2-6 Setup and Operation
Battery Status
The left battery icon represents the remaining battery charge when the system is in use as
follows:
n 4 bars signify a 76-100% charge
n 3 bars signify a 51-75% charge
n 2 bars signify a 26-50% charge
n 1 bar signifies a 0-25% charge
As battery power is consumed, the bars disappear. When one solid blinking bar remains,
battery power is almost used up.
NOTE: If two fully charged batteries are in-
stalled, eight bars contained in two battery icons
appear in the display.
Additional battery status symbols include the following:
n If all four bars plus the battery shell are blinking, refresh the battery. To correct
this condition, remove and reinsert the battery, then discharge the battery. See
“Discharging the Battery” later in this section.
n Eight solid blinking bars indicate an abnormal battery status. The battery pack
may not be installed correctly, or is defective.
Function Keys (Fn Keys)
Function keys set specific system parameters and are built into the ROM. When using these
keys, simultaneously press Fn and the corresponding function key. See Table Table Section
2-3 for a list of ROM-based hot keys. ROM-based hot keys change system parameters tem-
porarily. Hot Key functions operate until the system is turned off or reset.
