NOTE:
Once a new Battery Pack is installed, it is perfectly normal to get a reading of
3.2 to 3.3 V. This is due to the fact that the WT Series Transmitters take battery level
while it is under load, providing a reliable method of monitoring battery health.
Using the RF Timeout and RF Refresh tags along with battery voltage for monitoring
device and RF communication health is strongly recommended.
If a new Battery Pack has been kept under storage or initially installed, battery level
may need to be read a couple of times to ensure a stable accurate reading.
Replace Battery if reading is less than 2.9 V.
