Powering Up OMEGA
After making the connections described in the previous sections,
use the following procedure to power up OMEGA.
WARNING!
Do not remove the antenna from OMEGA and never apply
power to the cellular unit without the antenna attached. The
cellular transceiver may be permanently damaged by an
unloaded transmitter.
1. Before applying power to OMEGA set the Power Battery
switch to the OFF position and lift the AC fuse connector (see
Figure 1-1 on page 13).
2. Connect the red lead to the + battery terminal and the black
lead to the
−
battery terminal.
3. Apply the 90-277 VAC power source to OMEGA.
4.
Close the AC fuse connector and move the Battery Power
switch to the ON position (see Figure 1-1 on page 13).
5.
Verify that the LEDs react as shown below.
LED Status and Description
Power Steady green = normal operation. If this LED indicates a
different status, refer to the troubleshooting procedures on
page 27.
Status
Fast green blinking = strong cellular signal (-90 dB or better).
Slow green blinking = adequate cellular signal.
Fast red blinking = poor cellular signal.*
Slow red blinking = inadequate cellular signal.*
If the Status LED blinks red fast or slowly, it indicates a poor or unusable
cellular signal. In these cases, we recommend that you use an external high-
gain antenna, such as those available from Telenetics, to improve cellular
performance.
