KEYS FUNCTION
In weighing status hold the key for more than 5s, it enters setup mode
(All the setting in this mode should be recorded with the calibration
header on; or the data will lose).
Tare function in weighing status.
Zero function in weighing status.
For selecting.
Weighing accumulation
Long press for 1sec to turn on. Long Press for 3sec to turn off.

OPERATION
Turning on
Turn on the power, the indicator performs self-checking and go into weighing mode.
Zero function
Press for zero return, indicator returns to zero within the zero range 2%FS.
Please make sure the stabilization light is on when zero operation.
If obstruction occurs by more than 1 wireless indicator working at same time,
you can open both indicator and scale, change the number of transcoder
inside with same number and restart.
Tare
At weighing mode, press to deduct displaying weight while it is positive
and stabilization light is on. At no-load status of the scale, press to
deduct tare and then tare light is off.
Manual accumulation
At weighing mode, press , it displays “ADD-01”, “01” means times of
accumulation (the Max times is 99 and then it will return to 01). After then
it will display the value of accumulation for 3s and then back to normal
weighing mode by itself.

6
Check accumulation
At weighing mode, press , it will display the times and the value of current
accumulation, after then back to normal weighing mode automatically.
Clear accumulation
At weighing mode, press , it displays “ADD---” and back to weighing
mode which means clear the current accumulation.
PARAMETERS SETUP
In weighing status, hold for more than 5s and entering setup mode. (P
mode, all the setting in this mode should be recorded with the calibration
header on; or the data will lose.)

RECHARGEABLE LITHIUM BATTERY
Battery inside of scale is Lithium battery. Please charge it after running
down for 7 hours the first three times. Please charge the battery for timing
if not use it often.
The battery is an easily exhausted product. And it is not granted free
guarantee.
MAINTENANCE
1. To guarantee indicator clarity and using life, the indicator shouldn’t be
placed directly under sunshine and should be set in the plain space.
2. The indicator can’t be placed into the place where the dust pollution and
vibration are serious.
3. Load cell should connect with indicator reliably, and the system should
be well connected into ground. The indicator must be protected from
high electrical field and high magnetic field.
In order to protect the operator, indicator and relevant device, you should
mount lightning rod in thunderstorm frequently happening area.
• Load cell and indicator are static sensitive device, you must adopt
anti-static measures.
4. It is strictly forbidden to clean the case of indicator with intensive solvents
(for example: benzene and nitro oils).

11
5. Liquid and conducting particle should not be poured into the indicator,
otherwise the electronic components will be damaged and electric shock
is likely to happen.
6. You should cut off power supply of indicator and relevant device before
you pull –in and out the connecting line of indicator and external device.
• You must cut off power supply of indicator, before pulling out
connecting line of load cell.
7. During operation, if trouble occurs, operator must pull off the power
supply plug immediately, and user should return this indicator to our
company for repair.
Non-weighing manufacturer should not repair it, or by your-self,
otherwise further destruction may happen.
8. The storage is not granted the free repair guarantee, because it is easily
exhausted products.
• In order to prolong using life, please charge the cell fully before using
it. If you don’t use the indicator for a long time, you must charge the
cell every two month and for eight hours/each charging time.
• Moving or installation must be carefully taken and must avoid strong
vibration, impact and bump in order to protect the storage cell from
being damaged.
9. From invoice date, the indicator has a one-year free repair period. If any
non-artificially obstacle about the indicator happens under correct using
conditions within this period. The user is allowed to send the product
with its guarantee card (of the correct number).
Back to our corporation for free repair. The indicator shouldn’t be taken
apart, otherwise free guarantee will be cancelled.
