No Dial Tone on the A300

Last Updated: Jun 15, 2017 11:16AM CDT
If you have no dial tone on the A300:

1. Activate the speakerphone function by tapping the green Talk key a second time.  If the speakerphone works, there is something wrong with the earpiece speaker and the phone needs to be sent in for service. 

2. If the speakerphone does not work, make sure the screen does not say ‘searching’ or ‘unregistered’.  If it says ‘searching’, check electrical connections.  If it says ‘unregistered’, re-register the handset.  If it has a HS number, move to step 3. 

3 .Check phone line connection. If you have a cell phone, call the house number and see if it rings.  If it does, you should be able to answer it.  If it doesn’t, the phone has no connection to the line and the phone needs to be sent in. 

4. What do people say happens when they call the number associated with the phone?  If people say the line is busy, the phone holds the line open and the phone needs to be sent in.
