Additional Safety Cautions
It is recommended that users’ and bystanders’ heads
be a minimum of 20 cm away from a unit’s
transmitting antenna when used in the basic
configuration. If the transmitting system is modified
from factory setup, check FCC regulations for
compliance with exposure limits.
Do not directly connect units via an RF cable without
enough proper attenuation. This will damage the
system.
Do not disconnect the antenna cable when the radio
has power applied. This will damage the RF
transmitter and void the warranty.
When the radio is operating at full power, the
maximum antenna gain allowed is 5.5 dBi per FCC
regulation part 15.
If there is no standard J1 cable attached to the J1
connector on the radio, a J1 power jumper plug
must be inserted. See Option 1, below.
Power Input
The SR-7100 radio module can be powered in two
different ways:
Through the Port Expander to J2. This power
configuration is recommended for the NCU and SCU
since these units are typically mounted at a high
elevation. With this configuration, the On/Off switch
on the Port Expander will turn the system on and off.
Through the J1 connector on the radio. This power
configuration is recommended for Remote Units
because they are typically mounted vehicles with a
DC voltage source. With this configuration, the
On/Off switch on the Port Expander will turn the
system on and off.
