Troubleshooting

I do not hear any voice from the other party

1. Check all cable connections:

• Telephone - Check the connection between ampliﬁer and telephone.

• Handset - Check the connection between ampliﬁer and handset.

• Handset Operation – Check that the handset works when selected by Headset/Handset
switch

• Headset - Check the connection of the Quick-disconnect cable to the ampliﬁer

• Headset Compatibility – Check that your headset is compatible with the A10L. Swap with
a known working headset, if available.

2. Check that the handset/headset selection switch is properly pressed.

3. Check the position of the “N-R” switch (see Section 3).

The other party’s voice is low in volume

1. Increase and adjust the listening volume level.

2 If the MUTE LED is dim, replace the batteries

3. Check your headset by swapping it for a known working headset
