3. Remove the protective solder-bridge from the pickup.
Open the circuit after short-circuiting it.
4. If installing a new pickup, write the new head current
into memory as shown on page 9.
Do this first after turning on the unit with NO disc and
while the unit is cold (within the first 3 minutes of power
ON), or the jitter reading will not be accurate for the new
pickup head.
5. Adjust the optical pickup tilt after removing the solder.
(Refer to page 23, Optical Pickup Tilt Adjustment.)
Remove the solder.
