3. Start modemsetup software
There are two dialogs in the modemsetup software. The first dialog is SETUP (diagram 2 and
diagram 3). This dialog used to setup COM parameter. After finished set COM parameter, push the
Connect[C] button to connect the PIP900 modem. The second dialog is Te st Transmi t (diagram 3).
This dialog used to select Transmit Power, Modulate Data kinds and Transmit Duty. If you want to
output Max Power, please select Power level 4(MAX). Operation Step:
a. Connect PC and PIP900 use special cable.
b. In SETUP dialog select the COM (COM1 or COM2 etc.) then push the Open[O] button to
open COM port, If success to connect the PIP900 modem, you can change to the Test
Transmit dialog to test the modem transmit functions.
c. In Test Transmit dialog, select Power Level 4(Max) in functions window. You may
change Modulation kinds and Transmit Duty value then select Send button to send
command to PIP900. (Note: items means in the Modulation kinds, only 1 means positive
frequency deviation, only 0 means negative frequency deviation, center means center
frequency, PN9 scramble means use PN9 modulation data, dynamic frequency use to test
dynamic frequency deviation)
d. The continuous transmission of a modulation carrier (PN9 modulation or dynamic
frequency with fixed Data modulation) for longer periods when you set the Duty_off
to 0. but you can’t change the parameters again in this mode, till you reset the
pip900 modem(by power down).
e. The item others may not use.

FCC Part 2 certification requires all integrated products to have
routine environmental evaluation for radio-frequency (RF) exposure
prior to equipment authorization or use in accordance with FCC rules
2.1091 and 2.1093 and FCC Guidelines for Human Exposure to Radio
Frequency Electromagnetic Fields, OET Bulletin 65 and its
Supplement C.
For “mobile or fixed devices”, defined as transmitting devices
designed to be generally used such that a separation distance of at least
20 cm is maintained between the body of the user and the transmitting
radiated structure, Maximum Permissible Exposure (MPE) limits may
be used with field strength or power density limit of 0.597 mW/cm2 (at
896 MHz).
"To satisfy FCC RF exposure requirements a separation
distance of 20 cm or more should be maintained between the
antenna of this device and persons during device operation. To
ensure compliance, operations at closer than this distance is not
recommended."
“Regulatory Notice of Compliance
This equipment has been tested and found to comply within 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.”
