Maintenance and Inspection

Battery Operation

CAUTION: Before first use and before storing this monitor, fully charge battery.
!
CAUTION: If not continuous use, fully charge battery at six-month intervals.
!
LifeSense is designed to operate continuously when connected to a power outlet or on battery
power for approximately 8 hours. When LifeSense is disconnected from the outlet and is ON, it
automatically runs on battery.

Charging the Battery

CAUTION: Do not charge Li-Ion batteries at a temperature of 0 °C (32 °F) or less as
!
this may result in significantly reduced battery life.
The battery is rechargeable and charges itself whenever the monitor is connected to a power
outlet, even when the monitor is turned off. The green indicator
monitor indicates the battery is charging.
Always connect LifeSense to an outlet whenever it is not in use. Recharging a fully depleted
battery takes approximately 17 hours. To maximize battery capacity for monitoring, you can use
this rule: 1 hour of monitoring needs approximately 2 hours of charging time.

Checking Battery Capacity

The touch panel display shows a battery symbol indicating battery capacity. Approximate battery
capacity is defined by the battery symbols below:
A filled battery symbol indicates the monitor can be used for approximately 8 hours.
A depleted battery symbol indicates the battery has run out of power and needs
recharging immediately.
To check the battery's capacity, time how long a fully charged battery is able to power the device.
When a fully charged battery only provides approximately 4 hours of operation, it needs to be
replaced. Contact Nonin Technical Service for battery replacement.

Battery Message

LifeSense displays BATT LOW when the battery is almost depleted. This gives the operator
approximately 20 minutes of use, or time to plug in the monitor before it switches itself off.
