Additional Features

Battery Life Indications [ ] :
The battery life remaining in the scale is shown on the LCD as a battery shape with 3 segment bar graph.

Auto Tare and Overload Indicator Feature:

The unit will tare off any weight less than (240 lbs / 110 kg) while powering up. If the weight is more than its capacity, the unit will display “OL” to indicate overload. The “OL” will also display when the gross weight is more than its capacity.

For example: The unit starts with 230 pounds on its platform-display reads 0; placing 25 pounds makes the unit display OL.

Auto Shut Off Feature:

Auto Shut Off (APO) – The unit will automatically shut off after 10 minutes if the weight on its platform does not change by more than 1oz (40g) in that period of time. Pressing [TARE] key when the unit displays the message in Figure-2 toggles between APO ON and APO OFF.

If the display and control unit is out of range of the scale platform and it turns off because of the APO, the scale platform will remain ON and subsequent connection will not be possible unless the batteries in the platform are removed and re-installed after a 60 second delay.

Troubleshooting

The CC240RF has been designed with the rough conditions of service work in mind. However, it is a precision instrument and, as such, certain precautions need to be observed to enjoy the benefits of its performance for a long time.

1. Control and display unit does not turn on:
   a. Check for dead batteries.
   b. Check for reversed polarity.
   c. Remove 9 volt alkaline battery for one minute; replace battery, listening for the battery installed tones.
   The control and display unit will produce 2 beeps then 5 faster beeps.
2. Control and display unit fails to connect to scale platform:
   a. Make sure you are within 5 feet (1.5 m.) of the scale platform.
   b. Check for dead batteries in the scale platform.
   c. Check the polarity of the batteries in the scale platform.
   d. Use 4 fresh AA alkaline batteries.
3. Items 1 and 2 are satisfied but the control and display unit still fails to connect:
   
   a. Place the control and display unit close to but
   not on top of the scale platform then press
   POWER [ ] key on the control and display
   unit.
   b. When the display gets to rf29 / CH x (See Fig.
   4), press [TARE] the display will change to rf29/ OPEn (See Fig. 12).
   c. When the control and display unit connects to the scale platform and the display enters the weighing mode, press and hold the POWER [ ] key and then press the [LB / KG] key and release both.
   d. In addition to displaying the current channel, the display will compare 4 ID’s between the control and display unit and the scale platform.
   e. The display will show the word “Good” in each case. If the ID’s do not match then a new application ID needs to be programmed. Please, contact the factory for instructions on how to do this.

Application ID:

The control and display unit and the scale platform are paired together at the factory. This feature allows the scale platform to communicate only with it’s paired control and display unit. Occasionally, is may be required to link the scale platform with a different control and display unit. Please, contact the factory for assistance with this function.

Install Batteries:

When the control and display unit is turned on, it will display the voltage of its battery (See Fig. 3). CPS recommends replacing the battery in the control and display unit with a fresh 9 V alkaline battery when the reading is 7.00 VDC, although useful operation can be obtained with battery voltages all the way to 6.00 VDC. During operation, the amount of battery life remaining will be displayed in the battery symbol on the display. When the battery is correctly installed, you will hear 2 tones followed by 5 faster tones. After the control and display unit connects with the scale platform, the voltage of the battery pack in the platform will be shown on the display (See Fig. 7). CPS recommends changing the scale platform batteries when the reading is 4.5 volts, although useful battery operation will result all the way down to 4.2 VDC; always use a set of 4 AA alkaline cells. When batteries are correctly installed, the scale platform will product a 7 tone musical tune.

Note : For optimum performance, always replace both the HHLD and the Scale Platform batteries atthe same time. Ensure that you hear the appropriate tone, if not, remove, wait 1 minute and reinstall battery.

Note : It is recommended that the HHLD and the Scale Platform be turned off prior to removing any batteries. Removing a battery when the Scale Platform is connected to the Hand Held, may cause the system to hang-up.Remove batteries from both devices if you feel you must remove a battery during operation.

Low Battery Indication:

If the system detects a low battery condition, the system will turn itself off in a safe condition. The display will show the word “CELL” and either “rxxx” or “Lxxx”. The “r” indicates the voltage of the scale platform batteries and “L” the voltage of the control and display unit battery voltage (See Fig. 3 & 7). The display then changes to “CPS Abrt” after a brief delay and then the system shuts off.

External Interference:

In the unlikely event that the CC240RF has difficulty maintaining connectivity or has numerous instances of the display freezing, no response to key entries, etc. the most probable cause is interference from other ISM band devices in the same channel. In that case, press and hold the POWER [ ] key and press the [TARE] key. To check that the channel has changed, press and hold the POWER [ ] key and then press the [LB / KG] key. The display will show all [4 id / Good] settings and then will show the new channel number and return to the normal weigh mode.

This instrument contains one or more
RF devices with FCC ID: X8BMT240, IC: 8826-MT240.
This product conforms to the applicable parts of FCC Rule 15.
