I need a manual for model LA21937EE2B-A

without phone model - I can give you vague solution but here goes

find apps. in spanish it will be most likely be aplicaciones
find settings could be Ajustes in Spanish
system - Sistema in Spanish
look for Idioma e introduccion in Spanish
then look for idioma in Spanish
change from Espanol to english

Since you didn't give the model of your VTech system, please enter it into the search box at http://www.vtechphones.com/support/general/manuals to download a copy of the manual.

I can download Spanish version MFL47342656

Where from do you download that manual?
Thanks

Intermatic posts manuals in Spanish and English, but not every manual is available.
Here are some choices.

1) Add a comment with timer model number and I'll find manual and post link if manual is available.

2) Go to Intermatic manual page below. Use 'Find' feature on browser (click Edit > Find) to locate model number quickly on page. Manual search takes you to individual manuals or to a product page. When page comes up model numbers show in a vertical row > click model number to view drop-down menu for links to manuals.
Not every manual is available.

3) All else fails, use google translate. I re-wrote and posted GE yard stake manual today using translator. Enter whole sentences into translator > no need to translate word by word anymore.

Here's outdoor GE timer translated from Spanish using google translate:

5) Add a comment and post link where you found Spanish version of manual (as long as it's not a free-manual-with-spyware website) and I'll locate English manual if possible -or- translate manual for you, and post result next day or so.

There are three models: DVD-R150 , D-R150 and DVD-SR150M: I hope your model is one of these.
The english manual for DVD-R150 can be found at:

The english manual for DVD-SR150M can be found at

http://downloadcenter.samsung.com/content/UM/200708/20070821193220921_01452A-SR150M-XEU-ENG-BM.pdf

I took Spanish version and used Google translation tool for parts I needed. Longwinded way of doing it but it works (In a fashion)

interesting! Sure you are not connected to a dedicated Espanol station? I have tried to emulate your problem but cannot succeed I can only recommend you try to tune that channel manually to another number and see if it still does it.

language=idioma
english = ingles
I hope this helps

MANY TIMES, YOU CAN GO RIGHT TO THE MANUFACTURERS WEBSITE AND ENTER IN YOUR MODEL NUMBER AND PRINT THEM RIGHT OFF.

what model of answering machine?...that i need to know!
