[. . . ] Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding- type plug has two blades and a third grounding prong. [. . . ] Failure to properly set up the tone arm assembly can cause damage to the cartridge stylus and/or records. (Note: Once the tone arm locking clamp has been released, take extreme care not to damage the stylus. Do not allow it to drag or scrape across the slip mat. Remove the protective stylus cover guard. While gently holding the headshell to stabilize the tone arm, release the tone arm locking clamp. At this point, the tone arm is unbalanced and free to swing. Figure 3 – Headshell Assembling the Turntable Platter and Slip Mat 1. Carefully place the turntable platter on the center spindle, making certain the platter is fully seated on the spindle. Place the soft black slip mat on top of the platter. figure 4 – Platter and Slip Mat 4 Initial Setup (continued) 5. While gently holding the headshell, carefully rotate the counterweight until the tone arm is horizontally balanced and hovers freely just above the platter without touching the platter surface. Lock the tone arm back into the tone arm rest. While holding the counterweight steady, and without any rotation, carefully rotate only the black stylus force gauge ring (which turns independently of the counterweight) until the “0” on the gauge ring lines up with the centerline marked along the top of the rear arm. Refer to the cartridge manufacturer’s specifications for recommended tracking force. Rotate the entire counter-weight counterclockwise without touching the black gauge ring, moving the counterweight forward, until the desired value on gauge ring lines up with the centerline marked on the rear arm. It may also be used to connect the turntable’s RCA output to other equipment, including: • a stereo/boombox equipped with a 3. To use either adapter cable, connect the turntable’s red and white RCA plugs to the cable adapter’s RCA jacks. Note: If connection is desired to a mono amplifier/speaker, make certain to use a stereo-to-mono adapter, available from your dealer or an electronic parts store. Inserting a mono plug in the stereo jack will disable one of the stereo channels. Other adapter cable configurations will be available from dealers and parts stores for connecting to devices needing different terminations. Connecting AC Power Cord Finally, after all other connections are made, attach the included AC power cord to the turntable; note that the small connector only goes in one way. Then connect the power cord’s plug to a convenient AC outlet. [. . . ] The tracking force is set too heavy (stylus assembly is bottoming out on record). If the LED next to the pitch adjust slider center detent position remains blue when the slider is moved, quartz lock is engaged. Depress the quartz button to disengage the quartz lock and activate variable pitch. Strobe dots are difficult to see and/or stylus illuminator is very dim. [. . . ]
