DESCRIPTION
The RPC-30 has a built in battery backed
Calendar/ clock. When used in conjunction with the
DAT E$ and TIM E$ comm ands, the curr ent date and
time can be set and read.
The life of the battery depends upon the power
consumption of RAM in U10. Generally, you can
expect a battery life of 5 to 10 year s.
The cloc k chip, U17, contains a built in cr ystal.
Accuracy is about 1 minute/month and is not adjustable.
Refer to the CAM BASIC Pr ogramm ing Manual for
