Battery maintenance
When operating the VIPER from battery power, pay par-
ticular attention to:
1. Low battery warning -When the battery reaches the end of
its charge, a “battery low” message appears, a beeping alarm
sounds, and a PowerTool window appears if CDE is run-
ning. These indications mean you have approximately 15
minutes to complete your work before the battery charge is
exhausted.
2. When this occurs, follow the proper procedure to shut down
the VIPER quickly and safely, or connect the AC adapter to
maintain system operation. The VIPER will continue to
remind you about the low battery status if you continue to
use battery power.
Refer to “Shutting VIPER down” on page 33 for more
information on shutting down the VIPER.
Battery charging
When the AC Adapter is plugged in, the system automati-
cally begins charging the battery. If an over 140º F
(60º C) temperature condition occurs while charging the
battery, the process will be stopped. If the battery tem-
perature falls below 122º F (50º C), the system will
resume the battery charging process.
