Page 11: About This Manual
When a Portable Subscriber Unit (PSU) has difficulty reaching a system tower, a VRX1000 helps by linking the PSU to a higher power mobile radio or MSU. The VRX1000 is designed to interface seamlessly to Remote Mount Motorola Solutions APX Series MSU with or without a Control Head (O2, O3, O5, O7, O9, or E5). -

MSU filter when an in-band VRX1000 Disabled channel is selected. When the VRX1000 is paired with a non-APX 8500 MSU, the switch bypasses the filtering at the output of the MSU when a VRX1000 disabled talkgroup (TG) is selected on the MSU Control Head. -
Page 16: Rf Bypass Switch With Apx 8500 Msu And All Band Antenna
The VRX1000 is equipped with an internal RF bypass switch. The bypass switch bypasses the MSU filter output to allow access to the full frequency band when VRX1000 is not enabled, or to block certain frequencies when VRX1000 is active to ensure interference-free communication. -
Page 17: Status Lights
Primary and VR On Lights The VRX1000 status icon located on the top-right corner of the Control Head can be used to determine when the repeater is turned on and whether it is acting as a Primary or Secondary device. Users can configure a more obvious light indication of the VRX1000 status. -
