HS-229  (430-0182)             Operation              Faxback Doc. # 6478

NOTE:  The unit turns itself off to save battery power during a call if
       there is not activity on the phone line for 30 to 90 seconds.
       The call is not disconnected, and the unit turns itself back on as
       soon as you or the caller speaks.

TESTING THE BATTERY

To test the battery, press BATT TEST on the front of the headset
amplifier.  If the BATT TEST/MUTE indicator does not light or lights
dimly, replace the battery.

PUTTING ON AND ADJUSTING THE HEADSET

1.  Place the headset over either ear so the wide part of the headset is
    behind the ear and the black earpad is next to your ear.

2.  Adjust the headset until it feels comfortable.

3.  Clip the modular connecting cord's attached lapel clip to a piece of 
    clothing.  Leave enough slack in the cord so you can move your head
    freely without applying tension to the headset.

4.  Hold the headset in place, then move the attached microphone boom
    until the microphone is parallel to or just below your mouth at a
    distance of 1 inch or less.

Caution:  The microphone boom swivels on the headset.  Do not bend the
          microphone boom while you adjust it or twist the microphone on
          the end of the microphone boom.

RECEIVING CALLS

1.  The first time you use the headset, slide VOLUME on the front of the
    headset amplifier all the way to the left.

2.  Put on the headset.

3.  Pick up the phone's handset and place it beside the base.

4.  The first  time you use the headset, slide SELECT to I.

5.  Slide HEADSET/HANDSET to HEADSET.

6.  Speak into the microphone in a normal voice, then adjust VOLUME to
    a comfortable listening level when the caller speaks.  If the
    caller indicates that your voice is too loud, low, or garbled, slide
    SELECT to II or III, then speak into the microphone again.  Leave
    SELECT at the setting where the caller hears you best.

NOTES:  Once you determine which SELECT setting works best, you should not
        need to change it again unless you mount the HS-229 on another
        phone.

        When you first put on the headset, you might not hear sound through
        it.  The headset turns itself on as soon as you or the caller speaks.

7.  When you are finished with the call, return the phone's handset to
    the base.

MAKING CALLS

When you use the headset with the phone, you can still use all of the
phone's features, including hold or special calling services.

7.  When the other party answers, speak into the microphone in a normal
    voice, then adjust VOLUME  to a comfortable listening level when
    the caller speaks.  If the caller indicates that your voice is too
    loud, low, or garbled, slide SELECT to II or III, then speak into
    the microphone again.  Leave SELECT at the setting where the caller
    hears you best.

NOTES:  Once you determine which SELECT setting works best, you should not
        need to change it again unless you mount the HS-229 on another
        phone.

        When you first put on the unit, you might not hear sound through

    handset to the base or press the phone's switchhook and make another

       all calls.

MUTING THE HEADSET'S MICROPHONE

on the front of the headset amplifier.  The BATT TEST/MUTE indicator
lights.  Press MUTE again to resume the call.  The BATT TEST/MUTE
