Day Service refers to any configurations that you have programmed the
DSI to perform.
However, sometimes, different service is required at night. For this
reason the DSI provides a Night Service option. When the DSI is
operating on Night Service mode, all lines on the station and the add-on
module will ring whenever there is an incoming call.
The DSI will retain all configuration programming even if there is a
power failure or you unplug it. When power is restored, you may
continue to use your DSI as before.
You can attach the DSI and either the CTA-369 or CRI-376 to your MBS.
For more information about these models refer to the last page of this
guide.
To program the DSI with the CTA/CRI:
1. Apply power to the DSI and program it using the dial pad of your
MBS.
2. Disconnect power to the DSI.
3. Apply power to the CTA/CRI and program it using the dial pad of
your MBS.
4. Reapply power to the DSI.
