Charging the NiMH Battery
The 950 Detector comes equipped with a universal charger (3M Part No. 457-221-005)
that can be used with electrical systems 100-240 volts and 50/60 Hz. The charger comes
with 4 optional plugs to fit most electrical outlets found throughout the world. To
assemble the charger:
a)
Select the plug for the system you are using.
b)
Slide it onto the charger until it clicks into place.
c)
Ensure it is securely attached to the charger before using it.
d)
To remove the plug, depress the retaining clip.
e)
Slide the plug up and off the charger.
The NiMH battery should be recharged
when the detector alarms and the LCD warns
“LOW BATTERY” or “DEAD BATTERY.” To charge the NiMH battery:
a)
Plug the charger into a suitable AC electrical current outlet.
b)
Plug the charger output into the receptacle near the bottom of the detector.
c)
If the detector is on, you will see moving bars within the battery symbol on
the detector LCD.
d)
If the detector is off, within a few seconds you will see a message
“CHARGING IN PROGRESS” as well as the moving bars within the battery
symbol.
e)
At the bottom of the unit and within the label of the NiMH battery pack, there
is a small LED. This LED indicates the status of the charging process.
a.
Red – continuous, indicates fast charging
b.
Red – flashing, indicates battery conditioning, or a cooling period is in
progress if the battery is too hot. The continuous red LED should
normally follow, however it may take up to one hour.
c.
Green – indicates that the charger is plugged in and that the recharging
cycle is complete.
f)
In addition to the green LED, charging is complete when the LCD battery
symbol is “full” and the outline is flashing.
g)
If the detector is off the LCD will also display a message indicating that
charging is complete.
IMPORTANT: Disconnect the NiMH battery charger from the detector
before unplugging it from the wall.
