RCA RCU400R3 - Manual (Page 15)

Special Operations
RCA, GE and PROSCAN Brand Devices:
Many of these devices (TVs and VCRs) do not need to be
programmed. In the event that programming is required,
the code search method is suggested.
Note: With these brands, the device button (TV, VCR)
will usually turn the units on. The OFF/ON button will
only turn these devices off.
SCIENTIFIC ATLANTIC Cable Boxes:
This brand of cable box can be programmed using the
code search method by using the CHANNEL UP key
rather than OFF/ON during Code Search. NOTE: The
device must be turned on prior to beginning the code
search. Once the device turns off, press and release
ENTER. In most cases this cable box can be turned on
and off using the CHANNEL UP key not the OFF/ON
button. If the unit will not turn on using the CHANNEL
UP key, then manually turn it on and only partial com­
patibility will be achieved.
JERROLD or GENERAL INSTRUMENTS Cable Boxes:
These units can be programmed using the code search
method. In some cases, these devices will change chan­
nels during the code search. Continue until the unit
turns off, then press and release
ENTER.
ZENITH and OAK Cable Boxes:
Some Zenith and Oak Cable Boxes require pressing
CHANNEL DOWN rather than ENTER after numeric entry.
Low Battery Warning:
When your batteries are weak, the device keys will light
sequentially indicating it is time to change batteries.
Remote Does Not Respond:
If remote does not respond or "locks up" and your
device does not respond to commands, remove the
batteries and press the number 1 on the keypad for
60 seconds. Then reinstall the batteries and reprogram
the remote for each of your devices.
