OVERVIEW
Two ferrite chokes and cable ties are shipped with every Model 3811 modem. To ensure compliance with FCC
Part 15 Regulations, a ferrite coke must be installed on both the EIA-232-D interface cable and the RS-366-A
interface cable.
INSTALLATION
Use Figure 1 and the following procedures to install the ferrite chokes and cable ties on to the DTE interface
cables.
1. Open the ferrite choke and place it around one of the DTE cables as close as possible to the DTE
connector attached to the rear connector plate.
2. Close the two halves around the cable and snap the ferrite choke shut, pressing down on the plastic latch
to secure it.
3. Install a cable tie behind the ferrite choke to prevent it from sliding along the cable.
4. If a second DTE cable is attached to the rear connector plate, repeat Steps 1–3.
