If you intend to use a phone handset, connect it to the MultiModem now.     

(use of handset optional;
  handset cable not included)

For initial configuration of your wireless device, Multi-Tech offers a Windows

® based mobile Phone 

Tools application. 

To load mobile Phone Tools, click on the mobile Phone Tools icon on your product CD and follow 
the on-screen prompts. 

The Wireless MultiModem establishes a call if the signal is sufficiently strong. To verify the signal 
strength, do the following: 

1. Using the HyperTerminal program at the computer to which the Wireless MultiModem is 

connected, type the AT command AT+CSQ.  A value for the received signal strength will be 
returned. 

2. Verify the result with the following chart: 

Value of signal strength 
(AT+CSQ response) (RSSI) 

Signal strength 

10 - 31 

Sufficient 

0 - 9 

Weak or Insufficient 

99 Insufficient 

 

In this procedure, you will verify that the Wireless MultiModem has been registered on the wireless 
network.  To do so, you will use the common communications program Hyperterminal.   

1. Using the Hyperterminal program at the computer to which the Wireless MultiModem is 

connected, type the AT command AT+CREG?.  A value for the modem’s network registration 
status will be returned. 

2. Verify the result with the following chart: 

0, 1 

Yes 

0, 5 

Yes 
(registered roaming) 

  If the modem is not registered, perform the procedure for verifying signal strength to determine the 

strength of the received signal.
