Check the phone for a volume control. Adjust accordingly. Check the handset cord to see if it is properly seated or for frayed cord. Check to see if the phone has a ‘de-tangler'. This device sometimes goes bad. It is not issued by MCPS.
Check that the ringer is on, or that the ringer is turned up. On LCD phones check to see if the music background is active, LCD says “MUSIC”(even if this feature does not work on your phone), and “CLR” it.
Check to see if any of the cords are frayed or loose. Until we can send a technician on site, dial the weather number and “busy” out the line so that the calls go to another line. Weather number is 301-936-1212.
Check to see if the phone is plugged into the correct jack. Sometimes phones are moved because of cleaning or waxing and they are not placed exactly back to their original location. Sometimes phone cords are plugged into computer data jacks. If you have the option to plug in another phone, and it works, then the actual phone is defective and needs to be repaired/replaced. If another phone does not work, it may be the line and TSU will have to issue a repair ticket to Verizon.
