No Shock to the Transmitter
• During the Transmitter operations, always use
a hook belt (1) to prevent the unexpected drop
of it.
Fig. 4-227
• Always avoid an impact on the Transmitter,
such as hitting it to any object.
It may result a damage to the enclosure or
internal components which may cause a failure
or malfunction and brings electrical shock or
other serious hazard.
Fig. 4-228
• In the event of such damages, send us or to
our agents for services.
Use of such a damaged Transmitter will result
in miss-operation and extend to electrical shock
or other serious hazard.
Precaution for Operations in Cold
Seasons
• Avoid the use of the Transmitter in a condition
where the ambient temperature makes sudden
change or becomes extremely low (-10°C or
below) or cold air directly blows
Sudden change in temperature may cause dew
formation inside the Transmitter and which
causes failure or malfunction and leads to a
serious hazard.

• In the winter times, allow sufficient idling prior
to starting crane operations. In the winter, due
to the low temperature, hydraulic fluid has
higher viscosity. Such condition may result in a
delay of functions in crane operations.
• Keep the Transmitter away from conditions as
below for its storage, where the Transmitter
enclosure may deform or discolour, or internal
components may be damaged to bring
malfunctions and a serious hazard:
• Extremely low temperature (-20°C or below) or
direct cold air blow.
• Direct sun ray.

• Adjacent to warm air outlets of vehicles.
• Adjacent to housing heating system.
• High humidity.
Precautions for Handling of Connection
Cable
Do not attempt to hang the Transmitter by the
connection cable and fling it around, or bend the
cable or thread on it. Such poor handling will
damage the internal wires or produce other
failures.
