terminals, ensure the tab ‘clicks’ back down to lock the crimped wire
in the connector – a gentle tug on the wire will reveal whether the
crimp has been securely reinserted in the connector.
3. Remove the lens tube locking rings using the focus tool(s) pro-
vided (see fig. 1.2). Rotate the
TA
input and output lenses counter-
clockwise to pull the lenses away from the diode, taking note of
approximately how many rotations you make. Four full rotations
should be sufficient for the lenses to be well clear of the copper
mount.
4. Referring to fig. 8.4, remove the 4x screws securing the H-clamp on
top of the U-chassis. Gently slide the
MGM-068
mount upwards for
removal and pause if any resistance is met. The copper block will be
tight but should move when wiggled. Take care that the collimation
lenses are retracted (see above) so that they do not obstruct the
MGM-068
mount. Note that registration dowel pins prevent the
MGM-
