• Do not allow any abrasive material to touch the window.
• Remove any dirt particles with a damp cloth.
• Wipe the window using a tissue moistened with ammonia/water.
• Do not spray water or other cleaning liquids directly into the window.
Cradle
• Do not pour, spray, or spill any liquid on the cradle.
Battery Information
Symbol rechargeable battery packs are designed and constructed to the highest standards within the industry. However, there are
limitations to how long a battery can operate or be stored before needing replacement. Many factors affect the life of a battery pack
such as heat, cold, customer usage profiles, age and severe drops.
When batteries are stored over a year, battery cell manufacturers advise that some irreversible deterioration in overall battery quality
may occur. To minimize this loss, they recommend storing batteries half charged in a dry, cool place between 41° F and 77° F (5° C
and 25° C), the cooler the better, and removed from the equipment to prevent the loss of capacity. Batteries should be charged to half
capacity at least once a year. If an electrolyte leakage is observed, avoid any contact with the affected area and properly dispose of
the battery.
Replace the battery when a significant loss of run time is detected. Batteries must be charged within the 32° F to 104° F (0° C to
40°C) temperature range.
The standard warranty period for all Symbol batteries is 30 days, regardless if the battery was purchased separately or included as
part of the mobile computer. For more information on Symbol batteries, please visit:
