IF USING ALKALINE BATTERIES - PREVENT BATTERY LEAKAGE!
PT2X sensors are typically shipped with lithium batteries. If, however, you are
using alkaline batteries, be aware that under some circumstances alkaline
batteries can leak, causing damage to the sensor. To prevent leakage, the
following is recommended. (Does not apply to lithium batteries.)
• Change the batteries at least every 18 months.
• If the sensor will not be deployed for 3 months or more, remove the
batteries.
