Alignment and Troubleshooting Data Setup Send Level You can set the level of the transmission signal. Typically, the Tx level should be under -12 dBm. Caution : The Send Fax Level is set at the best condition from factory. Never change settings arbitrarily. DTMF Level This is a setting value of the High level tone and low level tone at DTMF mode. (Not dial mode) Pause Time It shows the delay time when receving the pause input at auto dial. Dial Mode This function can choose dial method. *Default : Dial (Dial/Pulse) Modem Speed You can set the maximum modem speed. However, outbound communication is switched automatically to match the standard of the receiving fax. Therefore, when communicating with a lower speed modem, the outbound communication speed will be set to low. This will allow for better transmission/reception by the receiving fax. It is best set 33.6Kbps as default setting. Error Rate When the error rate is about exceed the set value, the Baud rate automatically adjusts to 2400 bps.
