Power

The unit draws power from either a direct AC connection or its own rechargeable battery. To optimize the system’s use of power, enter the Power Managment Menu in the Setup Menus. (See page 25.)

AC power

We recommend you use the AC adapter whenever possible to provide the unit with a constant supply of power and simultaneously keep the battery charged. (See “Charging/discharging the battery” below for details.) The proper method for connecting the AC power to the unit is shown below:

Battery power

When you first receive the battery, it is installed in the system but not charged. We recommend that you completely charge and discharge the battery twice as soon as possible, as this improves the accuracy of the unit’s battery power gauge and optimizes the battery’s life and performance.

Charging/discharging the battery

The battery must be connected to an AC power source for about 2 and one-half hours to charge completely. The unit can run on a fully charged battery for about 3- 5 hours of normal use before the battery needs recharging. When the battery level gets low, the battery icon in the status display bar blinks. (See page 8.)
