REMOTE CONTROL
OPERATION
WARNING!
• In no event, attempt to disassemble or
modify the Transmitter or Receiver, which
may cause an electrical shock or a fire.
• Avoid to make an impact to the Transmitter
by dropping or hitting. A damaged part of
the enclosure allows water to enter inside
that brings its troubles or failures and cause
a serious hazard, such as malfunction or
electrical shock.
In such event of dropping and damage,
send the Transmitter to us or our sales
service agency.
• In no event, water-wash the Transmitter or
Receiver; that allows water to enter inside
and brings its troubles or failures and cause
a serious hazard, such as malfunction or
electrical shock.
• Both remote control operation and manual
operation at a time are not allowed.
That may cause the un-expected behavior of
the Crane and results a serious hazard. The
Crane must be operated by only in either
method. (Manual operation is not available,
when the remote control is active.)
• Prior to start the remote control operations,
always conduct inspections of both the
Transmitter and Receiver, in accordance
with "REMOTE CONTROL SYSTEM
VERIFICATIONS" on page 4-106.
Cautions Before Operation
1. So that dropping the Transmitter is
prevented, hook one end of the hook belt
(16) to the Transmitter and attach another
end to the operator’s waist belt, or such.

2. Always conduct inspections of both the
Transmitter and Receiver, in accordance
with "REMOTE CONTROL SYSTEM
VERIFICATIONS" on page 4-106.
3. Make sure that the receptacles (14) in the
both ends of the connection cable are
secured to both the Transmitter and
Receiver, respectively.

NOTICE:
• When it is required to change the initial values
of settings such as the contrast of the
Transmitter LCD screen, the light, or the OFF
timer, once switch to "A MODE" for
adjustment.
• In the event that the remote control operation is
discontinued for the length of the "Auto shut -
OFF time" or more, during the crane operation,
the Transmitter power will be automatically cut.
To resume the remote control operation, turn
ON the Transmitter and set each items for the
operation mode, again.
Operation in Outrigger Mode
WARNING!
• Check smooth and correct actions of each
operation lever of the Transmitter, and they
smoothly return to each neutral position
when the finger is released.
• Each operation lever of the Transmitter will
be blocked by its stopper when it is moved
full. When it is blocked, do not attempt to
push more, otherwise it may damage the
Transmitter to cause its fault and results a
serious accident.
