Select a wireless network provider and follow their directions to activate your account and receive your SIM 
cards. 

Every channel will have its own unique phone number. The phone number may simply be given to you 
by your wireless service provider or it may be on the SIM card or both. Wireless provider 
implementations may vary. 

The MVPGSM requires the power supply connection to begin operation. It also requires a SIM card (Subscriber 
Identity Module) to operate on a GSM network. To install the modem, do the following: 

Turn the unit off and disconnect the power cord. Remove the three highlighted screws from the back as 

shown below. 

Slide the cover forward and up to remove it. 

Insert the SIM cards into the units at the front of the MVPGSM. 

 

Verify that the SIM cards fit into their holders properly and then replace the cover. Attach the power cord. 

Turn the unit on and verify that the Power LED is lit and that the Boot sequence is finished (Boot LED is no 

longer active), then wait for the Link Status (LS) LED to show that the MVPGSM channel is registered on the 
wireless network (flashing 75 ms on and 3 seconds off). Once registered, the Signal Strength LEDs should be 
referenced for the strength of signal in its current location. 

 Before final placement or mounting, ensure that the wireless signal strength is strong enough for the 

chosen area. If no LEDs are lit, there is insufficient signal strength for proper operation. If one or 
more are lit, then there is good signal strength and operation will not be impaired. Finding a location 
with the strongest signal strength is desirable.
