The design of the Radius5 record player has many special features not found in
other similar turntables. Drive mechanism utilises a custom synchronous motor
fitted with a precision-machined solid aluminium alloy pulley. The main bearing
housing and spindle are custom designed and machined from solid brass and
solid stainless steel to extremely high precision to ensure ultra smooth running
and longevity. The platter is machined from solid Acrylic to very high accuracy
and ensures speed stability. Main bearing, Platter and Tone Arm are mounted
on the sub-plinth and three point de-coupled from the main-plinth to maximise
performance and minimise acoustic break through. The motor assembly is
mounted on the motor block and then onto the main-plinth and further de-
coupled to avoid motor noise break through. Tone Arm cable is rigidly fixed to
the main-plinth that acts as a mechanical ground and minimises interference
with the sub-plinth. The Radius5 has three custom made adjustable spike feet
to allow levelling and provide optimum coupling to the surface that it sits on.
Partnered with the NIMA tone arm, the Radius5 has unparalleled performance
in its class.

Remove the Radius5 from its protective bag and check that the voltage
label indicates the correct voltage range for your mains supply. If the
Radius5 is fitted with the NIMA tone arm, be extra careful not to damage
the arm while you are assembling the record player.
(If in any doubt, remove the tone arm.
Remove the Adjustable Spike Feet (x3) from the accessories bag and
carefully fit them to the bottom plinth. Initially screw them all the way as
the surface you intend to place the Radius5 on would normally be level.
These could be used later to level the Radius5 in its final position if
required.
Remove the Platter, with the record label recess upper most, carefully
locate its central hole over the main bearing spindle and gently lower it
until the two fit/mate together.
Remove the Drive Belt and gently place it around the platter and onto the
pulley. Note position 1 & 3 would provide 33 & 45 rpm for mains supplies
running at 60Hz (cycles) and position

NOTE:

The Main Bearing is already charged with correct type oil & grease and
it is important that the Main Bearing Spindle is not removed from the
bearing housing. This will disperse some of the oil and necessitate
charging the Main Bearing with oil again. The Main Bearing will require
cleaning with a cotton bud and recharging, with Roksan supplied
bearing oil, every two years. Consult your Roksan appointed
retailer/distributor or contact Roksan Audio for any assistance.
Finally, for assembling and fitting of your tone arm and cartridge, refer to
the manufacturer's user manual.
IMPORTANT:
The Radius5 is mains operated. DO NOT try to gain access to the
inside of this unit. Refer all servicing to your Roksan appointed
retailer/distributor or contact Roksan Audio.
