The Eliztech website has universal remote control codes for Apex TVs. The codes are 1236, 1241, 1287 and 1376. In order for a universal remote to communicate with an Apex TV, one of these codes must be entered into the remote.
Every universal remote has a slightly different procedure to connect the remote to the specific device. Typically, users must start by holding down the key that corresponds to the device being programmed, which can be a television, video cassette recorder, Blu-ray, DVD player or satellite. While holding the key, the user must punch in the code for the device being programmed. As the code is being punched in, the on/off light on the remote should turn off.
If the code is correct, the on/off light should come back on as the final number in the code is being hit. If this light does not turn back on but rather blinks a few times, that generally indicates that the code is not correct, and the remote control won't work.
Most universal remotes have an automatic code-searching feature. Searching for the code with this feature can take a lot longer, but this is another effective way to program a universal remote control to a TV.
