vibration, dust or high moisture.  
When storage and usage temperatures are widely different, leave the  
instrument in the case until it can adjust to the surrounding temperature.  
6
The detector (option) may react to the Laser beam and further react to  
the Fluorescent lamp, Site lamp, modulated light or an electric wave  
(in or near the airport etc.) and so correct measurement is sometimes not  
performed near these places. In these cases, please measure again after  
stopping or cutting these modulated light or wave etc.  
The instrument should be transported or carried carefully to avoid  
impact or vibration.  
7
The instrument should be stored in the carrying case and packed with  
cushioning material and handled with care as Fragile.  
Check the check and adjustment of the datumpoint’of page 35 in this  
manual and be sure to check to see if error exists before the instrument  
is used. After the instrument has been stored a long time or it has  
suffered an impact or vibration, be sure to check to see if trouble exists  
before use. If any trouble exists, adjust or have it repaired.  
8
Be sure to observe the items in the instruction manual for proper use  
of the instrument.  
Please replace attached batteries with new ones before you work  
because their voltage may be low.
