Because of a dead battery (for backup), automatic
updating of date stops.

1) Measurements can be done. Select either one from the

followings and use the TX-20 as it is.

Select [OK].

Reflect the clock on the measurement results. Set the
correct clock again on the displayed clock input screen.
However, the clock you have set again is valid only when
the power is turned on.

Select [CANCEL].

The clock is not reflected correctly on the measurement
results. The clock input screen is not displayed and the
TX-20 is reset at the initial value 2010/1/1.

If this error occurs, the clock function of the main unit is not
kept. Therefore, you need to set the clock each time you
turn on the power. We recommend replacing the battery. For
replacing the battery, ask

your sales representative or local

Canon dealer.

329

The USB device of full-speed specifications was connected
to this product.

1) Record the message code, contents (including error

codes) and then execute [OK].

2) Connection check is necessary. Ask your sales

representative or local Canon dealer to perform the
connection check.
