LYNX.sc E1 FAMILY
SPREAD SPECTRUM RADIOS

accordance with Section 3.7. Verify the polarity and the absolute voltage on all pins. Verify
ground connection for power.
7. Connect power to the LYNX.sc radio. Verify that the Front Panel “ON” LED indication is
illuminated. This confirms that power has been properly applied.
Ensure that the RF Antenna port connection is properly
terminated before applying power to the LYNX.sc terminal, as in
step 3.
When the LYNX.sc radio is initially powered-on, some alarm
conditions may be present. This is normal and alarms can be
ignored at this time.
8. Place a voltmeter across the GND and PWR front panel test points. See Figure 3-16 and 3-
17 for voltage setting information and Table 3-C for typical output power levels for given
cable lengths where EIRP limits apply. If necessary, use a small screwdriver at the front
panel receptacle to adjust the output power of the local transmitter in accordance with the
path analysis calculations. The recessed potentiometer is rotated clockwise to increase
transmit output power and counter clockwise to decrease transmit output power. After
verifying correct setting of the transmit output power, disconnect the voltmeter. Place the
cover cap found in the installation accessory kit over the front panel receptacle.
The LYNX.sc radio requires professional installation. With some
LYNX.sc models, in certain countries, there may be Effective
Isotropic Radiated Power (EIRP) limits which dictate the
maximum output power that the LYNX.sc radio can transmit given
the transmission line loss and the gain of the antenna. Consult
with appropriate government agencies or Western Multiplex if
there is any question regarding maximum output power allowed.
In the USA, 5.8 GHz models may be operated at full power. 2.4
GHz models may require a power reduction of 1 dB from +30 dBm
input power, as measured at the antenna feed, for every 3 dB that
the antenna gain exceeds +6 dB. See Section 3.3.3 and Tables 3-
C or 3-D for more details.
