READ THIS BEFORE INSTALLATION

We have designed the ET-152 Headset Telephone to conform to federal
regulations and you can connect it to most telephone lines.  However, each
device you connect to the phone line draws power from it.  This power draw
is the device's Ringer Equivalence Number, or REN.  The REN is shown on the
bottom of the ET-152.

If you use more than one phone or other device on the line, add up all the
RENs.  If the total is more than five (or three in rural areas), your
phone(s) might not ring.  If ringer operation is impaired, remove one of
the devices from the line.

FCC STATEMENT

The ET-152 Headset Telephone complies with Part 68 of FCC RULES.  You must,
upon request, provide the FCC registration number and the REN to your
telephone company.  Both numbers are marked on the bottom of the ET-152.

NOTE:  You must not connect the headset telephone to:

       Coin-operated systems

       Party-line systems

       Most electronic key telephone systems 

CONNECTING TO THE PHONE LINE

1.  Plug one end of the supplied modular cord into the ET-152's TEL LINE
    jack.  Then plug the other end into the telephone line's wall jack.

2.  Plug the headset's modular cord into the ET-152's HEADSET jack.

ADJUSTING THE HEADSET

1.  Place the headset on your head.

2.  Adjust the headset band until it rests with almost no pressure on your
    ear and the top of your head.

    If the headset is loose, remove it and flex it inward slightly to
    tighten it.  If the headset is tight, gently pull the headset band out
    to loosen it.

3.  Hold the headset in place, and turn the microphone boom until it is
    about even with your chin.  Experiment until you find the most
    comfortable position.

4.  Route the headset's modular cord through the lapel clip's channel and
    attach the lapel clip to your clothing.  Leave enough slack in the cord
    so you can move your head without pulling the headset.

SETTING THE DIALING MODE

Set TONE/PULSE for the type of service you have.  If you are not sure
which type of service you have, do this simple test.

1.  Set TONE/PULSE on the side of the dialer to TONE.

2.  Press TALK/HANG UP so its indicator lights and listen for a dial tone.

3.  Press any number other than 0.  If the dial tone stops, you have touch-
    tone service.  If the dial tone continues, you have pulse service.

4.  If you have pulse service, set TONE/PULSE to PULSE.

SETTING THE RINGER OFF/ON SWITCH

You can set RINGER to OFF or ON.  With RINGER set to OFF, the dialer does
not ring, but you can still make outgoing calls.  If you hear an extension
telephone ring, you can answer incoming calls.

USING THE BELT CLIP

Use the ET-152's belt clip to hang the dialer on your waistband so you can
carry it with you wherever you go.

To attach the belt clip to the ET-152, place the belt clip in the slot,
then slide it in an upward position until it locks into place.

To remove the belt clip from the ET-152, press the belt clip's tab and
slide it off in a downward position.
