3. Input COPY/B FILENAME PRN at the MS-DOS and push the ENTER key . (filename : the latest ROM file name when the downloading)

4. After the download is completed, the system will be automatically initialized.

• KEY TEST

The function is to test the capacity of product in the production progress. Service person doesn't need to use it.

FAX SETUP

• MODEM SPEED :

You can set the maximum modem speed. Communication is done with modem speed automatically set at lower speed when communicating with the modem with lower speed since communication is done on the standard of the side where modem speed is low for transmission/reception. It is better set 33.6KBPS as default setting.

• SEND FAX LEVEL:

Y ou can set the level of the transmission signal. T ypically , the Tx level should be under -12 dBm.

Caution : The Send Fax Level is set at the best condition in the ship-

ment from factory . Never change settings arbitrarily.

• 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 ship-

ment from factory . Never change settings arbitrarily.

• DTMF HIGH LEVEL :

Select high frequency level when dialing in the MF mode.The input range is between 00~15dBm.

Caution : The Send Fax Level is set at the best condition in the ship-

ment from factory . Never change settings arbitrarily.

• DTMF LOW LEVEL :

Select high frequency level when dialing in the MF mode.The input range is between 00~15dBm.

Caution : The Send Fax Level is set at the best condition in the shipment

from factory. Never change settings arbitrarily.

• P AUSE TIME :

Pause time mean delay time (unit: second) inserted between dial number signal and the next number of signal in the automatic dial (One touch, Speed dial, Redial) and the manual dial.

Caution : The Send Fax Level is set at the best condition in the shipment

from factory . Never change settings arbitrarily.

• ERROR RA TE :

- 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%.
