Aspire Keyset Speakerphone Problems When Used with Analog Trunks

Some customers may be experiencing squealing/howling-related feedback when making a handsfree inter-
com call to another Aspire keyset. This is caused by the handsfree microphone element and/or rubber micro-
phone holder not being seated properly.
To resolve this problem:
● Disassemble the phone using the steps below and inspect/reseat the handsfree microphone element to
ensure that it is bottomed out within the rubber mic holder and that the rubber mic holder is seated prop-
erly within the plastic circular well. Check to make sure the small PCB that holds the mic holder in
place is properly secured.
1. Remove the four screws that hold the base plastic to the top panel and remove the base from the
phone.
2. Turn the phone so that the dial pad and keys are facing down.
3. Locate the handsfree mic assembly in the lower left corner of the phone.
4. Make sure the mic element is seated all the way down inside the white rubber mic holder and reseat
the rubber mic holder so that it is seated at the very bottom of the round plastic mic housing.
5. Using a small flat screwdriver, carefully press the mic element down inside the rubber mic holder.
Do not press on the solder joints of the two wires connected to the mic element.
