Installing Batteries in Remote Control
Before using the remote control, you must install two AA (1.5 V) alkaline batteries. Figure 2-4 illustrates battery access on the back of the remote control. To install batteries in a Motorola universal remote control:
Press and slide the battery compartment cover off. Place the batteries in the compartment; be careful to observe the correct polarity. Slide the battery compartment cover back into place.
Battery installation will vary with each style of remote control. Refer to the instructions included with your remote control for installing batteries.
Figure 2-4 Back view of remote control
NOTE! Use and dispose of batteries in accordance with all applicable laws, rules and regulations. Motorola will not be liable to anyone for the user's failure to use and/or dispose of batteries in the proper manner and in accordance with such laws, rules and regulations, or for any defect contained in batteries that may cause injury damage to persons or property.
This section provides instructions for installing and cabling the DCT1800. To complete the installation, you must: ! ! ! ! Connect the cables Supply power to equipment Download configuration information and software Run operational check and diagnostics
This section also includes the procedure for performing a cold initialization of the DCT1800.

Before You Begin

Before you begin, review the installation instructions, gather the required items, and complete the tasks listed below: ! ! ! Verify that you have 75-ohm coaxial cables with F-type connectors and RCA baseband phono-type cables. Determine if you are connecting the DCT1800 to a standard TV or a composite (baseband) monitor. Place the DCT1800 on a smooth, flat surface and remove any obstructions that could interfere with the free flow of air over, under, or around it. Advise the subscriber not to place anything on top of the unit.

Installing the DCT1800

To install the DCT1800:
Determine if you are connecting the DCT1800 to a conventional TV or to a monitor. To install the video connection: ! ! For a conventional TV, use a 75-ohm coaxial cable with F-type connectors. For a monitor, use an RCA phono cable to connect the VIDEO connector to the monitor.
Locate the cabling diagram that matches the subscribers configuration requirement. Connect the cables as illustrated in the diagram. Perform the basic operational check in this section after the DCT1800 is installed.

Standard Cabling Diagram

The DCT1800 will output on either channel 3 or 4 depending on the configuration message from the control system. Figure 3-1 illustrates a standard diagram connecting the DCT1800 to a TV using RF connectors:

Motorola DCT1800 Troubleshooting
Select the issue below that you are having with your set-top box and follow the steps to resolve:

No sound

Press Mute on the remote control to restore the volume level Check that the stereo is connected to the appropriate input source Turn on the VCR Make sure the TV or stereo volume is set to an appropriate level. For the best audio level control, use the remote control to set the set-top box to approximately of the maximum volume level and then adjust the audio levels for any of your other external devices.

No picture

Ensure that all cables are properly connected and if necessary, hand-tighten the connections. If your set-top box is connected through the baseband RCA video connection, make sure the cables are properly connected. If you are watching TV using your VCR, make sure your VCR is turned on and is running.
Picture or sound is noisy on one channel
Top Reconnect the cable and hand-tighten the connection if it is loose
Sound is only coming out of one speaker
Top Hand-tighten or reconnect the cables properly Make sure the wires are not frayed and plugs are not bent or broken

No power

Top Reconnect the power cord Make sure the set-top box is plugged into an outlet that works
Remote control does not work
Press CABLE on the remote control to ensure that the remote control is in cable mode Change the batteries in the remote control according to the instructions for the remote Make sure that nothing is on the set-top box or blocking the path between the remote control and the set-top box
