OPERATIONS DESCRIPTION.
HOW TO WEIGHT A PRODUCT
At the end of scale initialization, 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.
9.-

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
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 .
After these steps, a small arrow will light up in the upper rig ht 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:

10
Suppose you are going to weight 15 pounds of sugar in a plastic container that weights 3.5 pounds and that the price per lb
is $1.80.
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.
b) 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.

11
PRICE ADD-UP
When you want to add some prices up follow these steps:
PRICE MULTIPLING FUNCTION
When you want to use the price per 1/4 or 1/2 lb or kg put the weight over the plate and enter price per 1/4 or 1/2 . Then
press or key automaticalOly appears the price per lb or kilogram. If the price does not exceed 999.99 It will be
displayed on the unit price. If you want to use any of these keys again remove the commodity and follow the same procedure.
HOW TO SAVE MEMORIES
Your scale has 100 memories to store the prices of 100 products that are sold more frequently. The memories are
numbered from 00 to 99.
To save a price in a memory location:
1) Type the price you wish to save.
2) Press key.
3)Type the memory address (00-99) in wich you wish to save the price, or you also can press any of the direct
access keys , ..., .
NOTE: We suggest to use an adhesive label to mark the direct access keys.
1.- Put the commodity over the plate with the
unit price (for example a price of $2.20 and a
weight of 1.50 lb) and press
M+
.
3.- Put another good with the unit price and then
press
M+
.
5.- To delete the sum total press key
when the sum total is displayed.
2.- Remove the commodity.
4.- When you press
M+
with the total
indicator in zeroes you will see the sum
total accumulator without adding any price
up.

12
HOW TO LOAD A MEMORY:
1) Press the key 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 .
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
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 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.

13
USE OF THE BATTERY
As mentioned before, the scale can operate with a 4 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 C
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 scales to keep on operating for a short period of time (30 minutes), but after a
second warning signal appears “LO bAt” fix in the sisplay, 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.

14
To check the counter follow these instructions:
Calibration counter
1.- Turn on the scale
2. Press 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 during the initial countdown, at the end of the countdown the view
finder will display
If any of the two cases, to get the normal operation mode, just turn off the scale and turn on. 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 pr oblem 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
