Storing Batteries

3.10.1 Storing Batteries

Long term battery storage is not recommended. If storage is necessary:
• Always try to use a 'first-in first-out' approach to minimize storage time.
• Lithium-Ion batteries age much faster at elevated temperatures. Store bat-
teries at temperatures between 0° C and 20°C.
• Always charge batteries to 40 to 60% before storing them. Batteries can be
damaged by an over-discharge phenomenon that occurs when an empty
battery is stored for a long period of time such that the cell voltage drops
below a lower limit.
• To minimize storage degradation, recharge stored batteries to 40 to 60%
every 4 or 6 months to prevent over-discharge damage.
• A 'never used' Li-Ion battery that has been stored for 3 years may have
limited or no useful life remaining once put into service. Think of batteries
as perishable goods.

3.11 Monitoring The Network Connection

If your hand-held is equipped with a wireless LAN radio, it will typically associate
with the nearest access point. The radio signal quality meter in the taskbar indicates
the relative strength of the communication link.
To access the radio signal icon:
• Tap on the radio icon in the taskbar to display the wireless statistics
dialog box.
To access the radio signal icon using the keyboard:
• Press <BLUE> <0> to display the Start Menu.
• Highlight Shortcuts and then choose System Tray from the sub-menu.
• Use the <LEFT> and <RIGHT> arrow keys to highlight the radio signal
icon in the taskbar.
• Press <ENTER> to display the Wireless Statistics dialog box.
Note: Moving in and out of the radio coverage area can have varying effects on
a network session. At times, you may need to renew your connection by
logging in again.
