Selecting VRX1000 Channel
When a ‘DVRS Enabled’ TG / Channel is selected on the MSU, the user may enter the
‘DVRS/VRX Control Mode’ by pressing the assigned DVRS button on the MSU control
head and then change the VRX1000 mode / channel / status as described below:
Independent VRX1000 Channel Change
To change the VRX1000 channel:
• Press the DVRS button and observe the display changing to the ‘DVR/VRX
Control Mode’ screen with the top line displaying the currently selected VRX1000
mode and channel.
• Use the MSU control head navigation keys to scroll through the available
VRX1000 channels. Once the desired VRX1000 channel is selected, press the
SEL button or wait until the control mode times out.
Strapped VRX1000 Channel Change
The VRX1000 mode and channel may be programmed to be strapped to the specific
MSU TG/channel. In this case, selecting a specific MSU TG / channel would
automatically force the VRX1000 to revert to a given VRX1000 channel and/or mode.
For example, selecting a VRX1000 Enabled TG named ‘DISPATCH’ on the MSU CH
may automatically force the VRX1000 to switch to Channel 1, SYSTEM Mode.
When strapping is enabled, and the VRX1000 channel follows the MSU TG/mode
selection, the user may still be allowed (if enabled by the VRX1000 programmed
personality) to change the VRX1000 channel by pressing the DVRS button and then
turning the mode knob.
Local Mode Indication
When the VRX1000 is operating in the LOCAL mode, the “DVRS/VRX Enabled” PSU
User can see “LOCAL ONLY” message displayed on the PSU screen if Status
broadcast is enabled in the VRX1000 as described in the ‘Status Broadcast’ paragraph.
The above indication is only available on ‘DVRS/VRX Enabled’ P25 PSUs.
