2. Tin center conductor (DO NOT OVER TIN).
3. Solder contact to center conductor ensuring that dimension shown is maintained. Remove any
excess solder.
4. Clean housing area of outer conductor with abrasive paper and clean in a suitable agent.
5. Place connector assembly in Assembly Jig T1848, or other suitable clamping arrangement, with
contact in locator tool as shown.
Tighten screw to secure cable between inserts then tighten locator to seat cable firmly. Place
solder ring around cable adjacent to connector body and heat the connector body using an
appropriate heat source (solder tongs with variable control). Apply sufficient heat for solder to flow
but using minimum heat cycle.

6. Using dielectric insertion Tool T2508 (for plugs) or T2509 (for jacks), press insulator into body.
Assembly is now ready for use.
