Checking Battery Voltage Level - Kurzweil PC88 Musician's Manual

Introducing the PC88

Checking Battery Voltage Level

Checking Battery Voltage Level
Your PC88 stores Setups youÕve created, as well as information about your effects and group
preferences, in internal memory. This memory is backed by a lithium battery that will last 3-5
years. Although a start-up message alerts you to a low battery level, you may want to check
the battery voltage from time to time. As a safeguard, you may want to back up your Setups to
an external device with the Dump all Setups option on the Global menu.
Internal Voices and ROM Setups are not dependent on battery-backed memory.
To check the battery level:
1.
2.
3.
1-8
Press the 4, 5, and 6 buttons simultaneously. The top line of the PC88Õs display will look
something like this:
SCAN|2.4|W=123|B=2.9
Check the part of the display labelled ÒB=x.xÓ. This is the battery voltage level. It should
normally be 2.8 or higher. When this value declines to 2.4 or below, you should have your
Kurzweil dealer replace the battery. Note that when the battery voltage level is 2.4 there is
less than two months of battery life remaining; when the battery voltage level is 2.0 or
below, memory failure is likely.
Press Cancel and Enter simultaneously to return to normal PC88 operation.
