Krown Manufacturing PVCO-C - Manual (Page 5)

The Pocket Speak and Read VCO® (PVCO) is powered by two AAA
alkaline bateries. Install new batteries before you first use the PVCO. When the
batteries begin to weaken, the PVCO will flash, “!!BATTERY LOW!!” four
times when the PVCO is first turned on. At this time, it is best to replace the
batteries immediately to ensure good working condition for the PVCO.
To install the battery please follow these easy steps.
1. Press ON/OFF button to turn off the unit.
2. Open the battery compartment cover by pushing in the direction of the
arrow shown in the figure below.
3. Remove old batteries, if necessary, and install new batteries as indicated
by the polarity symbols (“+” and “-”) in the battery compartment.
