I can't hear a dial tone in the
headset.
The sound is distorted.
I hear echo in the headset.
People I talk to can hear a buzz in
the background.
The handset lifter is installed but
does not lift the handset.
When I dial from my softphone
application, nothing happens.
Adjust the configuration on the switcher until a dial tone is heard.
If the volume is too low, adjust the listening volume dial on the
bottom of the switcher.
Make sure the lifter is lifting the handset high enough too operate
the hookswitch; set to a higher setting if necessary.
Lower the speaking volume dial and/or listening volume dial on the
switcher. For most telephone the correct setting is position 2.
If your desk phone has a volume control, lower until the distortion
disappears,
Lower the listening volume and the speaking volume dials on the
switcher. For most telephone, the correct setting is position 2.
Adjust the Configuration Switch. The most commonly used
position is "A", which is the default position.
If the power supply (HL10 lifter only) is plugged into a power strip,
plug it into the wall directly.
Be sure the optional AC power adapter is firmly pushed into the
handset power jack on the switcher.
