This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

WARNING - FCC Regulations state that any unauthorized changes or modifications to this equipment not expressly approved by the manufacturer could void the user’s authority to operate this equipment.

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

- Reorient or relocate the receiving antenna.

- Increase the separation between the equipment and receiver.

- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.

Caution! The socket outlet shall be installed near the equipment and shall be easily accessible.

Aviso! El tomacorriente debe estar instalado cerca del equipo y debe quedar bien accesible.

In case of abnormal conditions

When this unit is exposed to strong RF noise and/or extreme physical shock during operation, or when the power cord is plugged into the AC outlet, the unit may start functioning abnormally which, in some rare occasions, all keys cease to respond. If such abnormal conditions are observed, unplug the AC cord from the socket. Keep the unit unplugged for about 5 seconds, reconnect the AC plug, then turn on the power.

En caso de condiciones anormales

Si expone esta unidad a ruido de RF intenso y/o a golpes fuertes durante la operación, o cuando enchufe el cable de alimentación en un tomacorriente de CA, la unidad puede comenzar a funcionar de forma anormal, por lo que, en algunos casos raros, todas las teclas pueden no ofrecer respuesta. Si experimenta estas condiciones anormales, desenchufe el cable de alimentación de CA del tomacorriente. Deje la unidad desenchufada durante unos 5 segundos, vuelva a enchufar el cable de alimentación de CA, y después conecte la alimentación.

ERRORS

There are several situations which will cause an overflow or an error condition. When this occurs, the error symbol “E” will be displayed and all keys will electronically lock. The contents of the memory at the time of the error are retained. If an “0.E” is printed on the tape at the time of the error, the clear the calculator. If an “E” with any numerals except zero is printed on the tape or if an “E” is the calculation can still be continued.

Error conditions:

1. Entry of more than 12 digits or 11 decimals.

2. When the integer portion of an answer exceeds 12 digits.

3. When the integer portion of the contents of the memory or grand total memory

4. When any number is divided by zero. (Ex. 5 0 )

DECIMAL SYSTEM

Input override decimal feature

The calculator operates on a principle of floating decimal entries with preset decimal answers.

1. An

entry may contain up to 11 decimal places, regardless of the decimal selector

setting.

Answers will be printed to the preset decimal position except when an underflow condition prevails.

Output override decimal feature

This feature enables an answer to be printed in the floating decimal when the result is too small to be picked up within the range of the preset decimal.
