SYSTEM OPERATION
WARNING! Electrical Shock Hazard. Do not
disassemble or modify the transmitter or
receiver. Damage to the components may
result in electrical failure.
WARNING! Electrical Shock Hazard. Do not
use sharp objects or tools to operate the
transmitter. A sharp object or tool may
damage the transmitter, allowing water to
enter it and resulting in internal component
damage and/or electrical failure.
WARNING! Sudden Movement Hazard. Always
keep the transmitter clean and free of oil and
mud. A slippery or dirty transmitter may cause
an operator error.
WARNING! Electrical Shock Hazard. Do not
allow water to enter the transmitter. Only use a
damp cloth with detergent to clean the
transmitter. Damage to the transmitter may
result if water is allowed to enter it, resulting
in internal component damage and/or
electrical failure.
WARNING! Electrical Shock Hazard. Do not
use the transmitter if its case is damaged. Do
not drop the transmitter or allow the case to
become damaged. A damaged case may
cause internal component damage and/or
electrical failure.
WARNING! Sudden Movement Hazard. Do not
use the transmitter if its case is damaged. A
damaged transmitter case may cause operator
error.
WARNING! Sudden Movement Hazard. Do not
use both the remote control and manual
controls to operate the crane at the same time.
Only one method of control must be used at a
time to operate the crane.
Before operating the radio remote control system,
verify proper operation of the transmitter and
receiver. See “RADIO REMOTE CONTROL
SYSTEM VERIFICATIONS” on page 4-104.

NOTICE:
• If the battery for the transmitter runs low,
recharge the battery or replace the battery with a
charged battery.
• In the case of the radio remote control system,
radio waves may not be received even at close
range due to jamming or depending on reflection
conditions in the vicinity.
• Operate as close to the Receiver antenna as
possible.
• In crane operation, when the transmitter has not
been operated for a certain period of time after
the last operation, it will be automatically turned
“OFF”. When using the transmitter again, first
turn on the transmitter power.
