is on. Other factors that affect the operation time will include

batteries, such as the "Duracell
than conventional alkaline cells under high demand applica-
tions). Operation at lower temperatures will also reduce battery
life.
The SR-60 display can also show random symbols when the bat-
tery power is too low to drive the internal logic circuits correctly.
This is remedied by simply putting fresh batteries into the unit.
To preserve battery life, the SR-60 will automatically shut down
after 1 hour of no key presses. Simply power the unit on to
resume use.
