Zoom MAC quick start Echo Troubleshooting, Type AT &C0 &W &Y0 and press Enter, For low volume

Page 20

Type: AT &C0 &W &Y0 and press Enter.

Also make sure that the faxmodem initializa- tion string does not include &C1.

If your software requires that Data Carrier De- tect follow carrier, the above considerations apply in reverse. If you are having problems, include &C1 in the faxmodem initialization string.

Problem: The modem speaker volume is too low or too high.

Solution: If the software allows you to control the speaker, make sure the speaker is enabled and set to a comfortable volume.

If the software does not have speaker settings, add one of the following AT commands to the initialization string:

L1

for low volume

L2

for medium volume

L3

for highest volume

M0 to turn the speaker off entirely

For example, if you want the volume low and the software uses the initialization string AT&F, change it to AT&FL1.

Echo Troubleshooting

Problem: Each character you type either appears twice or no characters appear at all during data mode.

Solution: Make sure that your software is in full-duplex mode when you make a telephone call. If the remote modem is not also in full-duplex mode, change to terminal mode, type AT E0, and press Enter. Then turn on your communica- tions software’s local echo. Your software now echoes commands during terminal mode and any typing performed during data mode.
