Note: It is a best practice to set Volume1 at a value above zero. A zero volume level is
considered as a mute and when the user adjusts the volume up, some displays show the
status bar as if their volume is turned up, but the display remains muted.

Relative Volume Commands
To define relative volume controls for the attached TV:
1. On the Serial Commands tab for the desired TV type, click the + at the upper
right of the Available Serial Commands list box.
2. Click + at the upper right of the Available Serial Commands box and add a
corresponding command called VolumeUp.
3. Press Enter.
4. The VolumeUp will automatically be selected in the available list. Click << to add
it to the configured list.
5. Select the VolumeUp command in the configured list and click + at the upper
right of the Serial Strings of Selected Commands. Enter the appropriate RS-232
command to increase the volume.
command to increase the volume.
6. Press Enter.
7. Repeat steps 1 through 6 to define a command for VolumeDown.
8. Click Save.
Repeating Relative Volume Serial Commands
As previously mentioned, the VolumeUp and VolumeDown commands rely upon the
incremental volume settings that are internal to each model of TV. For some TVs,
the increase/decrease in volume is very slight, requiring multiple VolumeUp or
VolumeDown commands to achieve the desired effect. For these TVs, you can add
and define a serial command with the label “dmp.RelativeVolumeSteps.”

the increase/decrease in volume is very slight, requiring multiple VolumeUp or
VolumeDown commands to achieve the desired effect. For these TVs, you can add
and define a serial command with the label “dmp.RelativeVolumeSteps.”
The value that you specify for dmp.RelativeVolumeSteps represents the number of
times the RS-232 command for VolumeUp or VolumeDown will be repeated when
you press up or down on the IR remote (or on the phone). For example, if
dmp.RelativeVolumeSteps is set to 8, then a VolumeUp command will result in 8
copies of the up string being sent, rather than just one. If dmp.RelativeVolumeSteps
is not set, then the default value is 1.
