Remove the Radius5 MkII from its protective bag and check that the voltage label
indicates the correct voltage range and frequency for your mains supply. If the

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 are
fitted together.
RADIUS5 MkII 4
Remove the Drive Belt and gently place it around the platter and then onto the
pulley. Note position 1 is for 33 rpm and position 2 is for 45 rpm. It is important to
check that your mains supply frequency corresponds to the frequency specified
on the Radius5 MkII mains input label.
NOTE:
The Main Bearing is already charged with correct type of 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 requires cleaning with a cotton bud and recharging with Roksan
supplied bearing oil every 6-12 months. Consult your Roksan appointed retailer/distributor or contact Roksan Audio
for any assistance.
Finally, for assembling and fitting of your tonearm and cartridge, refer to the
manufacturer's user manual
