 the modular plug and cable are compatible
 the cable polarity is properly maintained
 the modular plug is properly crimped and assembled
CAUTION
Make sure that the modular plug shield is fully bottomed onto the body. With some cables containing shielded twisted pairs,
this is especially IMPORTANT to check.
1. Close the tool handles until the ratchet releases, then allow the handles to open FULLY.
2. Hold the tool so that the back is facing you. Insert the modular plug (including shield and cable) in the
crimping chamber until it bottoms. Refer to Figure 3.

NOTE
This tool terminates three areas of the modular plug. For proper alignment, make sure to apply forward pressure on the cable
while closing the tool handles.
4. Remove the modular plug from the tool, and make sure that the crimp requirements are met according
to the applicable application specification (refer to first paragraph of Section 4).
If necessary, adjust the tool ratchet according to Paragraph 5.1 to obtain the proper crimp height.
