G2.1.1 Installation of a Radio into a Radio Ready ControlWave EFM
Radio Ready ControlWave EFM Electronic Flow Meters contain all the hard-ware
required (except the radio and securing hardware) to accommodate installation and
operation of the radio option.
1. Open the Instrument Front Cover.
2. Remove the Radio Mounting Bracket by removing the two 10-32 x 3/8 Pan Head Screws
that secure it to the Fabrication Panel.
3. Using the mounting hardware provided with the radio, mount and secure the radio to
the Radio Mounting Bracket removed in step 2 (see Figures 1 & 2).
4. Re-install the Radio Mounting Bracket to the Fabrication Panel using the two 10-32 x
3/8 Pan Head Screws that were removed in step 2.
5. Connect the radio’s RF cable to the radio. The other end of the radio’s internal RF cable
should already be installed onto either a Polyphaser or a RF Bulk Head/Antenna
Interface connector.
6. Connect the user supplied antenna cable to either the Polyphaser or Bulk Head antenna
cable connector jack on the bottom of the ControlWave EFM (see Figure 3).
