Do not place the preamplifier where it could be exposed to dripping or splashing.
Do not remove or bypass the ground pin on the end of the AC cord. This may cause radio fre-
quency interference (RFI) to be introduced into your playback system.
The ventilation grids on the top and bottom of the preamplifier must be unobstructed at all
times during operation. Do not place flammable material on top of or beneath the component.
Turn off all systems’ power before connecting the preamplifier to any component.
Make sure all cable terminations are of the highest quality, free from frayed ends, short circuits,
or cold solder joints.
