Getting the most out of the battery pack
How long the PTC operates on a fully charged battery
pack depends on
• whether you are using the hard disk drive, the
PCMCIA slot(s), or the screen’s backlight;
• whether your PTC is using the optional laser
scanner module;
• whether your PTC is spending a lot of time
communicating through its radio or IrDA port;
• the number of times that the battery pack has
previously been recharged; and
• what the surrounding temperature is.
Maximizing operating time
You can maximize the support time of a charged
battery pack by controlling how you use your PTC.
Here are some tips:
• Keep the battery pack at room temperature. The
colder a battery pack becomes, the less capacity it
has. You may see a decline in capacity below 32
°
F
(0
°
C).
• Reduce the screen’s contrast or turn the backlight
off.
• Keep radio use to a minimum.
Symbol recommends cleaning the
contacts using isopropyl alcohol or a
battery contact cleaner. • Keep the battery pack contacts and the contacts
on the PTC clean.
