The REV-BP combines frequency agility and ease of use like no other. The transmitter operates within a 24 MHz wide segment in 25 KHz steps.  The high quality audio circuitry and advanced Radio Frequency (RF) signal processing offer broadcast quality signal-to-noise and audio clarity.  System features include:  •  Durable Painted Metal Case. •  TA-4F Audio Connector. •  Permanent Flash Memory for frequency/setting storage. •  On-Loc prevents accidental power off (when set). •  LCD Display for ease of viewing. •  Flexible quarter wave screw-on Antenna.

The Group will start     flashing. Use the up and down arrows to change the group number. Press     the SET button to save the Group.       After setting the Group, The Channel number will start flashing . Use the       up/down arrows to change the Channel number. Press SET and the      channel is now saved.       There are 10 Groups and up to 16 Channels (preferred groups/channels)       stored in memory. If desired, you can create new groups/ channels but      you must change to a new frequency to store in that group/channel.      In order to select a new frequency, you must have a “users” group            /channel selected. Press the SET button. The Group should be flashing.     Press the Up arrow until a group ending with u is found (any u group can      be used) Press SET. The Channel should now be flashing. Select a      channel with the up/down arrow. Press SET.      You are now ready to select a frequency to store in the users group      above. Press and hold the set and down arrows at the same time for 3       seconds and release to go to the next screen function.  8. The next screen displays the operating frequency of the group/channel.     If there is no frequency currently stored in the selected users      group/channel, a dashed line will be shown. Press SET. The dashed line      or frequency will start flashing. Press the up arrow one step at a time to      find the desired frequency or hold down the up arrow to scroll through      the frequencies quickly.

The next screen is the audio (microphone/instrument) level (attenuator)         screen. Setting the levels correctly depends on the microphone or         instrument used and the person using the microphone. Setting the       attenuator to “0”db is the same as setting a control to maximum gain.       Setting the attenuator to –42 db is the same as setting a control to       minimum gain. Each step of the attenuator equals 3 db.        Setting the attenuator for the maximum Audio Meter reading on the        receiver without peak distortion will produce the best signal to noise        ratio.          10. The next screen is RF Power. The Transmit Power (RF) is shipped set to         “Lo” for use with multiple frequency systems and the best battery life.         “Hi power can be selected for longer distances or to suppress noise or        interference. The nominal power in Hi is 50 milliwatts.  11.  The next screen is Voice or Guitar. The transmitter is shipped set to Voice. To select guitar when in the voice screen, press SET.
