MCU not well
insert
Replace the crystal-oscillator; well
insert the MCU.

Something wrong with the keys, or faulty PCB
board
Check the key button; Replace the
PCB
