1.0 Introduction
40-6680 5 beam laser pointer is a highly accurate instrument. Out side of a few
customer adjustments (outlined in the owners manual), all adjustments/service
operations are internal to the instrument and to be performed only by authorized
service personnel. Authorized personnel should adhere to the guidelines
described within this service manual for all repairs and/or service work. This
manual is written with the assumption that a unit is disassembled or assembled

replaced during a repair. Given this, procedures discussed in this manual should
be adjusted according to the repair being made.
