Cleaning Detector Ports
Regular cleaning of detectors will help maintain measurement accuracy.
To clean detector ports:
1. Remove the protective cap and adapter (FOA) from the detector.
2. If the detector is dusty, blow dry with compressed air.
3. Being careful not to touch the soft end of the swab, moisten a supplied cleaning
tip with only one drop of isopropyl alcohol.
4. While applying light pressure (to avoid breaking the detector window), gently
rotate the cleaning tip on the detector window.
5. Repeat step 4 with a dry cleaning tip or blow dry with compressed air.
6. Discard the cleaning tips after one use.
Recharging the Battery
The Li-Ion battery will last about 70 hours (power meter) or 50 hours (source in Auto
mode) in normal operation. The charge status is shown on the unit display (lower
left corner).
To recharge the Li-Ion battery:
Connect the unit to a power outlet (or car outlet) using the AC adapter/charger. The
charge cycle will start and end automatically.
Note: While charging, the battery indicator animates continuously. It does not
reflect the actual charge status until charging is complete.
