Follow these steps to upgrade your system’s software with a PC card:
CAUTION:
Before starting, verify that you have batteries installed in the processor
module by viewing the display of the telephone at extension 10.
1 If you have a 5-slot carrier, move the carrier’s On/Off switch to the “Off”
position (“O”).
2 For all types of installations, disconnect the power cord from the wall outlet.
3 If you do not have a 5-slot carrier, go to Step 4.
If you have a 5-slot carrier:
a Loosen the thumb screw at the bottom of the carrier cover.
b Rotate the carrier cover to disengage the tabs at the top of the modules
from the openings on the top of the carrier cover.
CAUTION:
Remove all other PC Cards from the processor before initiating an upgrade.
4 To insert the PC Card, hold it with the label facing to the right, and slide it
gently into either PC Card slot on the processor module. When inserted
properly, the PC Card projects about 1-5/8 inch (4 cm) from the module.
