IWATSU Telephone System

Changing the Time on the IWATSU Telephone System- ADIX/ECS  (if your ECS system was installed within the last 6 months, the time change on your ‘phone’ system should be automatic)

The below instructions change the clock on the telephone system only.  The time should be changed either at the end of the business day on Friday, or first thing Monday morning.

1.   From an attendant phone  (this is usually the main answering phone or receptionist)

2.   Press  [SPKR], or lift the handset (You should hear ICM dial tone, not outside dial tone.)
If you hear outside dial tone or no dial tone at all press the Intercom (ICM) button then proceed to step 3.

3.   Press [FEAT] + [6] [4]   (the FEAT button is next to the 7 on the dial pad, above or below the TRAN button) 

4.   Enter the current time of day using the 24-hour clock format  (if 8:05am, enter 0805 -- if 5:05pm, enter 1705) 

5.   Press [SPKR]  or hang up 

Note:  You can determine if your phone is an attendant phone by pressing the FEAT button then dialing 99  (with the phone on hook).  If the extension number shown on the top right of the display has a small “s” behind it, then it is an attendant phone.
