Precautions for Use
Check the camera battery level and number
of exposures remaining before using the TR-
90 (see the camera manual for details). The
timer will continue to operate even when no
pictures can be recorded due to low battery,
lack of film or memory, or lack of space in
the memory buffer (digital cameras only).
Some cameras have an AF activation option
that determines whether the camera will
focus when the shutter-release button is
pressed halfway (see the camera manual for
details). Enable shutter-release button AF-
activation when using the TR90.
Please note that the timer is less accurate
than most watches or household clocks. Caring for the TR90
Do not drop: The product may malfunction
if subjected to strong shocks or vibration.
Keep dry: This product is not waterproof
and may malfunction if immersed in water
or exposed to high levels of humidity.
Rusting of the internal mechanism can
cause irreparable damage.
Avoid sudden changes in temperature:
Sudden changes in temperature, such
as occur when entering or leaving a
heated building on a cold day, can cause
condensation inside the device. To prevent

17
condensation, place the device in a carrying
case or a plastic bag before exposing it to
sudden changes in temperature.
Keep away from strong magnetic fields:
Strong static charges or the electromagnetic
fields produced by equipment such as radio
transmitters could interfere with the device.
A note on electronically-controlled devices:
In extremely rare instances, unusual
characters may appear in the display panel
and the device may stop functioning. In
most cases, this phenomenon is caused
by a strong external static charge. Turn the
camera off, disconnect the TR90, remove
the batteries, and then replace them once
the display panel has turned off . Caution
is required when handling the batteries,
which may be hot from use. In the event of
continued malfunction, contact your retailer
or AODELAN.
The display panel: LCD displays tend to
darken at high temperatures and exhibit
slower response times at low temperatures.
This does not indicate a malfunction.
