Notes

• Conduct connections instructed on page 10 or 11 first, when
inserting battery for backup (not supplied) in case for a power
failure. If “POWER FAILURE” remains displayed when you
connect the AC power adaptor to an AC outlet for the first
time, remove the battery from the phone and unplug the AC
power adaptor, then plug it into an AC outlet.

• Use only the supplied AC-T71 AC power adaptor. Do not use
any other AC power adaptor.

• Connect the AC power adaptor to a continuous power
supply.

• Place the phone close to the AC outlet so that you can unplug
the AC power adaptor easily.

Tips

• Phones other than the IT-M704 and IT-M804 phones cannot be
connected to LINE 1 jack.

• Connection and utilization of Private Branch Exchange (PBX)
is not possible.

Connecting a computer or FAX

You can connect a computer or FAX, etc. to
the DATA jack.
For the line to be used for data
communication, select L2, L3 or L4 using
the DATA LINE SELECT switch.

Notes

•“LINE 2”, “LINE 3” or “LINE 4” is used for
receiving or sending computer or FAX data in
addition to making or receiving calls.
If a call comes in on the line selected with the
“call waiting” service while a computer or
FAX connected to the “DATA” jack is
receiving or sending data, that data may be
effected.
If you have data communication frequently,
we recommend that you and your callers use
the line selected for data communication only.

• Connection to ADSL devices is not possible.

• Noise may occasionally be heard on other

lines during data communication depending
on the condition of the indoor wiring.

• Do not bring your hand or other objects too close to the microphone
or you will hear a shrill noise (“feedback”).

• When the speaker volume is loud, or the telephone has been placed
close to a wall, you may find that the volume drops suddenly. This is
due to a circuit in the telephone designed to protect against
feedback. In such cases, lower the speaker volume slightly.

Step 2: Setting up the phone (continued)

Notes

• Conduct connections instructed on page 12 or 13 first, when
inserting battery for backup (not supplied) in case for a power
failure. If “POWER FAILURE” appears on the display instead
of “NO AREA CODE” when you connect the AC power
adaptor to an AC outlet for the first time, remove the battery
from the phone and unplug the AC power adaptor, then plug
it into an AC outlet.

• Use only the supplied AC-T71 AC power adaptor. Do not use
any other AC power adaptor.

• Connect the AC power adaptor to a continuous power
supply.

• Place the phone close to the AC outlet so that you can unplug
the AC power adaptor easily.

Tips

• Phones other than the IT-M804 and IT-M704 phones cannot be
connected to LINE 1 jack.

• Connection and utilization of Private Branch Exchange (PBX)
is not possible.

Connecting a computer or FAX

You can connect a computer or FAX, etc. to
the DATA jack.
For the line to be used for data
communication, select L2, L3 or L4 using
the DATA LINE SELECT switch.

receiving or sending computer or FAX data in
addition to making or receiving calls.
If a call comes in on the line selected with the
“call waiting” service while a computer or
FAX connected to the DATA jack is receiving
or sending data, that data may be effected.
If you have data communication frequently,
we recommend that you and your callers use
the line selected for data communication only.

ELECTRICAL ADJUSTMENT

The Adjustment method was changed.

4-1. 450kHz DATA RECEIVER ADJUSTMENT

Setting :

1) Connect the oscillator to LINE1 (CN1 (pins 3 and 4)) and set the frequency to 450 kHz (Deviation = OFF).

2) Adjust the output of the oscillator so that the level meter reads out – 61 dBv.

Procedure :

1) Turn the core of IFT1 (1

ST IFT) counterclockwise to set the core to the top position (where the core is most off). Verify that TP70 (IC804

1Pin COMP OUT) is at “HIGH” level (approx. 5 V) with the oscilloscope.

2) Slowly turn the core of IFT1 clockwise and stop to turn it at the position where TP70 is at “LOW” (approx. 0 V).

Note : These is no adjustment of IFT2.

• 2 : nonflammable resistor.

• C : panel designation.

Note: The components identified by mark 0 or dotted line

• U : B+ Line.

• Power voltage is dc 12 V and fed with regulated dc power

• Power voltage is dc 12 V and fed with regulated dc power

• Voltage and waveforms are dc with respect to ground

• Voltages are taken with a VOM (Input impedance 10 MΩ).

• Waveforms are taken with a oscilloscope.

• Circled numbers refer to waveforms.

• Signal path.

For Printed Wiring Boards:

• X : parts extracted from the component side.
