Cabling Guide
GSM Instructions
Step 1 – Activate Your Wireless Account
Please see the wireless account Activation Notices located on the CD if you need
to activate your account.
Phone Numbers: Each 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.
Step 2 – Installing the SIM Cards
The MultiVOIP GSM 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 SIM cards, do the following:
1. Remove the three highlighted screws from the back as shown below.
2. Slide the cover forward and up to remove it.
3. Insert the SIM cards into the units at the front of the MVPGSM.
4. Verify that the SIM cards fit into their holders properly and then replace
the cover.
Step 3 – Signal Strength
Before final placement or mounting, ensure that the wireless signal strength is
strong enough for the chosen area. To find your signal strength, look at the
LED indicators on the front panel. If the first indicator is lit (“one bar”), there is
sufficient signal strength for proper operation. If two or three are lit (two or
three “bars”), then there is good signal strength and operation will not be
impaired.
