Operational Check

The operational check tests the communication link between the remote control and the DCT1800. The procedures verify the DCT1800 response to remote control commands. Table 3-1 lists the operational check procedures:

Table 3-1

To execute a cold initialization:

1Hold down any key on the remote control while disconnecting and reconnecting AC power to the DCT1800.

After booting up, the POWER LED on the DCT1800 front panel will flash.

2Within 3 seconds, press the 3 key on the remote control.

The POWER LED on the DCT1800 front panel flashes at a decreased rate.

3Within 3 seconds, press the 2 key on the remote control.

The POWER LED on the DCT1800 front panel flashes at an increased rate.

4Within 3 seconds, press the 8 key on the remote control to initiate the cold reset.

During the cold initialization procedure, if the appropriate remote control key is not pressed within the three-second time period, the procedure terminates and the DCT1800 resumes normal operation.
