There are nine codes (1-9), so you don't have to use codes 1 and 2.1. Prepare the DVRs. Cover the area around the shiny,
dark plastic window on the front of either DVR (call
this one DVR #2). You can use a dark piece of cloth or a magazineor anything else
thick and opaque. This prevents DVR #2 from receiving signals.
Point the remote control at the other DVR (DVR #1) and go to TiVo Central by
pressing the TiVo button. Select Messages & Setup, then System Information. Press
the DOWN arrow until you see the item Remote Address.
2. Prepare the remote control. Move the DVR SWITCH to 1, then point the remote
away from DVR #1 and cover the front end of the remote with your hand.
Press and hold the PAUSE and TiVo buttons simultaneously (for about 5 seconds)
until the red light at the end of the remote control comes on, remains steady, then stays
on when you release the buttons.
3. Assign side 1 on the DVR SWITCH to DVR #1. Point the remote control at DVR #1.
Use the number buttons on the remote control to enter a number 1. Press the RIGHT
arrow. On the screen, the Remote Address updates from 0 to 1.
Press the TiVo button and go to TiVo Central. Side 1 now controls DVR #1 only.
Continue to the next step and set up side 2 of the DVR SWITCH. If you dont, side 2
will still control both DVRs.
4. Prepare the DVRs again. Press the input, source, or TV/Video button you normally
use, until your TV displays DVR #2. Then remove the cover from the plastic window
of DVR #2 and cover the plastic window of DVR #1. Finally, go to the System
Information screen of DVR #2, and press DOWN arrow until you see Remote
Address displayed.
5. Assign side 2 on the DVR SWITCH to DVR #2. Move the DVR SWITCH to 2. Repeat
steps 2 and 3, above. Assign the number 2 to DVR #2, then press the TiVo button
and go to TiVo Central.
Now when you set the DVR SWITCH to 1, it will only control DVR #1and when
you set it to 2, it will only control DVR #2.
