qualified technician to restore the product to its
normal operation.
•
If the product has been dropped or damaged in any
way.
•
When the product exhibits a distinct change in
performance — this indicates a need for service.
REPLACEMENT PARTS -- W hen replacement parts
are required, be sure the service technician has used
replacement parts specified by the manufacturer or
have the same characteristics as the original part.

1. Make sure that the cartridge is properly wired. Refer to the Cartridge Assembly section on page 9.
2. Check if the stylus is worn out.
3. Make sure that the cartridge is making a proper connection. If need be, remove the cartridge and
clean the contacts on the back with Isopropyl alcohol, and reinsert it.
4. Check if the selector switch on the mixer is set to "Line" instead of "Phono." If so, switch
the selector switch to "Phono." Always connect the turntable RCA cord to the Phone input on a
mixer.
5. Check the RCA cables, are they connected properly? When the RCA cables are frequently
connected and disconnected, they may become damaged and need to be replaced.
6. Check the ground connection. Make sure it is not loose.
The sound level is very low:
1. Is the turntable connected to a device with a PHONO preamp. Connect the turntable to a preamp
mixer that has a PHONO input. Make sure the turntable is connected to the PHONO input, NOT
AUX or LINE.
The turntable skips consistantly:
1. Is the turntable on a unstable surface. Refer to Turntable Installation on page 11.
2. Check if the tone arm is balanced properly. Refer to Tone arm Balance and Stylus Pressure on
page 11.
3. Check if the stylus is worn out.
4. Check your records, are they warped?
