2.3.11 CONNECTING AN EXTENSION TELEPHONE OR ANSWERING MACHINE

Plug one end of the modular cord into the EXT.TEL jack on the rear of your machine. Plug the other end of the cord into a modular jack on a telephone answering device or a regular telephone if you wish to use it as an extension.

2.3.12 CONNECTING THE POWER CORD

Plug the female and of the power cord into the receptacle on the rear of the fax machine. Plug the other end into a standard AC outlet.

2-11

2.3.13 TURNING ON THE POWER

Press the power switch to the up (—) position to turn the power on.

When the fax machine is first powered on, all of the indicators will light and, through the LCD window, your fax machine will prompt you to wait until the fax machine warms up.

When time and date appears on the window, you can set up the fax machine. This mode is called the "standby mode."

Pick up the handset and hear a dial tone to be sure the fax machine is properly connected.

Notes:

• When the machine is ready to operate, the user must set current time & date and terminal ID according to the description in the operating and Installation Manual.

• The fax machine will always set itself to the automatic reception mode (FAX MODE) each time the machine is powered up. To change the receiving mode, press RCV. MODE. For more information on the receiving mode, see the operating and installation m manual.

2.3.14 MOUNTING OF THE ADDRESS LABEL

The address label paper is used to make a note of the number when the user stores numbers into one-touch dialing stations. It will remind the user of what telephone number is stored in each position.

Silence Detection Time

(Used in ANS/FAX mode only)

In ANS/FAX mode, after a call is picked up by the answering machine, your fax machine monitors the line.

When your fax machine detects a certain time period of silence or that the line has been released by the answering machine, the call will be treated as a fax message and your machine can begin to receive a fax.

You can limit the silence detection time to 12 seconds or select unlimited time.

Press YES if you want to limit the time to 12 seconds. Press NO if you want to select unlimited silence detection time.

Automatic Turnaround Polling

You can set your fax machine to turnaround poll another machine.

Press YES to poll a remote machine every time you send documents to the remote machine.

Press NO if you do not want turnaround polling.

If you have selected turnaround polling in Step 7, the fax machine prompts you to enter a 4-digit turnaround poll code. This code is required to access a remote fax machine secured with a poll code.

Power Save Mode

If you want to set your machine to power save mode, press YES. This setting allows your fax machine to shut off the machine’s printer

heater automatically after a document is printed, and to conserve electricity and reduce your utility bills. The fax machine automatically turns on the printer again when it receives a document or is instructed to make a copy. In the power save mode, it takes the machine a little longer to print out fax messages or copies, because it must first re-heat the printer.

If you press NO, the machine’s printer heater remains on all the time so the machine can start printing copies sooner.

If you want to set the time duration that the machine activates the power save mode, press YES. The machine goes to the power save mode from a specified start time to a specified end time every day.

If not, press NO. The machine activates the power save mode all the time.

The machine displays the currently selected start time at which the fax machine goes to the power save mode.

Enter the desired start time using the dial keypad. Use 24-hour format to select time (Military time).

When the time appears correctly in the display, press YES. The machine displays the currently selected end time at which the fax

machine exits from the power save mode. Enter the desired end time using the dial keypad. Use 24-hour format to

select time (Military time). When the time appears correctly in the display, press YES.

Dial Mode

Select the type of dial mode your fax machine is connected to. Press YES if the fax machine is connected to a tone dial telephone line.

Press NO if the fax machine is connected to a pulse dial telephone line.

Security Communication (For Msys5700 Only)

The feature allows your fax machine to send and receive documents only to and from predetermined locations where fax machines have the security code that matches your security code.

Press YES if you want your fax machine to send or receive documents in the security communication mode.

Press NO if you want normal communication mode. If you have selected Security Communication in Step 14, the fax machine

prompts you to enter a 4-digit security code. The code is used to identify participating stations as members of the closed

network. This ensures only authorized parties can communicate with your machine.

When the code appears correctly in the display, press YES.

Error Correction Mode

Error Correction Mode (ECM) compensates for poor line quality and ensures accurate, error-free transmission with any other ECM-equipped facsimile machine. If the line quality is poor, transmission time may be increased when ECM is enabled.

Press YES to enable ECM. Press NO to disable ECM.

Automatic Reduction

When receiving or copying a document as long as or longer than the paper installed into your fax machine, the fax machine can reduce the data of the document to fit on a standard A4 (8.5” x 11”) size paper. The rate of the reduction is as follows:

If the fax machine can not reduce the data to fit on one page with the feature enabled, the data is divided and printed out in actual size on two sheets or more if needed.

Press YES if you want to reduce the incoming page that may need to be divided into two pages with only a few centimeters on the second page.

Press NO if you do not want to reduce the receiving document. The overflowed data will be printed out on a second page.

Automatic Discard

When receiving or copying a document as long as or longer than a standard A4 size paper installed into your fax machine, you can set the fax machine to discard any excess image at the bottom of the page to fit on a standard A4 size page.

If the received page is outside the margin you set, it will be printed on two sheets of paper at the actual size.

If the data is within the margin, and Auto Reduction is turned on, it will be reduced to fit on the appropriate size paper (Discard does not take place). If Auto Reduction is turned OFF or fails, the data within the margin will be discarded.

If the margin is set to 00, a second blank sheet may be printed. Enter the desired discard size, using the dial keypad, then press YES.

Automatic Redial Interval

Your fax machine can automatically redial a remote fax machine if it does not answer the first call or if it was busy.

Enter the number of minutes (from 0 to 7 minutes), using the dial keypad, to wait before redialing the number that was busy on the last try. Then press YES.

Note: If you enter 0, the fax machine will not wait. It will redial the number immediately following the preceding try.

Automatic Redial Number

Enter the number of attempts (from 0 to 7 times) to redial the number before giving up. Then press YES.

Note: If you enter 0, the fax machine will not redial at all

Ring Before Answer

Enter the number of rings (from 1 to 7) your fax machine should wait before it answers an incoming call. Then press YES.

If you enter 3, the fax machine will answer calls on the third ring.

To give you time to manually answer your calls when you are present, set this option for at least four rings.

To return to the standby mode, press STOP.

To verify your setting, print the System Data list.

The maximum TX speed can be limited to 14400(Msys5700), 12000(Msys5700), 9600, 7200, 4800 or 2400 bits per second. when the TX speed is set to 9600 or 7200 the RX speed can be any V.29 or V.27ter speed When the TX speed is set to 4800 or 2400, the RX speed can be any V.27ter speed.

If the error rate exceeds the chosen rate, fall back occurs which will lower the baud rate automatically down to as low as 2400 baud until the error rate is less than the chosen rate.

You can set the level of transmission signal. Typically, Tx level should be under -9 dBm. The level within the range of -9 dBm to -15 dBm is acceptable. Enter the desired value using the dial keypad.

With copper wire, lower frequencies are attenuated less than higher frequencies. The longer the cable, the more pronounced the effect. This feature compensates for some loss caused by the cable length.

High sensitivity is between 0 and -40 dBm. Normal sensitivity is between -5 and -43 dBm.
