1. Introduction
1-1. System
The remote is designed to easily and quickly connect Cotek SR-1600 Plus.
The LCD display is used for setting up the inverter, as well as displaying current
status or fault messages. Pressing buttons allows you to select a menu item or
to save a setting, once it is displayed on the LCD screen.
