All packing materials such as internal bags, plastic collars,
plastic films, and carton inserts are not part of this product
and should be discarded.
Do not try to disassemble the unit.
Only use a wall outlet to charge your Sero 7 LE and the
power adapter that came with the device.
Do not expose the unit to moisture or water.
Keep the unit clean by wiping it with a slightly damp cloth.
To prevent hearing damage, never use headphones at
excessive volume levels. Listening to loud sounds for an
extended period may cause temporary or permanent
hearing loss.
Never use Sero 7 LE while operating a motor vehicle or
bicycle.
If you feel discomfort in your hands or any pain using Sero
7 LE, please stop immediately.
In case of long periods of use, take frequent breaks.
If a small part is coming out of the Sero 7 LE, do not try to
remove it. Keep it away from small children.
31Appendix B
Never force a connector into a port of Sero 7 LE. If a
connector and a port do not join with reasonable force,
make sure that the connector matches the port and that
you have positioned the connector correctly in relation to
the port.
To clean the screen, simply use a soft damp cloth. Do not
use alcohol, solvent, aerosol spray or abrasive cleaners to
clean your Sero 7 LE.
The product and the adapter should be periodically
examined for conditions that may result in the risk of fire,
electric shock, or injury to persons and that, in an event
such conditions, the adapter should not be used until
properly repaired.
Operate Sero 7 LE in a place where the temperature
is between 0º and 35ºC (32º to 95ºF). Low or high
temperature conditions might temporarily shorten battery
life or cause Sero 7 LE to temporarily stop working properly.
Avoid dramatic changes in temperature or humidity when
using Sero 7 LE, as condensation may form on or within
Sero 7 LE.
Store Sero 7 LE in a place where the temperature is
between -20º and 45ºC (-4º to 113ºF). Don’t leave Sero 7 LE
in your car because temperatures in parked cars can exceed
this range.
When you’re using Sero 7 LE or charging the battery, it is
normal for Sero 7 LE to get warm. The exterior of Sero 7
LE functions as a cooling surface that transfers heat from
inside the unit to the cooler air outside.
The rechargeable battery in Sero 7 LE should be replaced
only by Hisense Service.
Do not expose a battery pack or installed batteries to
excessive heat such as sunshine, fire or the like.
If you will not use Sero 7 LE frequently, then we recommend
that you fully charge and discharge the battery every three
months in order to maximize the battery lifespan.
If you will not use Sero 7 LE frequently, then we recommend
that you keep the battery level at around 50 percent in
order to maximize the battery life span.
32Appendix B
If Sero 7 LE has not been used for a long period of time,
then the battery might be in an over-discharge protection
mode and take longer to charge.
Never remove or insert microSD card while the Sero 7 LE is
powered on.
The manufacturer is not responsible for any radio or TV
interference caused by unauthorized modifications to
this equipment. Such modifications could void the user’s
authority to operate the equipment.
Sero 7 LE North America edition is limited using channel
1-11. This limited operation can be only set by software
and was done before the product down from the product
line. All the products for North America marketing were
embedded this limited before shipping. Customers have no
way to choose the channel 12 & 13.
Certification and Compliance
Exposure to Radio Frequency Energy
Sero 7 LE contains radio transmitters and receivers. When
on, Sero 7 LE sends and receives radio frequency (RF) energy
through its antenna. The Wireless antenna is located on the
back of the device, see Understanding Your Sero 7 LE Tablet
on page 5 for more details. Sero 7 LE has been tested
and meets the SAR (Specific Absorption Rate) exposure
requirements for WLAN operation.
Sero 7 LE is designed and manufactured to comply with
the limits for exposure to RF energy set by the Federal
Communications Commission (FCC) of the United State. The
exposure standard employs a unit of measurement known as
the specific absorption rate, or SAR. The SAR limit applicable to
Sero 7 LE set by the FCC is 1.6 watts per kilogram (W/kg). Tests
for SAR are conducted using standard operating positions
specified by these agencies, with Sero 7 LE transmitting at its
highest certified power level in all tested frequency bands.
Although SAR is determined at the highest certified power
level in each frequency band, the actual SAR level of Sero 7
LE while in operation can be well below the maximum value
33Appendix B
because Sero 7 LE adjusts its WLAN transmitting power based
in part on orientation and proximity to the wireless network.
In general, the closer you are to a WLAN Router, the lower the
WLAN transmitting power level.
Sero 7 LE has been tested, and meets the FCC and European
Union RF exposure guidelines for WLAN operation. When
tested at direct body contact, Sero 7 LE’s maximum SAR value
for each frequency band is outlined below:

FCC Compliance Statement
This device complies with part 15 of the FCC rules. Operation
is subject to the following two conditions: (1) this device
may not cause harmful interference, and (2) this device must
accept any interference received, including interference that
may cause undesired operation.
Information to Users
According to the FCC Part 15.19, 15.21, and 15.105 rules, for this EUT, the instructions or operation manual
furnished the user shall include the following or similar statement, placed in a prominent location in the text of the
manual:
FCC RF Exposure Information and Statement
The SAR limit of USA (FCC) is 1.6 W/kg averaged over one gram of tissue. Device types Sero 7 LE/E2371 (FCC
ID: W9HPADP0005) has also been tested against this SAR limit. The highest SAR value reported under this
standard during product certification for use at the properly worn on the body is 0.6186W/kg. This device was
tested for typical body-worn operations with the back of the handset kept 0cm from the body. To maintain
compliance with FCC RF exposure requirements, use accessories that maintain a 0cm separation distance between
the user's body and the back of the handset. The use of belt clips, holsters and similar accessories should not
contain metallic components in its assembly. The use of accessories that do not satisfy these requirements may not
comply with FCC RF exposure requirements, and should be avoided.
FCC Warning
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
NOTE 1: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help.
NOTE 2: Any changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
