Multi-Tech Systems, Inc. MVPGSM 10
Chapter 2 – Getting Started
Introduction
The MultiVOIP GSM is equally usable as tabletop unit or mounted in a location with good reception. The initial
setup is best performed before any mounting is done.
Installing SIM Cards
The MVPGSM requires at least one SIM card (Subscriber Identity Module) to operate on a GSM network. To
install the SIM cards, do the following:
1. Turn the unit off and disconnect the power cord. Remove the screws from the back of the unit.
2. Electrostatic discharge (ESD) is the release of stored static electricity that can damage electrical circuitry or
components. Static electricity is often stored in your body, and discharged when you come in contact with
an object of a different potential.
Perform the procedure below (removal of chassis cover) described in this section only at an ESD workstation
using an antistatic wrist strap. If such a station is not available, you can provide some ESD protection by
wearing an antistatic wrist strap and attaching it to a metal ground screw (lug) next to power switch of the
chassis.
3. Slide the cover forward and tilt the rear of the cover up as you remove it.
4. Insert the SIM cards into the SIM card slots on the internal wireless modems. Each modem has a graphic
line depicting the correct SIM card orientation.
5. Verify that the SIM cards fit into their holders properly and then replace the cover by reversing what you
did in step 3. Align the “teeth” at the front of the unit first.
6. Attach the screws and then the power cord.
Modem Numbering
The MVPGSM-2 modem numbering corresponds to the printing on the front panel. You may also tell the
numbering by the wires routed to the antennas.
