Checking the Antenna, Reinitializing Omega | Telenetics OM-AMPS-100

Section 2 Contents

The voltage between the red and black terminals of the battery should be between +12.5 and +14.0 Volts.

Checking the Antenna

Make sure the antenna is securely fastened to the OMEGA cellular transceiver. Hand-tighten the antenna to ensure that it is securely connected to the transceiver. If it is, use the procedures under “Call Origination Testing” on page 22 and “Call Answer Testing” on page 23 to verify antenna operation.

Checking the Battery Voltage

If your OMEGA contains the Battery option, use the following procedure to check the battery operation:

1.Move the Battery Power switch to the OFF position (see Figure 1-1 on page 13).

2.Lift the AC fuse connector to remove AC power from

OMEGA.

3.Check the voltage between the red and black terminals at the battery (see Figure 1-1 on page 13). The voltage should be approximately +12.5 to 13.0 Volts. This is the Voltage output of the battery without the load.

4.Move the Battery Power switch to ON and check the voltage again. The voltage should be between +12.0 and 12.5 Volts with the load. If the voltage for the battery terminal is below 11.5 Volts, the battery will need to be recharged or replaced.

Reinitializing OMEGA

There may be times when you need to initialize OMEGA. For example, you may want to reinitialize OMEGA in hopes of obtaining better cellular reception.

To initialize OMEGA, press the Test button. This resets OMEGA and checks OMEGA’s receive cellular signal strength for approximately one minute. During this time, OMEGA is inoperable and cannot originate or answer calls.
