1. Installation

1.1 Installation of the instrument panel.
1.     This instrument needs a hole of 92 x 92mm.
2.     Press the back of the instrument with the mounting bracket until the quick-fixed card lock the grooves on the two sides of the instrument.
3.     When removing the instrument, it is necessary to fix the instrument temporarily with adhesive tapes or hold the back of the instrument firmly in order to prevent the instrument from falling down. Pull the quick-fixed cards outwardly and draw out the instrument.
