brightness suitable for most monitoring locations that uses less battery power than brighter settings.
Ensure that the current level of brightness is suitable for your monitoring location.
Charging the Battery
To charge the battery,
Connect the monitor to the external power supply (M8023A).
1
Charge the battery until it is full, the battery LED is green, and the battery power gauge is filled.

In certain situations, where many measurements are in use (plus the recorder), the load on the monitor
may be so high that the battery will not charge. In this case you must reduce the load by removing
measurements, reducing the screen brightness or stopping the recorder. Internal temperature
conditions could also cause the battery to not charge. This is necessary to protect the battery from
damage and does not indicate a malfunction. Keep the monitor at room temperature and move it away
from heat sources or out of direct sunlight. The battery will resume charging when the temperature is
within range again. Note that the battery will charge more quickly when the monitor is switched off.
Storing the Battery
The battery should not remain inside the monitor if it is not used for a longer period of time. Batteries
should be charged to a maximum of 50% for storage. For battery removal or exchange, contact your
service personnel.
