KEY PAD FUNCTIONS
* MODE / CAL
Mode selection: Press the key once to change weight unit.
G=Grams, OZ= Ounces, DWT= Pennyweight, OZT=Troy ounces
MX-300 Accuracy: +/- 0.1g, 0.005oz, 0.1dwt, 0.005ozt
The Cal Key is used to put the scale in Calibration mode as explained in the calibration instructions on the other
page.
* ON/OFF
Press and quickly release this key to turn unit on.
Press and hold to turn off scale
* TARE
Press tare to reset the scale to zero. Tare can be used for eliminating the weight value of an empty container. Place
an empty container on the scale and press TARE. Then place the items to be weighed in the container. Tare is also
used as MEMORY. Simply place items to be weighed on the tray, press TARE then remove the items. The weight
of the items will be displayed as a negative value and remain on the display in memory for easy reading.
NOTE: When all weight is removed from the weighing tray, the tared value of a container will be displayed as a
negative number. Depress tare again to return the to zero.
* Backlight
To turn on the backlight, simply turn the scale on then press the backlight key. The backlight will remain on for
approximately 15 seconds.
** These electronic scale are precision instruments. Do not attempt to weigh near an in-use cell phone, radio,
computer or other electronic device. These devices emit RF and can cause incorrect or unstable scale readings.
Only operate in an interference free, very stable environment. If your scale ever performs poorly, try moving the
scale to a different location.
Please take good care of your MX-300 / MX-300

PROPER OPERATION AND ENVIRONMENT
* If the display ever becomes locked on Out2, please recalibrate the scale as outlined below.
* Always use a gentle touch on the buttons - don't press hard!
* Avoid lengthy exposure to extreme heat or cold, your scaleworks best when operated at normal room
temperature. Always allow theunit to acclimate to a normal room temperature for at least one hourbefore use.
* Allow sufficient warm up time. Turn the scale On and wait 30seconds to give the internal components a chance
to stabilize beforeweighing.
* The cleaner the environment the better. Dust, dirt,moisture, vibration, air currents and proximity to other
electronicequipment can all cause an adverse effect on the reliability andaccuracy of your scale.
* Handle with care. Gently apply all items to be weighed ontotray top. Although this scale is designed to be quite
durable, try toavoid rough treatment as this may permanently damage the internalsensor and void your warranty.
* Avoid shaking, dropping or otherwise shocking the scale. This is a precision instrument and must be handled
with extreme care.
* Only operate the scale on a stable, vibration free surface.
* These electronic scales are precision instruments. Do notoperate near an in-use cell phone, cordless phone,
radio, computer orother electronic device. These devices emit RF and can cause unstablescale readings. If your
scale ever performs poorly, try moving thescale to a different room or location.
* This is a very precise scale - the display may seem to wanderor jump when weighing. This is due to air currents
or vibrations.Stable weighing is achieved when the display remains fixed for 3seconds.
