Disassembly
Procedures
The T 1900ff 1900C
has
two basic types
of
cable connectors:
o Pressure Plate Connectors
o Normal Pin Connectors
To disconnect a pressure plate connector, lift up the tabs on either side
of
the connector's
plastic pressure plate and slide the cable out
of
the connector. To connect the cable to a
pressure plate connector, make sure the pressure plate
is
fully
lifted and slide the cable into the
connector. Secure the cable
in
place by pushing the sides
of
the pressure plate down so the
plate
is
flush
with the sides
of
the connector. Gently
pull
on the cable to make sure the cable
is
secure.
If
you
pull
out the connector, connect it again making sure the connector's pressure
plate
is
fully
lifted when you insert the cable.
Standard pin connectors are used with
aU
other cables. These connectors can be connected
and disconnected by
simply
pulling them apart or pushing them together.
