To install the Mailbox Expansion Card, insert the card in the vertical slot on the
lower front of the voice messaging system module (see Figure 2-3). Make
sure the arrows on the Mailbox Expansion Card label face up and in, as
indicated on the card’s label. Also make sure the card is pushed in all the
way.
Turn the control unit’s power on. The green Power LED should light—if it
does, skip to Step 6. If the green Power LED does not light, power down
the control unit, reseat the voice messaging system module, then power
up the control unit again. If the green Power LED still does not light, call
the Helpline.
Next, the voice messaging system module performs self-diagnostic tests.
The LEDs work as follows:
