Nota: Cuando se sustituyan las pilas, la calculadora tal vez no funcione correctamente. En este caso, quite las pilas,

espere un mínimo de dos minutos y luego

vuelva a instalarlas.

Además, si la calculadora recibe un golpe fuerte o está sometida a ruidos altos durante una operación de cálculo, es posible que ésta no pueda imprimir correctamente o que se pierda el resultado del cálculo. En este caso, el cálculo tendrá que hacerse otra vez.

MANERA DE CONECTAR EL ADAPTADOR DE CA (OPCIONAL)

Esta calculadora puede también funcionar con corriente alterna usando un adaptador de CA. Cuando el adaptador de CA está conectado a la calculadora, la fuente de alimentación se conmuta automáticamente de pilas secas a corriente alterna.
