STRAP OPTION SELECTION
Modem configuration is controlled by front panel pushbuttons and the
LCD, AT or V.25 bis commands, and hardware option straps located on
the pc board. Normally straps do not have to be changed. If a change is
required, remote the modem cover to access the option straps. The strap
diagrams on the following pages indicate the factory settings.
Removing the Cover
Warning
Disconnect ac power before removing the cover. Although
dangerous voltage levels are not exposed, disconnecting
power ensures an electrical shock hazard is not present.
Place the unit on its side on a flat surface. To disengage the lock prong
from the lock clip insert a medium size flat screwdriver blade in one of
the latch slots. DO NOT PUSH the screwdriver but lightly pry the
handle away from the unit as illustrated in Figure C-1. Assist removal
by pushing the cover from the chassis with your fingers on the unit rear
edges. Repeat this procedure with the remaining three latch slots.
