Battery Management and Maintenance
You can maximize the battery life with a little bit of care. Since the batteries are chemical devices, it is
important to keep the electron in it flowing occasionally. If the battery is stored in fully discharged state for a
long period, it could fall into a deep discharge state. On the other hand, if the battery is stored in fully
discharged state for a long period, the total battery capacity may be reduced. Please read the following tips
to maximize the battery life.
1. PDA Settings
Turn off unnecessary functions - Functions such as Wi-Fi, Bluetooth, GPS, etc will drain more power from
the battery. If you rarely use such functions, please turn off to save power. To turn off each function, assist
the main manual.
Reduce brightness of the backlight - Brighter backlight will consume more power. Setting the backlight as
low as possible is another way to save power. To adjust the backlight level, assist the main manual.
Enter suspend mode - Entering suspend (sleep) mode when you are not using PDA can increase the
battery life. To enter suspend mode or to set auto-suspend mode, assist the main manual.
2. Charging Tips
The battery pack should be fully charged before you use the PDA for the first time. Within the acceptable
temperature range, it will take approximately 4 hours to fully charge from deplete state using the supplied
charging cradle.
Acceptable Charging Temperature Range
Charging Temperature Range
-20C (-4F) ~ 60C (140F)
Use correct battery and charger for your device - Use of incorrect battery or charger may degrade battery
performance and reduce the battery lifespan.
Assign one charging cradle to each device - Sharing a charging cradle among users is a common
practice. However, sharing the charger may cause the user to pick up a battery that may have not been fully
charged. We recommend assigning a cradle to each device to make sure the battery is fully charged. Green
LED indicated the battery is fully charged.
Charge the battery when prompted - You will get an audible alert with a pop-up message when the battery
is low. Failure to charge the battery may consume all RTC power and system time will reset to default. When
main battery is detached, the RTC battery will keep the system time information for as long as 5 minutes.
Use 2 batteries supplied alternatively - You can increase the battery lifespan by using 2 batteries
alternatively. If you are carrying a spare battery, we recommend charging the spare battery up to about 80%
of its full capacity. More batteries may be used for more reliability.
Clean the battery contact surfaces regularly - Dirty contact points are a main source of charging problems.
Regular cleaning is required for optimal performance. When cleaning it, please use a soft cloth. Cleaning
with liquid material is not recommended. (Pure alcohol may be used.)
