Battery Management

The handheld is powered by a rechargeable lithium-ion battery that must be periodically charged.

Battery charging guidelines

Batteries may be charged overnight or for extended periods.

Batteries do not have to be discharged before recharging them.

Batteries may be plugged in for any amount of time to partially recharge the battery.

Always keep one of the two batteries fully charged in the battery charger. At the end of each workday, you may want to replace the battery with a fully charged battery and charge the other battery.

The upper right hand corner of each task screen includes a graphical battery charge indicator (battery gauge).

25% charge remaining

The battery gauge shows how much of a charge remains in the battery that is currently being used. (See Figure 10.)

If the battery gauge shows less than 50% charge remaining, you may want to replace the battery with a fully charged battery and place the other battery in the charger.

Low battery warning messages

The handheld warns you when battery power is low. You should replace the battery if a “battery low” message appears.

Handheld software protects you from totally losing power by requiring that the battery be changed or recharged when the charge drops to a very low level.

Sleep Mode

Once the battery is charged and installed, the handheld is ready to use at all times.

To conserve battery charge, the handheld will enter “sleep mode” after approximately two (2) minutes of no activity. During sleep mode, the screen will go blank.

To bring the handheld out of sleep mode, press the trigger.

The display will revert to the last function that was used.
