You can try contacting the manufacture via there web site www.aftron.com. The company is based in Dubai. I have tried to contact them via the website and via e-mail but have had no response.
Otherwise you can try finding another one on e-bay that doesn't work - I have seen them go very cheaply (£6) so you could just get the spare parts you needs and scrap the rest.
re: ---> Sorry, I can't help you with this, but I wonder if you can help me. I have an Aftron AFWK3370, but no user manual. Every time I switch it on, it runs for about 10 minutes then shows an error code (E8) and sounds an alarm. Do you know how to fix this problem?
I have the same problem. Did you ever manage to resolve this ? If so what did you do ?
