Troubleshooting Solutions
Why is my display blank?
Ensure that power is being provided to your phone. Make sure your phone is plugged into a
power source.
Why is my speakerphone not working?
If you press the button and the speaker light flashes and you do not hear dial tone through
the speaker phone, the Set Audio option in the phone’s Options list has been set up for headset
use. Press a second time and if the light goes out, the phone has been set up to be used
only with a headset or handset. If the light stays on steady and you hear dial tone, the phone has
been set up so that you can alternate between the speakerphone and the headset by pressing
. See the section, “Set Audio” on page 27 for instructions on how to change the Set Audio
option.
Why can’t I get a dial tone?
Check for any loose connections and that the phone has been installed properly. For installation
instructions, please refer to the “Installation and Setup” section in the Aastra 6753i Installation
Guide provided with your phone.
Why doesn’t my phone ring?
Check the ring volume on your phone. It may be turned down or turned off. To adjust the ringer
volume setting, press the volume button when the phone is on-hook and idle. For more
information, refer to the “Adjusting Volume section” in the Aastra 6753i Installation Guide
provided with your phone.
Why is the light not coming on with a new Voice Mail Message?
Your phone system or service provider must provide “Visual” Message Waiting service for this
function to work. Check with your System Administrator for more information.
Why is my handset not working?
Check to ensure that the handset cord is fully connected to both the phone and handset. See the
section “Connecting a Handset or Headset” in the Aastra 6753i Installation Guide for
information.
