3.0 MAINTENANCE
3.1 Battery Charging
When the “BattLow” message is displayed (refer to Section 2.11), the
monitor must be recharged using the supplied battery charger.
Important! The battery has a long shelf life, but it is recom-
mended that the battery be recharged once a month if left
unused. Batteries that have not been charged for several
months should be given at least two charge/discharge cycles
before using the monitor.
As with all rechargeable batteries, there are guidelines that should be
observed: The battery should normally be charged at room temperature.
Charging at temperatures below 54 °F (12 °C) should be avoided since
this may cause a false indication of when the battery is charged, and
could also damage the battery.
Before beginning the charging process, first ensure that the monitor is
switched OFF. Next, plug the supplied charger into an appropriate AC
wall socket (an optional 12 VDC in-car charger is also available). Then
plug the charger’s output connector into the monitor’s charging socket
(Figure 1, Item I).
The word “CHARGING” appears while the battery is being charged.
Charging time is approximately 2 hours.
Note: If the battery is deeply discharged, the display will
remain blank for a few minutes before the battery begins
charging.
Once the battery is fully recharged, the monitor will emit a beeping tone
for 30 seconds and display the word “CHARGED.” At this time, unplug
the charger and remove its output connector from the monitor.
Important! After charging, you must wait at least 30 minutes
before using the monitor to ensure best accuracy.
