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. Teachers can now speak all day in their normal voice without having to raise their voice to get their students??? attention.

Numerous studies show that classrooms using sound field enjoy better student comprehen- sion, increased student participation, better grades and fewer behavioral referrals.

Read this manual carefully to become familiar with your system and to get the most out of its many features and options.

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.

Basic setup tips

First ??? Identify a front corner of the room ??? the location from where the teacher normally teaches.

Second ??? Take a good look around, paying close attention to power outlet and other electronic equipment locations. Ideally, the speaker should be placed at a 5-foot distance from other elec- tronic equipment, such as computers or radios.

Third ??? Determine whether to mount the speaker on the wall as shown in diagram 1, or place it on a sturdy surface using the T-bar table

diagram 1

setup tips (cont???d)

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.

4

setup tips (cont???d)

???Choose a table or surface top that is sturdy.

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.

If mounting on the wall, consider the following:

???The power supply cord needs to reach the wall outlet. Make sure the power supply is within reach of the speaker from its wall-mounted position.

???The teacher should be able to reach the controls located on top of the speaker once it???s mounted. Once the volume is set at a comfortable level, the speaker power switch located on the lower right side of the speaker can be easily accessed by the teacher. Follow the instructions on page 28 for setting the volume at the proper level.

???Never mount the speaker upside down, or horizontally. The speaker unit must be mounted such that the controls are located at the top of the unit.

5

daily operating tips

In the morning ???

???Turn transmitter power ???on??? and put microphone on.

???Turn speaker column power ???on???. The speaker should remain plugged into a wall power outlet during the day ??? with the power in the ???on??? position. Turn power switch to the ???off??? position at night after each use. The internal battery is not being used while the speaker is plugged into a wall outlet.

???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; at full charge, the speaker column battery will last up to 8 hours unplugged.

In the evening after each use ???

???Turn transmitter power ???off???, and place it back onto the charging stand; confirm that the ???charge??? indicator light illuminates. Transmitters not in use should always be placed on the charging stand ??? this is their home base station.

???Turn speaker column power ???off???. Leave speaker plugged into wall power outlet, but confirm that the power has been turned ???off.???

daily operating tips (cont???d)

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.

???When using speaker battery power (unplugged from wall), always remember to return power switch to ???off??? position after use.

???Never mount/use speaker horizontally or upside down. Controls should be accessible from top of unit.

???Plan on buying new NiMH batteries for your transmitter every 12 months. Alkaline batteries can also be used as back-ups, however, the 923C charger will not recharge alkaline batteries. Never attempt to recharge alkaline batteries ??? this will cause damage to the unit and void the product warranty.

???Remember to charge all batteries overnight before initial use.

7

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.

10 setting FM volume

Follow steps 1 or 2 below to adjust FM volume setting to proper level. Two people are needed to set the volume level. It is difficult to hear your own voice and make adjustments to it.

NOTE: The average volume setting is in the 11:00 position (see photo), but may change depending on room acoustics and noise level.

1With a sound level meter - Take a level reading in the ???A??? setting in the center of the room during normal classroom activity, and another reading of the teacher's amplified voice (without the class activity). The level of the teacher's voice should be set between 10-15 decibels above room noise level.

2Without a sound level meter - First, ask someone other than yourself (if you are the teacher) to listen to the amplified voice and make volume adjustments. An ideal volume level is achieved when the listener can hear the amplified voice at a comfortable level and the vol- ume level from the speaker and teacher???s mouth is comparable. If you can hear yourself through the loudspeakers, the volume setting may be too high and should be decreased. 28
