Before Using the DTR-10.5
—Continued
The option boards should be installed in their individual
designated slots. Installing the option board a different
slot may cause failure.
Installing the Option Boards
1
Turn off the power and unplug the power
cord both from the DTR-10.5 and electrical
outlet.
Be sure to turn off the power of the DTR-10.5.
Inserting or removing an option board with the
DTR-10.5 turned on may cause failure.
2
Take the option board out from the pack-
age carefully.
The option board incorporates many components,
terminals and connectors along with solderings
on its surface. Touching the board with your fin-
gers may cause failure or damage from static elec-
tricity, incorrect contact and so on. When
handling the board, be sure to hold the outer part
or panel section of the board without touching the
board surface.
3
Check the alphabet letter on the option
board.
The alphabet letter is printed at the top left corner
of the panel section.
4
Remove the sub-panel with the same
alphabet letter as your option board from
the back of the DTR-10.5.
Use the supplied Allen wrench to loosen the screw
gradually, while holding the sub-panel so that the
panel will not drop down.

The sub-panels are fixed to the DTR-10.5 with
two screws at the top and bottom, while the panel
that covers slots [H] and [I] is fixed with four
screws at the top and bottom. Keep the removed
screws for fixing the option board.
5
Insert the option board along the rail
softly. When the board comes to the posi-
tion where it stops but does not cover the
slot completely, push the board forward a
little bit more strongly.
6
Fix the option board firmly to the DTR-10.5
using the removed screws.
Be sure to tighten the screws firmly to the
DTR-10.5. If the screws are loose, contact failures
for ground or signal wires may occur at the section
between the DTR-10.5’s slot terminal and the
option board, which may cause the DTR-10.5 or
board to fail.
