Battery Operation and Maintenance
3.1
Overview
3.1.1
The Radical-7 Handheld includes a 2.0 Amp-hr Nickel Metal
Hydride (NiMH) battery. The Radical-7 Docking Station may
include the optional 6.5 Amp/hr NiMH battery.
3.1.2
Before using the Radical-7 as a handheld or transport
monitor, the Handheld battery and the optional Docking
Station battery need to be fully charged.
3.2
Battery Charging
3.2.1
To charge the battery(s), attach the Handheld unit to the
Docking Station.
3.2.2
Ensure that AC power is attached to the Docking Station.
Note: Some older units are configured with an AC power switch. Turn the AC
power switch to the ‘I’ position.
3.2.3
The battery charging LED indicator(s) on the Docking Station
will initially flash, then remain illuminated while the battery(s)
is (are) charging. A prolonged flashing battery charging LED
indicates that the internal battery temperature exceeds
recommended operating conditions for proper battery
charging. Proper battery charging will proceed when the
temperature returns to recommended operating conditions.
3.2.4
The Handheld battery requires approximately 2 to 3 hours
for charging. The optional Docking Station battery requires
approximately 6 hours for charging.
3.2.5
When the battery charging LED indicators turn off, additional
trickle charging may occur to complete charging. Although
battery charging can occur while the Handheld is docked
and powered on, most efficient charge times are achieved
with the Handheld unit turned off.
3.2.6
It is advisable to completely discharge and fully recharge the
batteries periodically to maintain optimum battery health.
Refer to the Battery Deep Discharge function as described in
the Radical-7 Operators Manual, Section 4, Service.
