Selecting DVRS Mode
When a 'DVRS Enabled' TG / Channel is selected on the MSU, the User may enter the
'DVRS Control Mode' by pressing the assigned VRS button on the Control Head and
change the DVRS Mode / Channel / Status as described below:
Selecting DVRS Mode from the Control Head
To change the DVRS Mode:
Execute a Single Press of the assigned VRS Button / Softkey and observe the
display flashing.
Execute consecutive single VRS button presses to toggle the DVRS Mode until the
desired Mode appears on the Control Head Display.
Once the desired Mode is displayed discontinue pressing the VRS button and
observe the DVR 'Control Mode' time out. The DVR Control Timeout tone (long high-
pitched tone) will be heard in the MSU speaker and the display will stop flashing.
The last selected (i.e. last displayed on the Control Head) DVR Mode is in effect.
Strapped DVRS Mode
The DVRS Mode and Channel may be programmed to be 'Strapped' to the specific MSU
TG/Channel.
In this case, selecting a specific MSU TG / Channel on the Control Head would
automatically force the DVR to revert to a pre-programmed DVR Mode and/or Channel.
For example, selecting a DVR Enabled TG named 'DISPATCH' on the MSU may
automatically force the DVR to switch to DVR Channel 1, SYSTEM Mode.
If enabled in the specific DVR personality programming, the DVRS User can still toggle
the DVR Mode by pressing the VRS Button and entering the 'DVR Control Mode'.
