Laser Information
The Unitech HT680 series is certified in the U.S. to conform to the
requirements of DHHS/CDRH 21CFR Subchapter J and to the requirements of
IEC 825-1. Class II and Class 2 products are not considered to be hazardous.
The HT680 series contains internally a Visible Laser Diode (VLD) whose
emissions do not exceed the maximum limits as set forth in the above
regulations. The scanner is designed so that there is no human access to
harmful laser light during normal operation, user maintenance or during
prescribed service operations.
The laser safety warning label required by the DHHS/IEC for the HT680 series'
optional laser scanner module is located on the memory compartment cover,
on the back of the unit.
CAUTION! Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous laser light.
Use of optical instruments with the scanner will increase eye
hazard. Optical instruments include binoculars, microscopes, and
magnifying glasses. This does not include eyeglasses worn by the
user.
Battery Notices
The HT680 is equipped with a Lithium-Ion battery pack and backup battery.
Both batteries will discharge after an extended period of not being used.
When both batteries are discharged, recharge the unit for 16 hours in order to
fully charge the main battery and backup battery. Recharge the HT680 through
the following:
1. Plug the USB charging cable to the HT680 and plug the 5V/3A AC-DC
adapter to the power jack of the USB charging cable.
2. Place the HT680 into the docking station and plug the 5V/3A AC-DC
adapter to the power jack of the docking station.

v
If the main battery is removed, the backup battery ensures the data on SDRAM
is safe for up to 6 hours. To prevent data loss, do not leave the HT680
uncharged with the main battery removed for an extended period. See First
Time to Charge the Main Battery & Backup Battery on page 9 for more details.
Note: Rechargeable batteries are advised to replace every year or when 500
charge/discharge cycles achieved to guarantee optimal performance. It
is normal that the battery balloons or expands beyond one year or the
maximum of 500 cycles. Although it does not cause harm, it cannot be
used again and must be disposed of according to the location's safe
battery disposal procedures.
If the performance decrease is greater than 20% in a Lithium-Ion battery,
the battery is at the end of its life cycle. Do not continue to use, and
ensure the battery is disposed of properly.
The length of time that a battery power lasts depends on the battery type and
how the device is used. Conserve the battery life through the following:
 Avoid frequent full discharges because this places additional strain on the
battery. Several partial discharges with frequent recharges are better than
a deep one. Recharging a partially charged lithium-Ion battery does not
cause harm because there is no memory.
 Keep the lithium-Ion battery cool. Avoid a hot car. For prolonged storage,
keep the battery at a 40% charge level.
 Do not leave the lithium-Ion battery discharged and unused for an
extended period because the battery will wear out and the longevity of the
battery will be at least shorter than half of the one with frequent recharges.
Battery charge notice
It is important to consider the environment temperature whenever the
Lithium-Ion battery pack is charged. Charging is most efficient at normal room
temperature or in a slightly cooler environment. It is essential that batteries are
charged within the stated range of 10°C to 45°C. Charging batteries outside of
the specified range could damage the batteries and shorten their charging life
cycle.
CAUTION! Do not charge batteries at a temperature lower than 0°C, which will
increase the internal resistance to cause heat and make the
batteries unstable and unsafe. Please use a battery temperature
detecting device for a charger to ensure a safe charging
temperature range. Further, to protect and avoid battery from

vi
inflating, the battery is detected for thermal protection and will not
be charged when the temperature of battery is over 50 degrees.
Do not leave the terminal for a long time in the charging cradle and
do not charge the battery with a cable long, which will shorten the
battery life and cause battery expanding/ballooning. The unit
should not be subject to very high temperature, excessive moisture,
and direct heat. Avoid the battery from being fully charged and
staying in a high temperature environment. Avoid terminal or spare
battery from staying in a hot vehicle. For prolonging the storage
time, keep the battery at a 40% charge level. Lithium ion batteries
oxidize least when they are stored at the state of 40% charge.
Storage and safety notice
Although charged Lithium-Ion batteries may be left unused for several months,
their capacity may be depleted due to build up of internal resistance. If this
happens they will require recharging prior to use. Lithium-Ion batteries may be
stored at temperatures between -20°C to 60°C, however they may deplete
more rapidly at the higher temperature ranges. It is recommended to store
batteries within normal room temperature ranges.
Warranty
The following items covered under Unitech Limited Warranty are free from
defects during normal use:
 HT680 – 1-year limited warranty.
 Accessories – limited warranty depending upon your local dealer’s
definition
Warranty becomes void if equipment is modified, improperly installed or used,
dam-aged by accident or neglect, or if any parts are improperly installed or
replaced by the user.
Use only the adapter supplied. Using the wrong adapter may damage the unit
and will void the warranty.
