FCC Notice
HDS800 Receiver complies with the limits for a
Class B digital device, pursuant to the Part 15 of the
FCC rules when it is used in Portable Mode. See Note
below related to Class B device.
Class B digital devices NOTE: 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 rea-
sonable 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 in-
structions, 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 deter-
mined by turning the equipment off and on, the user
is encouraged to try and correct the interference by
one or more of the following measures:
– Reorient or locate the receiving antenna.
– Increase the separation between the equipment
and receiver.
– Connect the equipment into an outlet on a cir-
cuit different from that to which the receiver is
connected.
– Consult the dealer or an experienced radio/TV
technician for help.
When HDS800 is used with an external power supply
or connected to an external device using the USB
port, it complies with the limits for a Class A digital
device, pursuant to the Part 15 of the FCC rules. See
Note below related to Class A device.
Class A digital devices NOTE: This equipment has
been tested and found to comply with the limits for
a Class A digital device, pursuant to Part 15 of the
FCC Rules. These limits are designed to provide rea-
sonable protection against harmful interference
when the equipment is operated in a commercial en-
vironment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual,
may cause harmful interference to radio communica-
tions. Operation of this equipment in a residential
area is likely to cause harmful interference in which
case the user will be required to correct the interfer-
ence at his own expense.
Remark: Any changes or modifications not expressly
approved by Ashtech, could void the right for user to
operate the equipment.
RF Safety Exposure To Radio Frequency Energy
(SAR)
Radio transmitting devices radiate Radio Frequency
(RF) energy during its operation. RF energy can be
absorbed into the human body and potentially can
cause adverse health effects if excessive levels are
absorbed. The unit of measurement for human expo-
sure to RF energy is "Specific Absorption Rate"
(SAR).
The Federal Communications Commission (FCC), In-
dustrie Canada (IC), and other agencies around the
world have established limits that incorporate a sub-
stantial safety margin designed to assure the safety
of all persons using this equipment. In order to certi-
fy this unit for sale in the US, Canada and Europe
this unit has been tested for RF exposure compliance
at a qualified test laboratory and found to comply
with the regulations regarding exposure to RF Energy.
SAR was measured with the unit (GSM Module)
transmitting at its maximum certified RF power. Of-
ten, however, during normal operation the unit (GSM
Module) will transmit much less than maximum pow-
er. Transmit power is controlled automatically and, in
general is reduced as you get closer to a cellular base
station. This reduction in transmit power will result
in a lower RF energy exposure and resulting SAR val-
ue.
FCC and CE UHF Safety Statement
The different versions of the UHF Transmitters are
FCC and CE compliant.
In order to comply with FCC and CE RF exposure
safety guidelines as body-worn, normal use of unit,
the following must be followed:
A distance of AT LEAST 10 feet (3 m) of separation
between the users body and the unit (UHF Transmit-
ter). This distance has been defined taken into ac-
count the FCC and CE Requirements and the worst
output power configuration.
Do NOT use the device in a manner such that it is in
direct contact with the body (e.g. on the lap). Such
use will likely exceed FCC RF safety exposure limits.
See www.fcc.gov/oet/rfsafety/ for more information
on RF exposure safety.
To comply with CE and FCC electrical safety regula-
tions, HDS800 should only be powered from a 9 to
28 V DC external source, with 20 W power limitation,
or the recommended battery (P/N 111374). The bat-
tery should be charged only with the supplied battery
charger (P/N 802064).
CAUTION
RISK OF EXPLOSION IF BATTERY REPLACED
BY AN INCORRECT TYPE.
DISPOSE OF USED BATTERIES
ACCORDING TO THE INSTRUCTIONS.
