A member of the growing 9100 system's instrument fam-

ily, the 9I20A printer gives the 9100 series calculator

printing power. The 91204 will print, singularly or in any

combination, the contents of the calculator's X keyboard,

Y accumulate, and Z temporary registers. The printer will

also print the contents of the calculator's memory.

The Model 91204 requires either 115 or 230 volts AC

-+lOo/o, 50 to 60 Hertz and approxímately 45 watts of

power. With the printer disconnected from the AC power

source, slide the line voltage switch on the rear panel until

the line is under the voltage to be used.

Radio Frequency lnterference (RFl) is generated by many

electrical devices, included in this group is the 9120A. A

paper length of less than one foot will minimize the

amount of RFI generated by the printer; as the paper is

conductive it acts as an antenna.

To protect operating personnel, the National Electrical

Manufacturer's Association (NEMA) recommends that the

printer keyboard and cabinet be grounded. The printer is

equipped with a three-conductor power cable which, when

plugged into an appropriate receptacle, grounds the

cabinet of the printer. The center pin on the power cable

three-pronged connector is the ground connection.
