Assisted
Setup
Step 1
Pick up your telephone handset and call
1-800-283-5330 (a quiet line used for ET100
setup). When you hear silence on the other end,
set the handset down next to your phone (NOT
on the switch-hook module).
Step 2
Press and hold any MUTE button on the audio
module for a few seconds, until you hear the
prompt “setup enabled.” The POWER light will
be flashing red.
Step 3
Set the slide control on the bottom of the switchhook module to 8. Make sure the sensitivity
switch #4 (found on the side of the switch-hook
module) is down (off). If the MUTE lights on
the audio module are green, no adjustment is
needed. Go to step 4.
Move the slide control slowly down to 1. Stop
immediately when the MUTE lights turn from
red to green.
If the MUTE lights never turn green, reposition
the slide control at 8. Move the sensitivity
switch #4 (the switch farthest to the right) up
(on).
Slowly move the slide control down again. Stop
immediately when the MUTE lights change
from red to green.
If the MUTE lights NEVER turn green, call for
assistance at the number below.

hears static, a hum, or scratchy noises, position
sensitivity switch 2 up (ON) and 3 down (OFF).
Repeat steps 1 through 4.
THIS IS A ONE-TIME SETUP.

Operating the ET100 is practically identical to
operating your telephone because it uses your
existing telephone functions.
Operation
Making calls and beginning a conference
Pick up your handset from the telephone cradle
and dial out as normal. Place the handset on the
switch-hook module pad to begin the
conference. Or, place the handset on the switchhook module pad first and dial out as normal.
The conference will automatically begin.
Answering calls and beginning a conference
Pick up your handset from the telephone cradle
and answer the call as normal. After the
telephone call has been established, place the
telephone handset on the switch-hook module
pad. Or, place the handset directly on the
switch-hook module pad after answering the
call. The conference will automatically begin.
Hanging up a call
Place the handset on the telephone handset
cradle.
Adjusting the speaker volume
Press the VOL + or VOL - button on the audio
module. Press the VOL + and VOL - buttons
simultaneously to return the speaker volume to
normal (default) level.

environment where there is little or no
background noise.

will flash red when microphones are muted.
Press any MUTE button once again to unmute
all three microphones. All MUTE lights will
glow green when microphones are unmuted.

Leave the handset placed on the switch-hook
module pad, or pick up the handset from the
switch-hook module pad while using your
telephone as normal to put a call on hold,
transfer a call, access additional lines,
conference additional lines, hold a private
conversation, etc.
Note: The ET100 will provide full-duplex audio as
long as the phones on both ends of the conference
call provide full duplex features. (Speakerphones are
NOT full duplex.)
