Fig. 4-206
• 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.

Precaution for Operations in Cold
Seasons
WARNING!
• Avoid the use of the Transmitter in a
condition where the ambient temperature
makes sudden change or becomes
extremely low (14°F 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 (-4°F or below)
or direct cold air blow.
• Direct sun ray.
