4. Getting Started
In order to obtain an accurate weighing result, the weighing platform must be
placed on a strong and level surface. Avoid using the platform and this
instrument in environment where excessive wind flow, vibration and extreme
temperature change exist
General Warnings: -
•The instrument is not an explosion proof device.
•The instrument is not a water proof device.
•Do not open the instrument, no user serviceable parts inside. Always
contact your dealer for service.
•The instrument not to be subject to shock, excessive vibration or
extremes of temperature (before or after installation).
4.1 Built-In Rechargeable Battery
The instrument is equipped with a built-in rechargeable battery. Before first
time use, recharge it for at least 8 hours to ensure the best battery
performance.
4.2 Power Adaptor
Before plugging in the power adaptor, check and make sure the input voltage
of the adaptor matches with output voltage of the electricity outlet. If not,
contact your dealer immediately.
Note: - for FM18S
The DC input connector and the output plugs of the power adaptor both comes
with a cover. Always screw tightly the cover to the DC input connector when
not used and battery recharge is in process.

Notes: -
1. Default setting of wireless data communication = send only. Position of
jumper J1 on main board needs to be changed in order to trigger
wireless data communication receive function (if it is the case, receive
function of the RS232 comport will then be disabled). Contact your
dealer for more information.
2. This instrument supports bi-directional data for either the RS232
comport or the TTL comport. Default setting of: -
•RS232 = bi-directional,
•TTL comport = single direction (transmission only).
If bi-directional TTL data communication is required, adjust jumper setting on
board. On board jumper setting may be required, refer to Appendix A
Bi-Directional Communication Jumper Setting for detailed information.
