1202-P-5816 Vantage + Service Manual

Introduction

This manual covers servicing of both the Bulb and LED illuminated versions.

All drawings refer to both Bulb and LED Module versions.

Service Principles

The Vantage + comprises a number of modules which have been built and
aligned in the factory. These modules can not be reliably aligned without the
special jigs and should not therefore be disassembled further than described
in this manual. There is a strong possibility of the unit developing diplopia or
hyperphoria if the Viewing Optics are disassembled or adjusted.
Where a sub-assembly is quoted it cannot normally be reliably repaired
without special tools, adhesive and/or jigs.

Precautions

Care should be taken to carry out any repair work on a clean soft surface to
minimise damage to the outside of the unit.
Solvents should not be used for cleaning.

Disassembly

Virtually all repairs inside the head unit except changing the Centre Mirror
involve removing both the Viewing Optics Assy and the Illumination Assy from
the Rear Cover. This involves removing the whole Optics Assy from the
Browbar.
