OPERATIONS DESCRIPTION.
HOW TO WEIGHT A PRODUCT
At the end of this countdown sequence, zeroes will appear in the view finder, indicating that
the scale is ready to use.
If not, see section reference to zero. Then place the product to be weighed on the plate and
you will see the weight in the corresponding indicator.
HOW TO ENTER PRICES
The product price per pound or kilogram is entered pressing the numbers of the keyboard to
indicate the desired value. This value will appear in the "PRICE" indicator and the total amount
to pay will be calculated automatically being shown in the "TOTAL" indicator. For example, if the
product price per pound in the previous examples is $8.20, just press
0
and the
following display will appear:
HOW TO CLEAR WRONG PRICES
When a mistaken price is entered, you can clear it in two ways:
a) Manually: Simply press the clear key and enter the correct price.
b) Automatically: The price is automatically cleared removing the product from the plate, except
if it's not enabled the fixed price function.
FIXED PRICE FUNCTION
When it is necessary to constantly be weighing the same kind of product, one does not change
its price, you can use the "FIXED PRICE" function. It is used to keep the price "FIXED" in the
"PRICE" indicator avoiding it to be automatically cleared when the weight is removed from the
scale.
To fix a price, follow these steps:
1.- Place the product on the plate.
2.- Enter the product price per pound or kilogram.
3.- Press
P-PACK
.
After these steps, a small arrow will light up in the upper right corner of the "TOTAL" indicator,
pointing to the label "P-PACK" (fixed price). As an example, suppose that the product is ham,
the weight is 4 pounds, and the price is $2.70 per pound after entering the fixed price, the view
finder will look like this:
To clear the fixed price function, just press the key.
USE OF THE "TARE"
When you wish to weight a product in a container but you do not want to consider the
containers weight during the operation, you can use the TARE function. To use this function
follow this steps:

1.- Place the empty container on the scale.
2.- Press the key. After some seconds the view finder will display:
3.- Remove the container and put the sugar inside it. When you remove the container, a
negative number (weight of the container) appears in the UPPER-LEFT indicator.
4.- Place the container on the scale and put in the container sugar until you have 15 lb. Then
enter the price per pound press .
It is important to mention that this function is substractive from the scale maximum capacity.
For example if you have a container that weights 7 lb, The scale will only be able to weight up to
33 lb of product to complete the maximum capacity.
HOW TO USE THE REFERENCE TO ZERO
This function has two uses:
a) Permanent tare: when you wish to weigh some products over a same container several
times, you should use this function , and to eliminate it, just remove the container from the
plate and press key again. As in the tare function this function is also substractive from
the scale capacity, for example: if you reference to 10 lb, the scale will only be able to weight
up to 30 lb.
Due to voltage variance or some other factor, it is posibble that without having any weight over
the plate, the view finder shows some weight, or that the zero flag it's not on, then press the key
and the scale will be referenced to zero turning the zero flag on.
HOW TO LOAD A MEMORY:
1) Press the key
RCL
and then the memory address (00-99) you wish to load or just press any of
the direct access keys , ..., .
Example:
If you wish to save $26.60 in the memory address 6, follow these steps:
1) Type .
2) Press
STO
.
3) Type or just press the direct access key .
With this sequence the price is saved in the memory address 06. If you wish to load the
memory of this example just type
RCL
or just , and in the "PRICE" indicator will be
displayed the price stored in memory, in this case will be $26.60
To change the price stored in a memory just type the new price and store it in the memory
address you want to change following the procedure described above. These keys are very
useful to avoid type the same price constantly. To use these memories we suggest to have at
hand the product list that are saved in each memory address
.
To delete all the memories that are stored, turn the scale on and during the countdown type
RCL
M+
½
and all the memories will be deleted to zero.
HOW TO TURN ON THE BACKLIGHT
This scale model has a backlight that helps you to see better the display information. It can be
turned on in two ways:
1) Automatically: when an AC adaptor is connected to the scale.
2) Manually: It can be performed by pressing the key.
And can be turned off in two ways:
1) Automatically: when the scale is powered only by battery and the battery is low the backlight
is turned off.
2) Manually: It can be performed by pressing the key.
Note: Using the backlight and only powering the scale with the battery, the charge of the battery
will last less hours
POWER OFF TIMER FUNCTION
This function is permanently enabled when the scale is on, and only when you do not have the
AC/DC power supply connected to the scale. When the scale is not use for a period of time
greater then 15 minutes, it will automaticaly turn off and therefore all the information of the
transaction you were doing will be lost. To turn on the scale again, just press the key, and
repeat your customers operations. The power off timer function permits you to save electricity
and avoids constant battery recharges.
USE OF THE BATTERY
As mentioned before, the scale can operate with a 6 volt built in battery or with an AC/DC
power supply. The battery is rechargeable using the AC/DC power supply.
BATTERY RECHARGE
To make this operation, just connect the AC/DC power supply to the scale for 10 HOURS
making sure that the scale was turned off. When you recharge the battery for some hours, but
the battery can not get enough charge to turn on the scale, then you must have to charge the
battery, in this case contact to your authorized distributor.

CHARGE AND DISCHARGE CYCLES
SERVICE LIFE IN RELATION TO CHARGE/DISCHARGE CYCLES
The charging capacity of the rechargeable battery in this scale decreases according to the
number of charge/discharge cycles, this causes that the service life is reduced to 1000 cycles.
For these reason the warranty period for the battery is limited to six months after the purchase
date of the scale.
LOW BATTERY INDICATOR
If the battery does not have enough energy to keep the scale operating a long time, a low
battery message will appear flicking in the "PRICE" indicator "LO bAt". This is the first warning
signal indicating that it is necessary to recharge the battery. Even with this signal, it is possible
for the scale to keep on operating for a short period of time (30 minutes), but after a second
warning signal appears "LO bAt" fix in the display, the scale stops itself and does not respond to
the instructions until the battery be recharged or be connected to the AC main.
HOW TO ACCESS THE COUNTERS
The scale is equipped with two important counters:The Calibration counter and the counter of
times that configuration has been changed.This counters must be only accesed by oficial
office of weights and measures inspectors.
The calibration counter displays the number of times the scale has been “recalibrated” by a
technician.
The counter of times that the internal configuration has been changed displays the number of
times that a technician has reconfigured the “internal function” in the scale.
In both cases, the customer can only check the amount that is displayed, but can not make any
changes.
To check the counter follow these instructions:
A) Calibration counter
1.- Turn on the scale
2. Press
STO
during the initial countdown, at the end of the
countdown the view finder will display:
B) Counter of times that the internal configuration has been changed
1.- Turn on the scale
2. Press
STO
during the initial countdown, at the end of the
countdown the view
finder will display:
If any of the two cases, to get to the normal operation mode, just turn off the scale and turn it on
again. Your scale leaves the factory like the examples.
OTHER IMPORTANT MESSAGES THAT APPEAR ON THE SCALE
This message indicates that a weight that exceeds the maximum capacity has been placed on
the scale. To correct it simply, remove the over weight.
This message appears in two different situations:
a) When the scale is turned on with an excessive weight on the plate (near to the half capacity
of the scale). To correct this situation remove the weight on the scale, turn off the scale, and
then turn it on again.
b) When the scale was handled roughly and/or got hitted during the shipment, wich caused
irreversible damages in its operation. In this case call your authorized distributor.
This message indicates a negative weight, this could happen if you lift or remove the scales
plate to correct this put the plate back in its place and press the key or turn the scale off
and then turn it on again.
This message appears when:
If we turn on the scale with a product on the plate, to eliminate this message simply remove
the product that is on the scale, turn off the scale and then turn it on again.
This message indicates that the total was exceeded when the multiplication price per weight
exceed 999999 then appear lines in the "TOTAL" indicator.
If this message appears in intervals on the display, indicates that the scale needs to be
recharged. Even with this advise the scale can continue working during a time of 30 min. If it
appears and after some seconds the scale turns off , it indicates that the scale is completely
discharged. In this point the scale doesn't work and all of the operations performed at that time
will be lost. To correct this problem connect the AC/DC adaptor for a period of time of 10 hrs.
and keeping the scale off. In case of using the scale during this period, there's no problem to use
it, only the recharge time will be higher.
This arrow indicates that the scale is working under the "FIXED PRICE" mode.
This arrow indicates that the scale AC adaptor is connected to the 120 VCA
