• Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when

working inside the indicator enclosure.

• This unit uses double pole/neutral fusing which could create

an electric shock hazard. Procedures

requiring work inside the indicator must be performed by qualified service personnel only.

for the 920i. The power outlet supplying the indicator
