13. CHOKE COIL INSTALLATION
Caution: Leave the following work to a qualified service technician.
Be sure to switch off the power before the work.
If a checkbox for the indication of "The choke coil is installed." on the rear panel of the VM amplifier is marked with "X", this represents that the choke coil has been installed. Therefore, the following tasks are not necessary. When you installed the choke coil, mark the checkbox with "X".
To suppress harmonic component radiation from the power line of the unit, install the optional Chock Coil CT- 200M.
Note: In the countries where use of the CE Marking conformity is obligated, the Choke Coil must be installed.
Step 1. Remove 4 screws on the amplifier rear panel and a total of 6 screws on the sides to remove the cover.
Side: M4 x 8 machine screw | 3 pieces each |
Rear: M3 x 6 machine screw and M3 plain washer | 4 pieces |
