  • Page 3: Introduction

    introduction Congratulations on the purchase of your new Radium sound field system! With proper care and use it will become one of your most valuable classroom educational tools. Students will be able to consistently and easily understand the teacher, regardless of their location in the classroom, or competing internal or external background noise.

  • Page 5: Setup Tips

    IMPORTANT! Be sure you place your Radium speaker and transmitter units on their charger overnight – for a minimum of 12 hours – before turning the power on and/or using them for the first time. Failing to do so can reduce battery capacity.
  • Page 6 If placing the speaker on a table or surface top, consider the following: • Choose a location that provides easy access for the teacher, and is out of the way of students and main traffic areas. The speaker should be placed at least 6 feet/1.8 meters away from where the teacher stands.

  • Page 7: Setup Tips

    Make sure the table or cabinet is structurally solid, sturdy and out of the way of foot traffic. • Properly mount and securely fasten the T-bar speaker stand onto the bottom of the speaker. Make sure the stand is screwed on tightly, and that the speaker does not wobble when in an upright position.

  • Page 8: Daily Operating Tips

    • To operate using the internal battery as a portable system, simply unplug the speaker before use and plug back in after use – making sure you return power switch to ‘off’ position while plugged-in and charging. The battery takes 6 hours to reach a full charge;...
  • Page 9 Battery care and maintenance tips – • The speaker battery will last approximately 2 years depending on usage. • When not in use, leave speaker plugged into wall outlet with power switch in ‘off ’ position. • Keep speaker away from heating units – use/store in a cool dry place.
  • Page 10 daily operating tips (cont’d) Do not coil the microphone – since it also acts as your antenna, coiling or wrapping the cord will affect its range and may also reduce its life. Speak at a normal level – the system is projecting your voice for you.
