Estimating Battery Life
If the Unit is used as a Repeater for wireless communication five minutes
a day, new batteries can be expected to last about six months.
- Battery life varies depending upon the type of battery, the battery performance, the
measuring environment and frequency of use.
Note
- Always use two batteries of the same type.
- Make sure that + and - are in the correct direction.
- Batteries cannot be charged inside the Unit.
- The LED lamp will blink once when usable batteries are installed.
- Leaving alkaline batteries in the unit for a long period of time may cause battery leakage
and corrosion. When using as a backup source, we recommend that you change the
batteries every few years.
