IMPORTANT NOTE: The audio may activate in the middle of a call due to
factors like excessive wiring (see page 12 item 8), bad or old wiring , existing
unstable lines, sparks, too many wall jacks , Noisy phone lines, Bad
telephones, “Hot Lines” (see P6 special cases)
If that ever happens, press the FLASH button to stop the audio! and
continue your conversation The FLASH button is found on every telephone,
it could be labeled as CALL WAIT / FLASH or LINK or ON or TALK button
Connection Test: To confirm that you have connected everything correctly:
Set Mode switch to SD, Turn Speaker ON, make sure you can hear the audio from the SX8800, adjust the
volume up (clockwise) if needed, set two ABC switches in front to C position and the two 123 switches in the back
to 3 position,
select line 1 on the phone, L1 LED on SX8800 must turn ON and you should hear audio from the phone Line 1
select line 2 on the phone, L2 LED on SX8800 must turn ON and you should hear audio from the phone Line 2
select line 3 on the phone, L3 LED on SX8800 must turn ON and you should hear audio from the phone Line 3
select line 4 on the phone, L4 LED on SX8800 must turn ON and you should hear audio from the phone Line 4
Double check your connections or adjust the volume if needed
This completes the test you should change the ABC and 123 switches now to proper setting as follows:
Switch setting: Please Read the Operation instructions for each setting carefully
There are two pair of 3 position switches on the SX8800 that control the activation method, you need to select
the proper setting based on your type of phones:
A1, A2, A3: Hold button activation
Use one of these settings when all phones are corded & are same model (for example all are ATT 992) and are
compatible with Hold button activation (see the list in page 3)
B1, B2: These two settings utilize Flash then Hold activation method, this setting
supports any phone and any mix of brands with instant activation
by pressing Flash then Hold
• Use B1 or B2 settings if your phones are Cordless type (including corded base station + portables)
• If you have mixed cordless type phones with corded type phones
• If you have corded type phones that are not all the same model for example ATT brand and
Panasonic brand are both used in your office
• If you have any phone that does not activate by pressing Hold (for example ATT 1040)
B3: Hold button activation or Flash See page P4 for full details
C1, C2: Voice Activation Mode These two settings utilize Delayed Hold activation method, most phones
cordless or corded or mixed can be activated for music on hold in less than 15 seconds after you press HOLD
C3: Test mode
Note: Do not set the volume too loud it may flicker or shut off the on-hold audio
Note: Do not use a Cell phone near the device to setup or test the device Use a fax line, etc

Voice Deactivation: if the call has been on Hold at least a few seconds, it can also be deactivated by
just speaking over the Audio for example say : “Hi I am Back”
If for some reason you are not able to voice -deactivate, try speaking a little louder and more direct
into the microphone, if that does not work hang up and set the switches to B2 Remember you can
always use the Flash button to deactivate the audio as well
Want to use just one button ? Press to activate MOH and when ready to go back to

Operation in C1, C2 settings:
C1 and C2 use “voice activation” method, this mode of operation supports most phones or brands by
just using the Hold button but with slightly longer activation time (about 10 to 15 seconds after hold is
pressed)
In “Voice activation” mode, the device needs to hear you well therefore speak as close as
possible to the microphone, If you are on a speakerphone or using a headset speak clearly and
louder into the microphone Be sure to read the NOTES in this section
To activate: after you receive or make a call, you need to speak and say something before
pressing the button Audio activates less than 15 seconds later and the corresponding L1
… L4 light on this device will start blinking
To deactivate hold music just re-select that line and Speak Over the audio, for example say : “Hi I
am Back” , the moment the device hears it will stop the hold-music
Note: You may also deactivate the hold-music audio by pressing the button
NOTE1: If you hear the audio during your conversation , say something to stop the audio, this can
happen if you or your party are not talking to each other for about 7 seconds (after 2 times device will stop
activating audio when non speaking for the rest of the call)
NOTE2: If for any reason the hold music is playing, do not panic, simply speak over the audio to stop
it or press FLASH to stop it
C2: If for some reason you are not able to voice activate or voice -deactivate, Hang up and set the
switch to C2 then try again using the above instructions
Back ground Music: SX8800 can be used to provide just a back ground music during all the calls and all
the lines In this case the device will not provide the Music-on Hold function however the same back
ground music is heard by the callers when the calls are placed on Hold
To set the device for background music use an audio file in the SD card with soft music or connect a
music source to EXT jack and set the Mode Switch to EXT and turn the volume low (counterclockwise)
set the switches to C3
During the conversations the music will be heard, make sure volume is low enough to allow talking

or A3 settings
• If answering a call allow 1 second before pressing Hold
•
You may need your “Local service” to be with the
dominant phone company in your area (not 3
rd
party local
service)
•
Is your location within city limits? are all your phone
numbers DSL qualified? your location may need to be
close enough to your phone company’s central office to
guarantee for Hold button activation That is why some
discount phone companies service does not work even
though you have compatible phones for Hold activation If
so you need to use the device in B1 or B2 setting via
Flash then Hold or C1, C2 settings with delayed activation
•
Some telephones have special cases (see page 6)
