GETTING STARTED
INITIAL SETUP
1. Place the unit on a flat and level surface. The selected location should
be stable and free from vibration.
2. Install the turntable lid to the hinges.
3. Remove the tie-wrap that is holding the tonearm.
4. Put the drive belt around the Turntable Hub, and then use the provided
belt hoot to help pull the belt to fit around the slot of motor pulley.
5. Place the turntable platter through the turntable spindle.
6. Place the slip mat on top of the turntable platter.
7. Slide Tonearm Counterweight onto tonearm and twist it lightly onto the
rear shaft of the tonearm.
8. Adjust the counterweight to set proper stylus pressure.

assembly is completed. Before turning the power on, make sure again all
the connection setting are correct. Always turn off the power when
connecting or disconnecting.
CARTRIDGE DOWN FORCE ADJUSTMENT
The Counterweight supplied is suitable for cartridges weighing between
3.0-6.0g. Gently push and turn the Counterweight onto the rear of the
tonearm (with the scale facing toward the front of the turntable).
Remove the cartridge protection cap. Lower the tonearm lift and position
the cartridge in the space between tonearm rest and platter.Carefully
rotate the Counterweight until the tonearm balances out. The tonearm
should return to the balanced position if it is moved up or down.
This adjustment must be done carefully.
The anti-skating force must be adjusted corresponding to the tracking
force as follows:
Tracking Force
5-10 mN
10-15 mN
15-20 mN
20mN and bigger
1st from bearing ring
2nd from the bearing ring
3rd from the bearing ring
4th from the bearing ring
Groove in the stick
Once the tonearm is correctly balanced return it to its’ rest. Hold the
Counterweight without moving it, and gently rotate the Down force Scale
ring until the zero is in line with black line on the rear of the tonearm.
Check whether the arm still balances out.
Rotate the counterweight counter clockwise (seen from the front) to
adjust the down force according to the cartridge manufacturer’s recom-
mendations. One mark on the scale represents 0.05g of down force.
NOTE: The recommended down force for the factory fitted cartridge is
1.8-2.2g (Model: AT-VM95E)

cartridge being used. The factory installed cartridge is 47k ohms/MM-input.
NOTE: If your amplifier does not have an input suitable for phono cartridges,
you will need to purchase a separate phono amplifier for moving magnetic
cartidges. This separate phono amplifier will then connect between your
turntable and your amplifier.

CARTRIDGE REPLACEMENT
NOTE: Factory screw tightness is based on the thickness of the included
slip mat. If a thinner or thicker 3rd-party slip mat is used, gently adjust the
screw as needed following the steps in the last two situations.
5. Connect the wire leads to the new cartridge’s terminals. The wire lead
color are as below:
6. Adjust the cartridge’s position to make sure it is precisely aligned on
the headshell so that the stylus will be tracking the grooves in parallel
perfectly. To achieve this, place the included paper cartridge alignment
protractor over the turntable spindle, carefully lift the tone arm and
place the tip of the stylus on the points marked 130mm and 250mm
respectively. Fine tune the cartridge’s position on the headshell until
the cartridge is perfectly in parallel with the reference lines at both
posits.
7. Tighten the screws completely once the perfect alignment is achieved.
NOTE:
· Design and specifications are subject to change without notice.
1. Do not touch the stylus tip with your fingers. Avoid bumping the stylus
on the turntable mat or a record’s edge.
2. Clean the stylus frequently with a soft brush with a back-to-front
motion only.
3. Clean the records to get rid of dust or grease with a record cleaning
brush and record cleaning solution.
4. Clean the turntable lid and turntable cabinet with a slightly damped
microfiber cloth.

Your turntable requires little of no regular maintenance. Remove dust
with a slightly damp antistatic cloth. Never use a dry cloth, this will create
static electricity and attract more dust! Antistatic cleaning agents are
available at specialist stores, but must be applied sparingly to avoid
damage to rubber parts. It is recommended to install the needle cover
before cleaning or maintenance is carried out to avoid damage.
If the turntable is not used over a long period of time, the drive belt should
be removed to prevent unequal stretching.
NOTE: Always disconnect the record player from the power supply as a
precaution before maintenance!
USEFUL TIPS
The turntable should be positioned on a low-resonance surface such as
wood or multiple layer ply board to avoid structural vibrations disturbing
playback.
