Display Color Control (Three-color Model Only)
• Short-circuit the R (J8) terminals with a short-circuit socket so that the display will be lit in red.
• Short-circuit the G (J10) terminals with a short-circuit socket so that the display will be lit in
• Short-circuit the R (J8) as well as G (J10) terminals with two short-circuit sockets so that the
