1. Precautions 

1.1 

After  unpacking  the  carton,  check  the  parts  against  the  packing  list  first.  If  there  is  any 

difference, contact the sales department to protect your benefit. 

1.2 

When carrying and unpacking the carton, pay attention that the arrow on the carton shall be at 

upward position. Handle the instrument with care to prevent it from being damaged.   

1.3 

The instrument shall be used and kept in a clean and dry place with constant temperature in 

order to ensure the lifetime of the component in the instrument. Before using the instrument, 

make sure to step down the brake on the foot wheel to prevent the instrument from sliding to 

avoid accident. When moving the instrument in the room, it is recommended to push it at the 

lower part to prevent the instrument from being upset and damaged.   

1.4 

Do not touch the surface of the lens and prism with hand or hard objects.   

1.5 

When the LED bulb is broken and has to be replaced, make sure that the power is off and the 

bulb is fully cool down in order to prevent your finger from being hurt. Never touch the glass 

surface of the illumination bulb (LED bulb) with your finger directly. If the bulb surface is found 

oily and dirty, it shall be cleaned with flannelette soaked with alcohol before usage.   

1.6 

The counterweight of the base of the instrument is limited. When the arm is stretched, never 

press  the  instrument  with  strong  force.  Otherwise,  the  instrument  can  go  down  to  get  the 

operator or the instrument itself damaged.   

1.7 

Before using the instrument, make sure the connecting parts are fastened or adjusted to right 

position to avoid accident caused by the failure of the parts.   

1.8 

Never move any part of the instrument with strong force. Adjustment shall be done according 

to the instruction, especially for the operation handle, it shall not be turned with over force to 

prevent it from impacting the arm to get the components damaged.   

1.9 

Power  shall  be  switched  off  after  using  the  instrument.  After  use,  the  instrument  shall  be 

cleaned and covered with plastic cover to prevent dust.
