HEAD REPLACEMENT
NOTE: Heads can be replaced individually or as a complete assembly.
Azimuth adjustment (electronic) is not to be performed until all
mechanical alignments have been performed. After replacing the heads,
proceed to the next page for mechanical alignment.
CAUTION: All power must be removed from the unit when replacing
heads to prevent transient pulses from passing through the heads.
These may cause strong magnetization of the head material or damage
the delicate winding.
HEAD ASSEMBLY REPLACEMENT
~ Remove the head housing cover by loosening
two hex screws on top of cover.
~ Remove the four mounting screws indicated by
the arrows in the. diagram.
~ Slide the assy out from the plug.
- Fit the original shielding plate onto the new
head assy.
- Slide the new assembly onto the unit and se-
cure the four screws.
- Proceed to the next page for mechanical align-
ment procedures.
INDIVIDUAL HEAD REPLACEMENT
NOTE: All of the heads are individually
mounted on the top base plates of head
assembly for easy accessibility and
servicing.
- Remove head housing cover to expose head assy.
~ To replace a single head, a special 2mm nut
driver is required.
~- Remove the two nuts on the defective head
through the, access hole provided to release
the head from the mounting plate.
- Note the position of the head's wires on the
circuit board and unsolder the defective head.
- Using figure for reference, connect the new
head to the circuit board.
- Head installation mounting provides for either
left or right positioning.
- Determine the proper position by adjusting the
nuts to obtain a 90° angle between the tape
and the head.
