1) Store or use where there is no any force causing transformation or change in quality;
2) Store or use where there is no any corrosive gas or sea (with salt) breeze;
3) Store or use under low humidity;
4) Solder the lead pin within the condition of ratings, After soldering, do not add outside force;
5) Do not wash this device, to prevent static electricity damage to the pre-amp, make sure that the human body, the soldering iron are connected to ground before using.
6) Please pay careful attention to the lens of receivers. It might have a chance to become abnormal when the lens gets dust or dirt, and also please do not touch the lens. |
