High Impedance Phones :
Some phones draw very little current when used. These phones also produce an un-
usually high level of speech. These two behaviors can cause a problem called "talk
off." If the user speaks loudly or blows into the phone, it may disconnect from the
talking mode and go back to dial tone. If this happens, you have a high impedance
phone and need to move jumper JP-20 on the circuit board.
JP-20 is located in the upper left side of the board and can be moved left and right.
The default is in the right position for "normal" phones. Lift the jumper and place it
across the two left pins. This should compensate for a high impedance phone. If there
are other normal phones also connected to the line, JP-20 may have to be kept in the
default position in order for all of the phones to ring correctly. Generally, when a
high impedance phone is connected with a normal phone the "talk off" problem is
improved.
Please Note: High impedance telephones are typically the least expensive phones
available. We recommend that all high impedance phones be replaced.
