- Page 4 WARNING • While the instrument is operating, be careful not to expose your eyes to the emitting laser beam (red light source). Exposure to a laser beam for a long time may be hazardous to your eyes. (Laser beam: Equivalent to class 2 Laser level) •...
- Page 5 Precautions The instrument should not be stored or used in extreme temperatures or job on a place subject to rapid change of temperature. (Refer to the ambient temperature range) The instrument may not function properly if used out of the ambient temperature range.
- Page 6 Put into the carrying case for storage and place in a dry area not subject to vibration, dust or high moisture. When storage and usage temperatures are widely different, the case should be open whilst it is acclimatising to temperature changes.
- Page 7 The detector ‘optionional’ 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.
- Page 8 The instrument should be stored in the carrying case and packed with cushioning material and handled with care as ‘Fragile’ . Before use the instrument should be checked to ensure it is working correctly. (See section on page 35 of this manual). After the instrument has been stored for a long time or if it has suffered from an impact or vibration the user should check that it is working correctly.
- Page 9 Be sure to observe the items in the instruction manual for proper use of the instrument. Check batteries before use and replace them if their voltage is low.
