battery operation and maintenance

The Radical Handheld includes a 1.5 Amp-Hour Nickel Metal Hydride battery. The Radical

Docking Station may include the optional 6.5 Amp-Hour Nickel Metal Hydride battery.

Before using the Radical as a Handheld or transport monitor, the Handheld battery and the

optional Docking Station battery need to be fully charged.

To charge the battery(s), attach the Handheld unit to the Docking Station. Ensure that AC

power is attached to the Docking Station.Turn the AC power switch to the “ l ” position.Verify

that the battery(s) are charging; the battery charging LED indicators on the Docking Station

flash prior to charging and remain illuminated while the battery(s) are charging. A

continuously 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.

The Handheld battery requires approximately 2 to 3 hours for charging. The optional

Docking Station battery requires approximately 6 hours for charging.

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.
