Installing The Phototimer; Overview; Notes - Canon CXDI-40G COMPACT Service Manual

6. Installing the Phototimer

6.1 Overview

Obtain a phototimer and fixture piece from a distributor, and install it in the Bucky unit, stand or
table.

6.2 Notes

1) Cable routing
The routing for the Bucky unit and table/stand cables connected to the phototimer are based on
the specifications of the respective phototimer, but they must satisfy the conditions below.
Do not forcibly bend, fold over, or pull out the cables, and secure the cables so that no
excessive loads are applied to them in any state.
2) Selecting the phototimer
The recommended phototimers should be structurally identical to the recommended
phototimer models for the CXDI-40E series. Note that quality cannot be guaranteed if
phototimers not listed here are installed.
Obtain a phototimer with suitable light sensor dimensions for installing in the Bucky unit,
stand or table. The table below shows phototimers that are installed in the series 40E imaging
units. Note that other phototimers with identical light sensor dimensions to those in the table
below cannot be installed.
