Z TROUBLESHOOTING & OPERATION NOTES:

Low Batteries & bad battery connections are the #1 cause of scale malfunction and inaccuracy! We

test all of our scale returns from consumers. Fully 60% of consumer returns are battery related
problems. This sounds silly but it's true! A scale will perform slowly, or read inaccurately when it has low
batteries. Please replace the batteries often (and only use good quality batteries). We include good
quality batteries with all of our scales but batteries can run low in storage. If your scale simply won't
turn on while on Battery power, this is often caused by loose battery connections. Battery prongs
(terminals) are made of metal. They must be making good contact with your batteries in order for the
scale to power on. You can use a paperclip to slightly bend the battery prongs to make them have a
better connection. Also some poorly designed batteries have recessed or partially obstructed battery
terminals. This may cause your prongs to be touching the plastic housing of the battery instead of the
metal battery terminal.

1) If the Display ever becomes locked showing "Out2", please recalibrate the scale as outlined in the
manual

2) If the Display ever becomes locked on LLLL or EEEE, this indicates that the scale was shocked, dropped
or otherwise damaged and the delicate weighing sensors have been damaged. You can try recalibrating
the scale (If the sensor has not been hurt too badly it will work again after recalibration). Otherwise you
will have to follow the warranty instructions that came with your scale.

3) If the display becomes locked on 8888, this often indicates low batteries. However sometimes it also
may indicate a serious zero mark error. This means when you turn the scale on, it can't determine what
zero is (a slight zero mark error will cause situation #1 above) Thus, if new batteries do not fix this error
the scale will have to be sent to us for replacement under our Lifetime/30 year warranty program.

4) If the display shows UNST, this means the scale is not stable. Please try operating the scale on a more
stable surface and be sure nothing is on the tray or stuck under the tray when you turn it on. If this
situation persists, it may be an indication of fatal load cell damage. Try calibrating the scale - if this does
not work please follow the warranty instructions.

Although the Z is designed to be extremely durable, It’s important that you never overload or
drop/shock the scale. Scales are delicate instruments and unlike Cellular phones, scales have delicate
sensors that determine how much an item weighs. If you drop or shock your scale, these sensors "feel"
the shock and are sometimes destroyed. This happens with all digital scales. We design our scales to be
as resistant to shock or drops as possible, however there is no way for us to protect 100% against load
cell or sensor damage. A well-treated scale will provide years of reliable and accurate weighing.
However an abused scale will only work until it’s sensors are damaged.

PLEASE READ COMPLETE INSTRUCTIONS BEFORE USE

Thank you for purchasing The Z. With normal care and proper treatment it will provide years of reliable
service. Please read all operating instructions carefully.

.KEEP THE FOLLOWING POINTS IN MIND:

* If the display becomes locked on Out2 please recalibrate the scale.

* Avoid lengthy exposure to extreme heat or cold, your scale works best when operated at normal room
temperature. Always allow the unit to acclimate to a normal room temperature for at least one hour
before use.

* Allow sufficient warm up time. Turn the scale On and wait several seconds to give the internal
components a chance to stabilize before weighing.

* The cleaner the environment the better. Dust, dirt, moisture, vibration, air currents and proximity to
other electronic equipment can all cause an adverse effect on the reliability and accuracy of your scale.

* Handle with care. Gently apply all items to be weighed onto tray top. Although this scale is designed to
be quite durable, try to avoid rough treatment as this may permanently damage the internal sensor and
void your warranty.

* Avoid shaking, dropping or otherwise shocking the scale. This is a precision instrument and MUST BE
HANDLED WITH EXTREME CARE.

*IMPORTANT ADVICE: Place the item to be weighed on the platform, after the stable weight is

displayed remove the item immediately. This will prolong the longevity and accuracy of this weighing
instrument..

.** These electronic scale are precision instruments. Do not operate near an in-use cell phone, cordless
phone, radio, computer or other electronic device. These devices emit RF and can cause unstable scale
readings. If your scale ever performs poorly, try moving the scale to a different room or location. This is
a very precise scale - the display may seem to wander or jump when weighing. This is due to air currents
or vibrations. Stable weighing is achieved when the display remains fixed for 3 seconds.

OPERATION_____________________________________________

Battery Replacement:

1) Three #357 button batteries are required.

2) To install batteries:

a) Turn the scale upside-down and open the battery compartment

b) Place batteries into battery compartment aligned correctly.
