Turn the scale on or off by pressing ON/OFF. Automatic Sleep Function: The PC-400 has a feature called “Auto Shut-down” that turns the scale off after a preset time of no activity. This helps conserve battery life. The preset time is selectable from 1 minute to 60 minutes or it can be disabled so the scale remains on continuously.
RS-232 Connections: The PC-400 has a standard RS-232 output. To use this feature, the optional RS- 232 cable is needed. Plug one end of the RS-232 connector into the RJ-12 connector located on the rear of the scale. Attach the other end to your computer or printer.
4) Place full capacity (2lbs for the 2.2lb scale and 12lbs for the 13.2lb scale) on the platter and press ZERO. Wait for the scale to count down from “7” to “0. If the scale detects motion, the count will restart. When finished, the scale will return to the weigh mode.
When the scale is fully charged, all four dots will remain on. It takes approximately four hours to completely recharge the battery. The PC-400 can be used while it is being recharged. 3. The scale is ready to use, powered by the fully recharged battery.
To exit the setup mode, press and release the UNITS button until the scale returns to the weight mode. NOTE: No setup information is saved until the PC-400 exits the setup mode. A power failure while in the Setup Mode will cause changes to be lost.

Section 7. Data Communications Introduction to data communications: In the PC-400, data is sent to a printer or computer by using “asynchronous serial data communications.” Data is broken up and sent one piece at a time to the printer or computer. In spite of this apparent simplicity, a basic understanding of serial data communications is needed when setting up the PC- 400.
The number of bits sent by the PC-400 is controlled by the data bits, parity and stop bit configuration. The PC-400 is factory set for eight bits, no parity and one stop bit. This means that the eight bits following the start bit will be data, followed by a stop bit.
Data Output Format: In order for the serial data sent from the PC-400 to be useful, the data must be organized so that it is easy to read. To accomplish this, the PC-400 arranges the displayed data with additional text to indicate the active units and to indicate the presence of motion during the reading.
