(6) Cautions during operation
(5) WHISPER switch operation
(a) Periodically confirm with the cabin controller that the room temperature is maintained at
the setting temperature.
(b) When running the freezing unit while the vehicle is parked, select a well-ventilated place
that is not subject to direct sunlight.
(c) The monitor display and digital display of the cabin controller may flicker due to illegal
radio noise output from vehicles. In this case, stop the refrigeration unit once, restart
operation, and confirm the state.
(d) Do not allow water, coffee or juice, etc., contact the cabin controller. The controller could
be damaged.
Stop operation if an abnormal state occurs. Continuing operation in an abnormal state could
lead to electric shocks or fires, etc.

Operation
WARNING
WHISPER switch
Slow speed operation display
Note: The running noise is suppressed but the refrigerating capacity also drops. Therefore, it will take
more time until the room temperature reaches the set temperature.
If any noise is annoying at night or at the residential area since the sub-engine runs at a high speed,
press this switch, and it will be forced to run at a low speed, thus suppressing the running noise. It will
return, if it press once again. <This function is not equipped on TNW4E.>
