RADIAN™IS 21
The battery located in position A of the battery compartment in
the Radian IS is always discharged first before the system will
switch to the power supplied by the battery located in position
B. Each battery compartment has an associated LED light that
indicates if the battery in that compartment is in use (green
blinking LED). If the battery is not in use, or the battery is
drained, the LED will not illuminate or blink. For more
information see Section 4.3.2, Battery indicator, on Page 39.
*
Note: Before placing a battery into the Radian IS, use your
battery charger to ensure that it is fully charged. The
Radian IS assumes that when you install a battery into the
battery compartment, it is fully charged. If the battery is not
fully charged when inserted, the battery gauge on the front
panel of the Radian IS will report the battery status
incorrectly.
To recharge an internal battery, remove it from within the
Radian IS. Follow the instructions provided with your battery
charger.
If you connect the Radian IS to an external power source such
as a battery or electrical outlet, the external power input must
be terminated (dead battery or power failure) before the Radian
IS will switch to internal battery power.
3.2.3.1 Inserting and removing the battery
When the access door is open, you have unobstructed access to
the internal battery compartments. For a view of the open
access door, see Section 3.2, Access Door, on Page 17.
To insert a battery into the Radian IS, open the access door. Two
compartments are located within the Radian IS for housing
internal batteries. Between the two compartments are two
battery clips that hold the batteries into place within their
compartments. For a view of the battery clips, see Figure 8,
Access door open, on Page 17.
