If you cannot hear the caller after answering a call, please check the following:
Verify the handset cord is plugged into the correct port.
There are two ports on the side of the phone: one for the handset and one for a headset.
Look for the small icons near the jacks to confirm the correct port.
A common mistake during setup or relocation is plugging the handset cord into the headset jack.
Place a call on speaker phone mode to confirm the handset is not plugged in correctly.
Check the handset volume.
Press the Volume Up button on the phone’s base (located below or near the OK button) to ensure the volume is turned up fully.
