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 actual life
cycle of a battery pack, such as heat, cold, harsh environmental
conditions and severe drops.
When batteries are stored over six (6) months, some irreversible
deterioration in overall battery quality may occur. Store batteries at half
of full charge in a dry, cool place, removed from the equipment to
prevent loss of capacity, rusting of metallic parts and electrolyte leakage.
When storing batteries for one year or longer, the charge level should be
verified at least once a year and charged to half of full charge.
Replace the battery when a significant loss of run time is detected.
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: http:/

Use with Hearing Aids
When some wireless devices are used near some hearing devices
(hearing aids and cochlear implants), users may detect a buzzing,
humming, or whining noise. Some hearing devices are more immune
than others to this interference noise, and wireless devices also vary in
the amount of interference they generate. In the event of interference
you may want to consult your hearing aid supplier to discuss solutions.
