8. Removethelower and upperarmcovers (pos.4/ Fig.1).
The capacitor bank might still contain up to 350 VDC.
Life-threatening hazard of electric shock.
Follow the safety procedures described in the docu-
ment Service Instructions for detailed instructions on
how to ensure the capacitor bank is discharged.
For MOBILETTs with remote exposure switch system
installed:
When removing the lower arm cover, be sure to unplug
the module connector for the remote control from the
electronics package alongside the main MOBILETT
CPU board (see pos. 1 / Fig. 18). Dismount the IR sen-
sor from the lower arm cover.
Remember how the cable was attached for future steps
