Verifying signal strength

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:
