Soldered-in Jumper Removal
Some plug-in locations have soldered-in jumpers next to a plug-in location. If an accessory will be
installed in any plug-in location that has a soldered-in jumper, the soldered-in jumper must first be
removed completely before installing the accessory.
➤ To remove a soldered-in jumper
1. Find the jumper wire in a plug-in location(PAD, EQ).
2. Use wire cutters to cut one end of the jumper.
3. Use needlenose pliers to grasp the jumper at the cut end.
4. While firmly grasping the jumper, use wire cutters to cut the remaining soldered end of the
jumper.
5. Remove the jumper with the needlenose pliers.
