Ferrite Choke Installation Instructions

Document Number 3825-A2-GK40-10

November 1996

Overview

This document describes the procedure for installing a ferrite choke onto an RS-232 (V.24) cable. This is the cable

that connects your modem to a PC or other Data Terminal Equipment (DTE). To ensure compliance with FCC

Part 15 Regulations, a ferrite choke must be installed on the DTE cable.

Installation

Use the following procedure to install the ferrite choke.

1. Locate the end of the DTE cable that attaches to your modem. Open the ferrite choke and place it around

the cable as close to the cable connector as possible.

2. Close the two halves around the cable and snap the choke shut, pressing down on the plastic latch to

secure it in place.

3. Add a tie wrap as shown to prevent the ferrite chokes from slipping down the cable.
