Chapter 1: VML750 Description Figure 1-1 VML750 - General View Item # Description Modem LED Indicator Panel (Front Panel) Connector Panel (Back Panel - not shown) For detailed specifications of the VML750 unit, see Appendix A, "Specifications". Modem ■ ■ ■...
■ ■ ■ ■ ■ ■ ■ ■ The VML750 Connector panel consists of the following (see Figure 1-3): Figure 1-3 Connector Panel Item # Description RF SMA female type connector (WWAN2 DIV/WiFi) RF SMA female type connector (WWAN2 main)
■ The Power button is used to turn the VML750 On or Off when Ignition Sense is disabled. If the Ignition Sense is enabled, you also need to turn your vehicle ignition switch to On. This button is also used to apply factory reset.
If your LTE modem is intended to home on your private Motorola LTE network, you are provided with a Motorola LTE SIM card (to be inserted into SIM1 slot). If your LTE modem is intended to home on a public carrier LTE network, you need to obtain a SIM card from that public carrier and insert into SIM2 slot.
• Do not attach components to any part of the vehicle subjected to excessive vibration. • Do not mount the VML750 unit on a flat surface where the unit could become partially submersed in water. • The proposed location of the equipment being mounted or wires/cables attached must not interfere with driver/passenger seating or leg space.

Install this product in a vehicle in accordance with the vehicle manufacturer’s guidelines and the instructions detailed in this manual. Use only the Motorola parts specified in this manual. Check the required mounting locations. It might be necessary to penetrate the firewall to reach the battery.
Refer to the Safety Instructions in “Product Safety and RF Energy Exposure Booklet for Mobile Two-Way Radios Installed in Vehicles or as Fixed Site Control Stations” P/N 6881095C99. The VML750 must be installed in the car’s trunk, on the floor or the side walls (cooling fins facing up, or to the side).
Installation Constraints Chapter 2: VML750 Installation The VML750 must not be installed with the cooling fins facing down. Failure to comply may cause overheating problems and performance degradation. Figure 2-1 shows a schematic VML750 installation in a car. Figure 2-1 VML750 - Schematic Car Installation Before beginning the installation process make sure that the space available at the installation site is adequate for the modem and its accessories.
