4.3.2 Final Alignment Using Telescope
Final alignment of ELDS OPGDs can be performed by a single technician using the following
equipment:

Alignment Telescope (see APPENDIX B, section 11)

2×M6 hex (Allen) key
CAUTION
The alignment telescope is a precision optical alignment device. Dropping or mishandling of the
alignment telescope may result in the telescope becoming incorrectly aligned.
If you DROP or DAMAGE an alignment telescope STOP using it; and either CHECK that the
alignment is still good using the process described in section 4.3.2, or RETURN it to Senscient
for checking and re-alignment.
Notes :

Ideally, final alignment should be performed on a clear, dry day.

Get familiar with the workings of the adjustable parts of the mounting bracket before
proceeding with the alignment procedure (See section 2.4).

To ensure precise field alignment, the alignment telescope makes use of the same mounting
datum that was used when the unit was aligned in the factory.

The telescope incorporates eye relief adjustment for comfortable viewing. The eyepiece should
be rotated to focus the image.

Keep the telescope and prism optics clean.

Do NOT try to adjust the cross-hairs using the telescope's elevation and windage adjusters.
These were precisely set in the factory and CANNOT be adjusted to this precision in field
conditions.

If the telescope is damaged or misaligned it will need to be returned to the factory for repair
and/or realignment.
