Powering up the VRX1000
The VRX1000 powers up together with the MSU. The power up mode and channel are
programmable. Depending on the programmed personality, the VRX1000 can power up
in one of the following states:
• VRX1000 Disabled mode, last selected VRX1000 channel
• OFF mode
• SYSTEM mode, last selected VRX1000 channel
• SYSTEM mode, preprogrammed VRX1000 channel
• LOCAL mode, last selected VRX1000 channel
• LOCAL mode, preprogrammed VRX1000 channel
• If the VRX1000 powers up on a ‘strapped’ mobile radio channel, the VRX1000
will be steered according to the Talk Group selected on the MSU. The steering
may involve both VRX1000 channel and mode change.
Turning ON the VRX1000
When the MSU is powered up, the VRX1000 can be activated by one or more of the
methods described in the following section.
• The VRX1000 is ON when SYSTEM (or optionally LOCAL) mode of operation is
selected.
• The VRX1000 is OFF when OFF mode is selected.
• The VRX1000 is disabled when a “VRX1000 Disabled” Mode / Channel is
selected on the APX MSU or if the currently selected VRX1000 and MSU modes
are incompatible (such as TDMA MSU mode and P25 Digital VRX1000 channel).
NOTE:
The VRX1000 can only be activated when a compatible “VRX1000 Enabled” mode /
channel is selected on the APX MSU.
Activating the VRX1000 via the Control Head
Ensure the MSU is powered up and a VRX1000 Enabled TG / channel is selected on the
control head.
To activate the VRX1000:
• Press the DVRS menu item to enter the ‘DVR/VRX1000 Control Mode’.
• Once in the ‘DVR/VRX1000 Control Mode’ screen, press the MODE button to
toggle the available VRX1000 modes until the desired mode is selected.
• Press the SEL button or wait the preprogrammed time until the ‘DVR/VRX1000
control Mode’ screen times out. The last selected VRX1000 mode becomes
effective.
• Long press of the DVRS menu item can be programmed to turn the VRX1000
ON/OFF.
Pressing the DVRS button allows the user to enter the ‘DVR / VRX1000 Control Mode’
and to select the desired VRX1000 mode and channel.
