It is better set 26.4KBPS as default setting. � If the remote machine is busy when the machine sends a fax using automatic dialing, the machine automatically redials the number. Select the time interval between automatic redial attempts. Enter the desired redial interval using the number keypad: 1 - 15 minutes.

REDIAL COUNT

If there is no response after redialing by the times already set, redial is no longer attempted. No redial is attempted if the settings is 0. Enter the desired times from 1 through 5.

DIALING MODE

SILENCE TIME
� In ANS/FAX mode, after a call is picked up by the answering machine, the machine monitors the line. � If a period of silence is detected on the line at any time, the call will be treated as a fax message and the machine begins receiving. � Silence detection time is selectable between limited (about 12 seconds) and unlimited time. � When '2 sec' is selected, the machine switches to receiving mode as soon as it detects a period of silence. When 'unlimited' is selected, the machine waits until the answering operation is concluded even though a period of silence is detected. After the answering operation is concluded, the machine switches to receiving mode.

RCV FAX LEVEL
� You can set the level of the receiving signal. � The reception level may be too low due to the cable losses. � If it is set to -43 dBm, the reception sensitivity will be between 0 and -43 dBm. If it is set to -48 dBm, the reception sensitivity will be between 0 and -48 dBm. � Caution: The Send Fax Level is set at the best condition in the shipment from factory. Never change settings arbitrarily.

ERROR RATE FLASH TIME
� Set the flash time to 80, 280, or 600 milliseconds. � When the error rate is about to be over the setting value, the Baud rate automatically lowers up to 2400 bps to make the error rate remain below the setting value. � You can select the rate between 5% and 10%.
