Canon introduces another palm printing calculator - the P1-DHV - featuring a stylish, silver metallic design and advanced calculations right in the palm of your hand. Time Calculation enables you to calculate time-based fee structures, while profit margin calculation can be calculated with the touch of a few keys. Tax rates can be stored and recalled whenever needed. And finally, the P1-DHV has a built-in battery indicator to let you know when it's time to change the batteries. Once again, the P1-DHV proves that success cannot be measured by size alone.
