I'm unable to rename any file in win XP,a message appears "If you change a file name extension,the file may become unusable" Plz help

Go to control panel then go to folder option then click on view tab. On the list you'll find a option named "Hide extensions for known file type". Enable this option and click OK. Now you can rename your files easily.

How do I identify extensions, transfer calls, conference call, change time.

To identify the extensions: if its a display set, press feature 00 and the screen will show the extension number. press feature 00 to exit programming.
If its a non-display set access the intercom and call a display set.The extension number will be displayed on the screen that is recieving the call.

To transfer a call: while your on the call to be transfered, press the transfer button and then the extension number of the person you wish to transfer the call toand hang up.

For a conference call:while on the line with the first caller,press the conf key (the caller will be placed on hold) place a call to your second party when they answer press the conf key again. all 3 parties will be bridged(you + the 2 lines) to get rid of one of the callers press thier line and feature 6 (conference drop)

Changing the time on a Partner system is done on either ext 10 or 11. At one of those ext's press the feature key and "00"
next press the left hand intercom twice
the display should say system programming
enter in "#103"
the display should say system time and the current programmed time
enter the new time in 24 hour format
press feature "00" to logout

M7310: Phone number

Sorry about the delay, I lost your post and could not get back in touch with you... This is a case where a certified Norstar tech will come in handy...
OK - lets get started.... Do you have the programming password to get into the system? Do you have the programming template (piece of paper to guide you thru the proper steps in which button to press?)
If you do lets go: Go to a set, hopefully a bigger set with 2 rows of buttons... -> Feature * * 2 6 6 3 4 4 -> is this is a CIC's/MIC's system it will ask for a password see next step, if this is a BCM it will ask you for a User ID:___ your default ID is 738662 -> Password:___ default is 266344
-> now you will see TERMINALS&SETS... keep hitting the NEXT button off the template till you see SYSTEM PRGRMING... -> now hit the ENTER and press the NEXT key till you see CHANGE DN -> now press ENTER this is were you will type in the old extension number (EX:2331) then type in the new extension number that you want the set to have (EX:5331) -> now hit the RLS button... check to see if the number changed but pressing FEATURE * 0 and pressing the INTERCOM key.
Now there are a few things that you have to remember, the voicemail has not been changed, the new extension needs to be programmed into the TARGETLINE for your DID number to ring at your desk, and if you have your extension as a Busy Lamp Field on the front reception, you have to change that to your new extension by going to the receptionist desk: ->FEATURE * 2, pressing your button, and dialing your new extension. -> now to see what your direct number target line is, press FEATURE * ) and press the button for your direct line... and see what LINE number you have, now get back into the system programming and find LINES and type in the number that you found on your phone (EX:255), press ENTER and press ENTER again you should see TARGET LINE. -> Keep pressing NEXT till you seePRIMESET:___ this has your old extension and press CHANGE and type in your new extension. -> hit the NEXT button and RLS -> your voicemail dial FEATURE 9 8 3 If you have a BCM your default LOG:___ is 738662 but if you have a MIC/CIC's system it will say password: default password is 10020000 for a 4 digit extension, 1020000 for a 3 digit extension. But if this a BCM the default password will be 2 6 6 3 4 4 -> press MBOX -> press CHNG -> your old extension -> you should now see PASSWORD press NEXT and you should see your old extension press CHNG and type in your new extension. Hit the next button after inputting this information, until you get back to the MAILBOX ADMIN and hit RLS.

Voila you are done! Good Luck

Cannot change name ID for each extension, shows old names

Read several on-line manuals and found out another way to access programming trees. It was a confusing mess and was mostly trial and error. The 4 keys under the read out screen are a key factor and knowing how those buttons interact with each other is important. In the process I screwed up regular functions because the password that allows set-up using the feature codes cannot be changed. Not a user friendly set-up at all and the initial manual virtually useless for some needs.
