To program your Bose CineMate home theater system with the Spectrum remote, you will need to use the appropriate remote control codes. These rules vary depending on the model of your Spectrum remote and the specific model of Bose CineMate you have. Follow these detailed steps to program your Spectrum remote to control your Bose CineMate: Find the remote control code: First, you need to find the remote control code for your Bose CineMate system. Spectrum provides a list of remote control codes for devices on their website or in the remote control user manual. You can also try looking up specific codes online using the model number of your Spectrum remote and Bose CineMate. Turn on Bose CineMate: Ensure that your Bose CineMate system is turned on and in the proper mode for operation (e.g., TV or AUX mode). Enter programming mode: Press and hold the "Setup" button on your Spectrum remote until the LED indicator on the top of the remote turns on. Enter Code: Use the number buttons on the remote to enter the four-digit remote control code of your Bose CineMate. The LED indicator blinks to confirm the entered code. Test control: After entering the code, point the Spectrum remote at the Bose CineMate system and press various buttons (e.g., volume up/down, power) to see if it controls your Bose system. If it works, the program succeeds. Save the code: When the remote control works with your Bose CineMate, press the "Setup" button again to exit the programming mode. Now that the code is saved, your Spectrum remote should be able to control your Bose CineMate. Please note that not all remote control codes may work with all models of the Bose CineMate.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" to your device; in the "Search box at the top right of the display window" to get gathered related posts.

wharfdale TVs are rebadged by Argos, so I am unsure of the actual manufacturer, and therefore the control signal scheme that they use.
It might help if you gave the model number of the particular TV, as they could be using several different manufacturers in their range of televisions.
it is unlikely there will be a single code that covers the whole range of Wharfdale Tvs
