Features/Before using
What is KDTC730
KDTC730 is a communication terminal which is mounted on a vehicle to form a system
together with server application software on the base station side and used to control
movement of the vehicle and monitor it from a remote place.
Features
● KDTC730 uses satellite communications, so it can communicate everywhere, even in
a mountainous region which the ground communication media cannot cover
satisfactorily. (A communication contract is required in each place where KDTC730
will communicate, however.)
● KDTC730 has GPS function to be able to show the present position of the vehicle
on which it is mounted.
● When KDTC730 is connected to the local network in the vehicle, it can collect the
information of errors in the vehicle, sensors, and etc.
Before using
● Since KDTC730 is a wireless device using radio waves, so it is necessary to obtain
authorization and conform to the laws of the country or territory where the machine
equipped with KDTC730 is being used. It can be used only countries where use of
it is permitted. For the countries where use of KDTC730 is permitted, ask your
Komatsu distributor.
● Always contact your Komatsu distributor when exporting or reselling a vehicle
equipped with KDTC730. Note that the radio communication function of KDTC730 may
be turned off forcibly, when the vehicle is out of the countries or areas where
use of KDTC730 is permitted.
● Before using KDTC730, you are required to take some procedures such as application
for start of use. For details, ask your Komatsu distributor.
● KOMTRAX system uses wireless communications, so it cannot be used inside tunnels,
underground or inside buildings where radio waves cannot be received.
● There is absolutely no need to inspect or operate KDTC730, but if any abnormality
is found, please consult your Komatsu distributor.

Request for correct use
Lithium battery in body of KDTC730
The set operation, time, and other information are backed up by the lithium battery
in the body of KDTC730. Accordingly, if the battery goes dead, the saved data are lost.
The life of the lithium battery is about 5 years (when used at the normal temperature),
although it depends on the using condition. To lengthen the life of the battery, keep
the power cable connected to the battery. The lithium battery power is not consumed
while the power cable is connected. If the battery needs to be replaced, return it
to the manufacture, who will replace it.
Storage
Do not store KDTC730 in a place where it will be exposed to direct sunlight, a place
where the temperature is extremely low or the humidity is high, a place where there
is much corrosive gas. (If it is stored in such a place, its performance and appearance
may be lowered.)
