Problem
How can I change the speaker vol-
ume on the modem?
Modem does not dial or dials incor-
rectly.
Solution
• The volume can be changed through AT Commands. Use
the following AT Commands to change the volume levels:
ATL0 Set lowest speaker volume
ATL1 Set low speaker volume
ATL2 Set medium speaker volume
ATL3 Set high speaker volume
ATM0 Turn speaker off
ATM1 Turn speaker on during handshaking and while
receiving carrier
ATM2 Turn speaker on during handshaking and while
receiving carrier.
ATM3 Turn speaker off during dialing and receiving
carrier and turn speaker on during answering.
• Are you cable and phone line connections secure?
• Is there another phone extension on the same line in
use?
• Are you using a standard analog phone line? Digital
phone lines will not work with this modem.
• Is the telephone number correct?
• Did you enter a “1” before the area code when dialing
long distance?
• Are you required to enter a prefix, such as a “9” in your
settings.
• Is the other line busy or not answering? Make sure it is
available before calling.
