5. Maintenance
It is important to keep all optical connectors and surfaces free from oil, dirt, or other contamination to ensure proper operation.
Keep using one type of adapter to avoid excess loss from different connectors.
Please use dust-proof cap for protection to avoid being scratched or contaminated when SNP3402 not in operation.
Light interface is sensitive, please carefully plug in and pull out connectors.
Once not using for a long time, please take out the battery.
Notes: Please use lens paper with cleaning liquid for sensor’s surface cleaning, do it in clockwise direction carefully.
6. Trouble-shooting
Description | Probable cause | Method |
Faint LCD display | Battery is inadequate | Change battery |
Switch on but no display | Battery is inadequate /Others | Switch on again/Change battery |
Insensitive display in LCD | Light interface is polluted of broken/Display locked | Check light interface carefully and clean sensor’s interface |
7. Change Battery
If you find battery is not enough while operating it, switch off SNP3402.
