3800 SPEAKER PANEL, FEATURE NUMBER 3800-F1-011 Installation Instructions Document Number 3810-A2-GZ43-30 December 1999
OVERVIEW An optional speaker panel can be installed to provide audio monitoring of any COMSPHEREr Model 3811 modem installed in a COMSPHERE 3000 Series Carrier. The speaker can be mounted directly to the carrier in place of the blank cover panel or above or below the carrier if a shared diagnostic control panel (SDCP) is used.
INSTALLATION Check the speaker, speaker jack, and panel for physical damage. If there are signs of damage, report this immediately to your shipping representative and your service representative. If the carrier has a blank cover panel installed, use Figure 1 and begin at Step 1 of the following procedure. If the carrier has an SDCP installed, use Figure 2 and begin with Step 2 of the following procedure to mount the speaker panel to the cabinet’s front rails. 1. First move the blank cover panel. To install the speaker panel directly to the front of the carrier, use a small flathead screwdriver to tighten the panel’s four #6 captive screws. Use the same screw holes that held the blank cover in place. See Figure 1. Continue to Step 6. 2. To install the speaker to the cabinet’s front mounting rails, first determine if you want to mount the speaker panel above or below the carrier. Then, fasten one of the speaker panel mounting brackets to a front mounting rail with a #10 Phillips-head screw (supplied). See Figure 2. NOTE If your cabinet has unthreaded rails, first attach a speed nut to the rail hole you intend to use. Then, fasten a bracket to the mounting rail using a supplied #12 screw (the longer Phillips-head screw).
3. Verify that this is the position in which you want to mount the panel by holding the panel against the bracket and aligning the panel’s captive screws with the bracket’s screw post. (For appearance, you can adjust the bracket’s position to eliminate space between the speaker panel and carrier.) If necessary, loosen the bracket and make any necessary adjustments. 4. Fasten the second speaker panel bracket to the other mounting rail to match the first bracket’s position. 5. Once the brackets are installed, use a small flathead screwdriver to tighten the speaker panel’s four #6 captive screws to the mounting brackets. 6. After installing the speaker panel, verify that the speaker is working. Connect one end of the supplied coiled cable into the speaker panel’s jack labeled Spkr and the other end into any Model 3811’s speaker jack labeled Spkr.
