ASSEMBLY PROCEDURE
2.1 Assembling the instrument body
To avoid the risk of electric shock, disconnect the cable from the power supply before assembling the instrument. Never plug in the power cable before assembly.
WARNING
Always install the instrument on a fixed, stable surface, to prevent damage or injury.
CAUTION
CAUTION
Note:
The instrument should always be carried by two people, both holding the bottom of the instrument. Attempting to carry the instrument alone could result in backache or other injury. Attempting to carry the instrument without holding it at the bottom could result in injury or damage.
Since the upper part and lower part of the instrument are connected only by the power cable, take them out together so they do not separate from each other.
