4-5-2. Charging performance
When the voltage of the lithium-ion cell drops below the lower operating limit (approx. 1.8 V), the cell can
be recharged under the following conditions:
-200 lx: It takes approx. 4 hours until the cell can restart the sensor. It takes approx. 30 hours until the
cell voltage reaches 2.3 V.
-400 lx: It takes approx. 2 hours until the cell can restart the sensor. It takes approx. 15 hours until the
cell voltage reaches 2.3 V.
-It takes more than 150 hours under 1500 lx for the cell to be charged fully (approx. 2.7 V).
●Important: Set the sensor switch to OFF while charging.
The above hours are calculated assuming that the sensor switch is set to OFF. Once the voltage has
reached the lower operating limit, the battery cannot be sufficiently charged with the switch set to ON. (With
the switch set to ON, it would take more than five hours under 800 lx until the cell can restart the sensor.)

- 14 -
4-5-3. Operating time in dark places
The sensor is designed to last for the following periods in complete darkness:
Approx. 4 days when the initial voltage is 2.3 V
Approx. 13 days when the initial voltage is 2.4 V
Approx. a month or longer when the initial voltage is 2.7 V (full)
*The operating time depends on the settings, including sensing intervals and signal intensity.
*The above operating time is calculated assuming a 300 sec sensing interval, 6 dB signal intensity, and
3 consecutive transmissions.
