4. Insert the AA battery shell into the battery compartment of the
receiver as shown in “To attach the batteries to the GR-5
(Figure 2-12):” on page 2-16.
Surveying while Charging
The user can execute any kind of surveying while charging the
internal batteries attached to the GR-5 without degradation of
performance.
Changing the Batteries while Surveying
It is safe to change a depleted battery with a fully charged one while
surveying (i.e., on the fly) without turning off the receiver. Before
doing this, make sure the other battery has enough charge to power
the receiver while changing the depleted battery. The surveying will
not be disrupted. If needed, repeat this procedure for the second
battery.
Using an Auxiliary Power Source
In addition to the attached batteries, the receiver connects to external
batteries. External batteries allow for continuous use of the receiver in
case the internal batteries become discharged.
To connect the receiver to the charging cradle (Figure 2-15):
The charging cradle with extra batteries hooks onto a tripod or belt
for a convenient power supply for the receiver. The part number for
the receiver-to-charger cradle cable is 14-008072-01 or 14-008072-
02.
While charging, make sure the air temperature is
between +32
o
F (0
o
C) and +113
o
F (+45
o
C). This
is important to prevent serious damage to the
batteries, the receiver or injury to persons.
The batteries in the charging cradle do not charge
the internal/detachable batteries.
The charging cradle is used to power the receiver.
