INSTALLATION

We recommend that the user not install the fluid damping trough until you become

thoroughly familiar with the use and features of the ET-2, and feel completely comfortable using

the tonearm. You should know how to level the tonearm and set the tracking force before

installing the damping trough.

We believe that the damping trough can be installed on any turntable/ET-2 combination

without any performance limitation. If you have specific questions about any installation, feel free

to contact us. The air pump should be turned off during installation.
