The electronic function of the battery powered SP-70 is exactly the same
as its AC-powered cousin with only one notable exception – the addition
of a battery charge “gas gauge” indicator. This indicator is displayed as
the left-most character on the upper half of the LCD. The graphics below
depict the appearance of the indicator at various charge levels.
If the battery pack discharges to an extremely low level, the control will
issue an audio-visual warning. The beeper will “chirp” a rapid succession
of tones, a lower case letter “e” (for “empty”) will be displayed on the gas
gauge indicator, and the message “BATTERY VERY LOW” will appear on
the bottom half of the LCD readout.
If you receive this warning, it means that the control will likely lose power
within 10 minutes and one of the following three courses of action should
be immediately taken:
1. Attach the battery charger to the controller and plug it into an AC wall
power outlet. The control will then continue to run normally, but the
battery won’t begin charging properly until the control’s power switch
is turned off.
2. Set up and begin using a backup controller after turning off the dis-
charged control.
3. Turn off the control and replace the discharged battery pack with one
that is fully charged.
