As a hospital grade TV, each source input can be enabled or disabled individually. In order to use the HDMI 2 source, for example, you would first need a PDi programming remote control to access the setup menu so you can enable that source. Make sure you’re using PD108-420 (it’s black with a PDi logo on the front) and enter the setup menu. The programming remote control is different than a remote control given to patients.
For A-Series Wall TVs:
If the TV has image version 104 you’ll go to Setup > Features (Enter password) > Hospital Mode > Lock Input Source.
If you have the newer image version 108 or later, it can be done in the setup menu when selecting “Sources".
To navigate to the HDMI source on personal arm TVs, you can do this by pressing the TV AV or input button on your pillow speaker or remote control. If the "channel up or down to other sources" is ENABLED in the setup menu, you can go to the first channel in your line up and by channeling down, you can access your HDMI source. Similarly, go to the last channel in your lineup and channel up to your HDMI source.
