About the service it's very fast and reliable. About the manual the quality is high enough to read even the tiniest details on the wiring diagrams so you can't ask much more than that, let it alone for a manual of a product from 20 years ago. Thank you, very satisfied.
Everything was ok with the manual. If I have a small complaint, is that I ordered it during the weekend and I think you guys were closed. But I did receive it late Sunday. I will surely order from you again

(3) Blinking in red (Alarm of temperature error)
Since the internal temperature is too high in the product, the temperature protector has been actuated. In such a case, the following actions should be taken immediately: 1. Turn off the main power supply and pull out the power cord from the wall outlet. 2. Wait for about 60 minutes until the temperature in the main unit lowers. 3. Check whether the heat discharge port is covered with dust or the like. If yes, remove the clogging substance. 4. If the unit is used where the ambient temperature is high, it should be moved to an adequate place (air temperature ranging from 5Â°C to 35Â°C).
