13. Notes
(1) Do not store or operate the meter in high temperature or
humidity.
(2) Remove the battery when the meter is to be stored for long
periods of time to avoid battery leakage.

measurement. Use the supplied windscreen to cover the
microphone when appliance.

after power the meter on, which indicates the battery power is low,
replace the meter's battery.
