NEC Dterm80 Our phones are stuck on night mode. Suggestions on how to get them off?

All of my NEC Dterms have problems I have been replacing them one by one, with my vendor. Today I called my vendor to ask them for 5 more replacements. (this would now make the last of all my original phones to be replaced) To my surprise they told me I can no longer exchange my phones as the warranty is over. GEEZZZ! NEC needs to take responsibility on this matter as this is clearly a manufacturing defect, (phones are dated 2007)

To here ring types hit speaker then 711, then 1 for internal rings (select 2 for outside ring selection) then 1-8 the ring type.
To set ring type hit speaker then 720 (follow all the steps above).

Feature 69 feature

Do a search for a plantronics headset. All of theirs work well with NEC

press feature 80 feature

I have the 8 button phone and if you hook up your headset the right way you just have to press the line/feature access key all the way to the right instead of picking up the receiver. Keep the headset on all the time and just press that button to answer or hang up the calls. It works great! ( I have the Dterm80 telephone)

Ok. You will have to find someone who has access to system manager, or has system manager rights for their mailbox.

They will then be able to select System Manager Options, then Change the Greetings. It will tell you which mode you are in, and ask you if you want to change to Holiday Mode. The responses are 1 for YES and 2 for NO. Say no to Holiday Mode, and then it will go thru Day Mode and then Night Mode, playing each one first then asking if you want to change it.

If you must call in a service order with your phone system vendor, make sure he/she not only assigns someone's box with manager access, but also creates a back-door box with manager access. This way you won't be messing with the original Manager Box. It gets expensive having NEC decipher the Manager's password if it gets changed and no one remembers it.

you must assign ringing in program mode. MB 4-01 day and 4-02 night. if this is an elite or ipk. If its ipk2 or 2000 than MB's are different. ldtsnj.com

Press the "Speaker" button and enter 728 on the key pad. Then enter the correct time in 24 hour format. For example at 2.56 p.m. type 1456. Then press speaker again and you're done
