BATTERY REPLACEMENT
Turn the device over and remove the battery compartment cover us-
ing a flat tip screwdriver. The fastener requires only minimal pressure
and 1/4 turn counter clockwise. Remove the battery and pull up on the
three pin connector. This connector is keyed to ensure one way instal-
lation.
Before installing the new battery, ensure the power connector is at-
tached to the circuit board. Once the battery jack is connected, lay the
battery in it’s berth, then replace the battery compartment cover. Again
the screw requires minimal pressure and only 1/4 turn clockwise.
BATTERY RECHARGING
The MGD-2002 comes equipped with the jacks and adapters neces-
sary to recharge your unit either back at the office or while working in
the field. Refer to page #18 for a list of items that comes standard with
this device.
To charge this device using the universal power supply, simply plug
in the universal AC power supply to any standard wall outlet (first) and
then plug in the DC output plug to the device (Second). The internal
software will detect the presence of the charger and will turn off the
detection capability while the unit is in charge.
To charge this device using the standard 12VDC auto adapter, simply
plug the auto adapter into the cigarette lighter jack (first) and then the
output jack into the device (Second). Again, the internal software will
detect the presence of the charger and will turn off the detection capa-
bility while the unit is in charge.
The Nickel Metal Hydride (NiMh) battery is equipped with a tempera-
ture sensing element to ensure the battery will not over heat and ex-
plode during the charge cycle. Should the ambient temperature be too
hot, the sensor may cause the recharge circuitry to shut off prema-
turely. As such, it’s highly recommended that this unit be charged away
from any heat sources.
Although NiMh batteries are some of the best rechargeable batteries
on the market today, there are still some inherent draw backs with their
use. One such issue is that even if the device is unused for an extended
period of time, these batteries lose 40% of their charge during the first
month and 20% every month after that. Thus it’s highly recommended
that the unit be recharged before use.
