Re: how to re-program toshiba dkt2020

I have a bit of bad news... your hook switch is bad. It's extremely common for this model phone and every single one will eventually have the problem. Unfortunately the problem starts out intermittently hanging up on callers and people do not understand what is happening. They get frustrated and replace their entire system... This is where most of the used phones come from so most used, even most "refurbished" phones of this type have the problem or will within a few months to a year.


I have repaired many thousands of these phones and it is so common that I am completely sure this is the case. Your phone has progressed to the point where the switch no longer (or rarely) works. Unfortunately the switch continues to go bad even in storage so the phone may have worked to some degree the last time it was used.


Our repair service is listed in the FIXYA repair directory for the USA. If you are interested you can find us by entering your zip code to the repair search box usually on the right edge of the FIXYA screen.


For you problem with stored numbers... the DKT2020 does not have any memory at all. All features, settings and information is stored in the main phone system so any stored numbers, names, etc.. are on your phone system for the port you connected the phone to.

Need to fix date and time onToshiba DKT2020-SD

Depending on the type of system you have powering the 2010,this should take care of it.
Leave the handset on hook, press intercom # 6 5 2, then enter the time of a 24 hour clock, entering 2 digits for the hour, 2 digits for the minutes, and 2 digits for the seconds – enter a leading 0 for any single digit entered,
press Redial,
press Speaker.
This must be done at extension 200 – usually the receptionist phone.
For example, if the time is 2:15 P.M., press intercom # 6 5 2, 1 4 1 5 0 0, Redial Speaker

Change Time on LCD for Toshiba DKT2020


I had the same problem Yesterday.

The way uoi change it, is you have to find the phone with the lowest extension, either 0, 10, 100, 200 etc....

Once you find that phone, leave the handset on the base.

Press Intercome, you should hear the speakerhone activate.

Press #,652

You will see it say ENTER TIME

It's on a 24 hour clock. HHMMSS Format, so it it is 2:05P.M., you would time 1405XX (XX means seconds, obviously not at critical as the touror minute.

Then press REDIAL to submit the change.

These phones do not store information of any kind. All the programming and memory is in the phone system itself.

The phone only works in speakerphone mode because the hook switch is broken. It is a VERY common problem that will happen to all of these Toshiba DKT2000 series phones at some point. The hook switch starts out just disconnecting calls and eventually will not let you use the handset at all. Unfortunately the problem can actually get worse even when the phone is not in use. That is why buying this series used is dangerous. Make sure the seller has replaced the hook switch and try to get a warranty.
