2. GENERAL RULES FOR THE CORRECT AND SAFE USE OF THE RADIO
CONTROL
For maximum safety when handling the radio control, the user must follow the rules described in this
manual.
Whenever the crane has to be manoeuvred, the radio control operator must be in a place where he
can view the whole manoeuvre being performed. If this is not possible, he should place himself where
he can see as much of the manoeuvre as possible, and coordinate with another person when he
cannot see properly. Never perform a manoeuvre which may be partially uncontrolled.
Do not leave the radio control transmitter on the ground or on metal blocks. If you must do so,
activate the emergency stop (STOP BUTTON) of the radio control and turn the key/switch to the OFF
position or lock the keyboard if it is activated (see the section
Procedure to lock the keyboard
).
At the end of the working day, or if the radio control operator has to leave the radio control, he should
activate the emergency stop (STOP BUTTON) of the radio control, turn the key or selector switch to
the OFF position, place the battery in the charger for recharging and turn off the crane.
Procedure to lock the keyboard
The equipment can have the option of the keyboard lock on the transmitter, by means of a system of
sequential lock/unlock of buttons. This system is similar to the one used to lock telephones.
To lock the keyboard press the start button 5 times in less than 3 seconds, with the STOP BUTTON
pressed. Both leds
and
will light up for 3 seconds.
To unlock the keyboard, repeat the same operation, that is, press the start button 5 times in less than
3 seconds, with the STOP BUTTON pressed. The operation will also be indicated in the same way,
that is, both leds
and
will light up for 3 seconds.
In case the start button is pressed while the keyboard is locked, both leds will blink alternatively.
