Caution! Exposure to Radio Frequency Radiation
The antenna shall be placed in a manner that minimizes the potential for
human contact during normal operation. To avoid the possibility of exceeding
the FCC radio frequency exposure limits, human proximity to the antenna
shall not be less than 20 cm (8 inches) during normal operation.
Prudence! L'exposition aux Rayonnements à Fréquence Radioélectrique
Pour respecter les limites FCC d'exposition aux fréquences radio (RF), les
antennes doivent être placées à 20 cm (8 po) au moins de toute personne.

Installation Overview
SECTION 1 INSTALLATION
1.1 Pre-Installation
Upon receipt of the access controller, inspect the carton for any external damage. If damage is
present inspect the SMHAP exterior for damage. Report any apparent damage to the shipping
agent and Lindsay Broadband sales office.
Pad values should be determined ahead of time. When calculating pad values allow for the
loss of the internal HFC interface; 5dB in the forward direction and 4dB in the reverse
direction. Forward levels at the modem should be 0 dBm. This is about 5 dBm at the input
port. For best return path S/N, the reverse pad should be selected so as to have the cable
modem operate near its maximum output level (-50 to -52 dBm). This will result in a level
around 47dBm at the input port. The testpoint indicates levels 20 dB below those at the cable
modem.
The cable modem can be provisioned ahead of time using the MAC address located on the
label on the outside of the power lid
1.2 Site Selection
The SMHAP must be mounted so that it has an un-obstructed view of the target area. The
SMHAP can obtain its power and RF connection from any nearby power passing tap, splitter,
or coupler. The SMHAP can consume up to 37W of power.
