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 24
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 53i 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
53i 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.
