With the Rice Lake 550 Digital Chair scale there are certain precautions that should be taken to prevent personal
injury to the user and damage to your scale.

2.1 Safety Signals

Safety Signal Definitions:

Indicates a potentially hazardous situation that, if not avoided, may result in death or serious injury

Indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury.

Indicates information about procedures that, if not observed, could result in damage to equipment.

2.2 Safety Precautions

Do not operate or work on this equipment unless you have read and understand instructions in the
manual. Failure to follow the instructions or heed the warnings could result in injury or death. Contact
any Rice Lake Weighing Systems dealer for replacement manuals. Proper care is your responsibility.

Before attempting to operate this unit, make sure every individual who operates or works with this unit
has read and understands the following safety information. Plea

se follow these instructions carefully.

• Do not transport the scale while the platform is loaded.

• Always lock the caster brakes of the chair before seating the patient.

• Make sure the footrest is in the up position when seating t

he patient.

• Do not drop the scale or subject it to violent shocks.

• For accurate weighing, the scale must be placed on a flat, stable surface.

• For accurate weighing, verify proper operation according to the procedure

described in this manual

before each use.

• Weight exceeding the maximum capacity (660 Lb/300

Kg) may damage your scale.

• Do not use in the presence of flammable materials.

• Operating at other voltages and frequencies

than specified could damage the equipment. Use only

medically approved AC adapters.

• If the “

LO Bat” indicator activates, for accurate weighing, replace the batteries or connect the scale to an

AC power source as soon as possible.

• These scales are used to determine weight

• To avoid cross contamination, the scale plate must be cleaned regularly

of people while sitting.

. It is recommended after each
weighing which could result in potential contamination such as when there is direct skin contact during
the weighing process.

• The scale is not waterproof so avoid cont

5.0 RS-232 Communication

USB Connection

RS-232 Connection

The scale comes with an RS-232 port which enables weight data to be transmitted to other equipment, such as a
computer or printer. The RS-232 cable with DB-9 connector (PN 100719) is available from Rice Lake Weighing
System. Figure 3-18 on page 9 shows where the RS-232 connection is.

The RS-232 parameters are 9600 baud (selec
and no handshaking.

There are three methods of communication:

• Pushbutton keypad print

• Standard remote protocol

• Escape protocol
