Cannot get the time and date to change
When I put in 402 the next line that comes up is
How do I get to phy000 log000
To find the Correct Telephone:
Most often this will be the lowest extension number; i.e. 10 or 200.
The port is port 000 and can be verified by following the procedure listed here:
Press the INTERCOM button and dial # (pound) 402.
The display on the telephone should read:
PHY=000 LOG=000 (Lift and replace the handset to restore the display)
Going by this, it would seem there is only one phone you can do this on, and the one you are currently trying is the wrong one. I'm unsure of your set up, but try finding
PHY=000 LOG=000 (a different phone if PHY=004 LOG=004 is the one you are using)
