Battery
The battery in the PGA3500 is intended to provide more than enough power to operate the unit continuously for an eight-hour shift. When Battery Low is displayed on the LCD screen, the unit is in need of a charge. To charge the PGA3500, plug it into a 110 or 220VAC power source using the supplied power cord. The LED above the power cord input will appear red while the unit is being charged, and it will turn to green when charging is complete.
For maximum battery life, do not recharge the battery after each use unless the Battery Low message appears on the screen. Reducing the number of times that the unit is charged will maintain the battery’s original storage capacity for a longer period of time.
It is possible to view the condition of the battery by accessing Menu page #9 - Battery Status.
