ter”, “working hours”, “fuel consumption”.

ment of our products and service, etc.

WARNING
• Never disassemble, repair, modify, or move the communications terminal, antenna, or cables. This
may cause failure or fire on the KOMTRAX equipment or the machine itself. (Your Komatsu distribu-
tor will perform removal and installation of KOMTRAX.)
• For anyone wearing a pacemaker, make sure that the communications antenna is at least 22 cm
from the pacemaker. The radio waves may have an adverse effect on the operation of the pacemak-
er.
• Near the blasting jobsite, there may be a danger of unexpected explosion due to use of interactive
wireless communication device of KOMTRAX and resulting serious personal injury or death. Make
sure to operate the machine away from the blasting jobsite.
If you have to operate the machine within 12 m from the blasting jobsite or the remote-controlled
blasting device, the power supply cable of KOMTRAX must be disconnected in advance. If you want
to do this, ask your Komatsu distributor for disconnecting power supply cable of KOMTRAX.
Also, if there are any requirements or regulations of the territory or country where the machine
equipped with this device is used, such requirements or regulations have a priority than this warn-
ing.
When checking for compliance with regulations, refer to the following KOMTRAX equipment satel-
lite communication specifications.
Rated transmit power: 5 to 10 W
Transmit frequency:148 to 150 MHz
PRECAUTIONS FOR USING KOMTRAX
• Even when the key in the starting switch of the KOMTRAX system is at OFF position, a small amount of
electric power is consumed.
It is recommended to run the engine periodically to charge the battery. When storing the machine for a long
period, see “PRECAUTIONS FOR LONG-TERM STORAGE (3-242)”.
• When using the battery disconnect switch, turn the starting switch to OFF position and, after checking that
the system operating lamp goes out, set the battery disconnect switch key to OFF position and pull it out.
When the battery disconnect switch is turned to OFF position, it is possible to prevent power consumption
of the battery, but the functions of KOMTRAX stop at the same time.
For operation of the battery disconnect switch, see “BATTERY DISCONNECT SWITCH (3-126)”.
• Contact your Komatsu distributor before installing a top guard or other attachment that covers the cab roof.
REMARK
The KOMTRAX device uses wireless communications, so it cannot be used inside tunnels, underground, inside
buildings, or in mountain areas where radio waves cannot be received. Even when the machine is outside, it
cannot be used in areas where the radio signal is weak or in areas outside the wireless communication service
area.
