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 speak all day in their normal voice, and will suffer far fewer vocal problems and absenteeism. 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 it’s many features and options. 1 3850 Radium216ug wnew FCC label 4/5/04 4:51 PM Page 7 2 understanding sound field and its benefits ? • distance • noise • echo • vocal fatigue cough! • distance • noise • echo • vocal fatigue ? without sound field with sound field 3850 Radium216ug wnew FCC label 4/5/04 4:51 PM Page 8 3 Before you set your system up, take a good look around your room. Where are the outlets located? Where are the computers and other electronic equipment? Where can you put your speaker so it's easy for you to reach, but out of the way of students and main traffic areas? Though each classroom is different, there are some general guidelines for speaker placement: The speaker should be at the front of the classroom at least 6 feet/1.8 meters away from where the teacher stands. Try to keep it at least six feet away from computers or other electronic equipment, since there may be interference if placed too closely together. installation tips 3850 Radium216ug wnew FCC label 4/5/04 4:51 PM Page 9 basic system guidelines To help ensure that you get the most from this system, we have put together a list of sug- gested guidelines. Charge transmitter batteries every night.Our rechargeable Nickel Metal Hydride batteries last approximately 12 hours between charges, but should be recharged every night so they are ready to go in the morning. Plan on buying new NiMH batteries after 12 months of use. Alkaline batteries can also be used, and they will last approximately 15 hours. NEVER attempt to recharge alkaline batteries! This will cause damage to the transmitter units and may invalidate product warranty. Charge the 920SR receiver batteries every night.The column speaker rechargeable battery lasts approximately 5 - 8 hours between charges, but should be recharged every night so it’s ready to go in the morning. For daily use, we recommend unplugging the power supply cord, allowing the battery to power the unit. Continuous, daily operation with the power supply cord plugged in will reduce the life of the battery significantly. Do not coil the microphone cord.Since it also acts as your antenna, coiling or wrap- ping 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. 4 3850 Radium216ug wnew FCC label 4/5/04 4:51 PM Page 10 5 accessories included with system 2 1 6 7 4 8 3 9 11 12 5 10 or or 3850 Radium216ug wnew FCC label 4/5/04 4:51 PM Page 11 6 10 channel changer screwdriver (330-3000-101) 6 receiver antenna (AT0831) 4power supply, receiver (040-7402-106) 9AA rechargeable NiMH batteries (AT0807) 5power supply, charging stand (040-7402-107) 8 elastic belt (AT0712) 1 column speaker receiver (920SR) 2 body-worn transmitter (921T) or handheld transmitter (922T) 3 charging stand (923C) 7 speaker table stand (AT0823) or wall mounting bracket (set of 2) (AT0820) 11 auxiliary input/output cable (AT0532-05) 12 auxiliary input cable (3.5mm – dual RCA) (300-6332-107) 3850 Radium216ug wnew FCC label 4/5/04 4:51 PM Page 12 7 920SR column speaker features (top) 2467 89 1 3 5 10 11 12 3850 Radium216ug wnew FCC label 4/5/04 4:51 PM Page 13 8 1 power, low battery, and reception status indicator for channel A 2 power switch and volume control for channel A 3 reception status indicator for channel B 12 aux output jack (3.5mm, mono) 4 power switch and volume control for channel B 8 antenna 11 aux input jack (3.5mm, mono) 7 aux output level switch See page 42 for level setting chart 5 tone control 6 aux input volume control 9 wall mount hole 10 extra antenna hole (not used) 3850 Radium216ug wnew FCC label 4/5/04 4:51 PM Page 14 9 920SR column speaker features (front and back) 13 14 15 16 17 20 18 19 3850 Radium216ug wnew FCC label 4/5/04 4:51 PM Page 15 10 14 two built-in speakers 16 handle 18 pow…

A Tune Up Procedure for the Radium 922T Xmtter 810-7403-102 3/19/04 A Init Release DT DATE REV REV RECORD AUTH 3880 Cypress Drive, Petaluma, CA 94954 CHECKED BY DATE Dave T APPROVED BY DATE Lee H REFERENCE ONLY Page 2 of 4 TITLE Tune Up Procedure for the Radium 922T Xmtter DWG. NO. 810-7403-102 REV. A General description - The 922T is a lightweight handheld microphone containing a built in transmitter. The dimensions of the 922T are approximately 2.1” in diameter by 9.3” in length. The 922T handheld transmitter is designed to be in compliance with Part 95 Subpart G – Low Power Radio Service 95.1009 (a) and (b). The intended use of this product is to support language translation and /or auditory assistance in an educational setting. There are two connection points, two adjustment controls and a battery/low power indicator. Connection points: Microphone input – The 922T has a built-in dynamic microphone. A nominal input level of -35 dBV RMS will correspond to +/- 5 KHz peak deviation The 922T employs an automatic level control circuit to limit the peak deviation to less than +/- 8 kHz. This circuit is further described in the operation section of this report. Battery Charger contacts - Two contacts at the base of the microphone are provided to charge the internal rechargeable batteries if so equipped. The charger is composed of a desktop stand, allowing up to two units to be placed in the charger. Due to the physical nature of the 922T charger, the user is discouraged from operating the transmitter while it is in the charger stand. In addition, the charger output current is limited and unable to provide adequate current to support the operation of the unit while it is in the charging mode. Adjustment controls: On/Standby/Off- This is a three position slider switch located on the side of the unit. In the “Off” mode, all power to the unit is disconnected. In the “Standby” mode all the circuitry is active, but all audio signals are muted, resulting in an un-modulated RF carrier. The purpose of this mode is to allow the operator to have private comments but keep the transmitter and receiver units in a ready mode allowing fast re-acquisition when the “On” mode is selected. Channel Selection - This model features frequency synthesized channel selection. The channel spacing is set at 50 kHz and the design is capable of operation using extra band channels 41 though 60 (except channel 50) as defined in Part 95.629 section (c) (2). The current model supports only a 16 channel selection switch, located on the side of the unit, and Phonic Ear has chosen channels 41-48 and 51-58 as its 16 primary operating channel frequencies. At no point is channel 50 used. Indicator – A dual colored LED indicator is located on the side of the unit. When the indicator is green the unit is powered up and ready for operation. If the indicator turns red, a low battery condition exists and the user must recharge the unit or replace the internal batteries. The low battery indicator is set to trigger at approximately 2.1 Volts giving the operator adequate time to change batteries or replace it with a fully charged unit. All the frequency determining devices and modulation controls are powered by an internal, well regulated DC/DC converter. If the operator keeps using the unit past the low battery warning, the unit will continue to operate within FCC limits until the battery voltage reaches of approximately 1.2 Volts and the DC/DC converter simply shuts off. The 922T consists of two PCB’s, board “A” and board “B”, and a DC-DC converter module. The unit is designed for high volume production and requires a minimum amount of tuning up and alignment. REFERENCE ONLY Page 3 of 4 TITLE Tune Up Procedure for the Radium 922T Xmtter DWG. NO. 810-7403-102 REV. A Tune up procedure: 1. Place a 200 mA current limited operating voltage of 2.5 volts +/- .1 volts to battery terminals of the DUT. 2. Move the power switch to standby mode and verify the operating current is 90 mA +/- 30 mA. 3. Verify the DUT power indicator is green 4. Check to see the 6.5V supply is 6.5V +/- .2 at L2 (board A). 5. Check to see the 3.3V supply is 3.3V +/- .1 at the junction of L7 and C41 (board B). 6. Verify there is less than 20 mV pk-pk AC ripple on either the 6.5V or 3.3V supply. 7. Next check for proper operation of the 12 MHz reference clock by placing the RF probe near R27, XL1. Correct the reference to 12 MHz +/- 60 Hz ( 5 PPM ) by adjusting tuning capacitor VC1 8. Set the channel selector to channel “48” or 216.375 MHz. Using a voltmeter, measure the PLL tuning voltage at the positive side of C34 (board B). Verify the voltage is 2.0 +/- .2 Volts. If needed, change the value of C46 to bring the PLL tuning voltage with in tolerance. If the initial tuning voltage is too high, lower the value of C46. If the tuning voltage is too low, increase the value of C46. A suggested increment value is .5pF. 9. Change the channel selector to channel “41” and check to see if the PLL voltage is 1.8 +/- .2 Volts. 10. Change the channel selector to channel “58” and check to see if the PLL voltage is 2.2 +/- .2 Volts. 11. The PLL should be locked, and the PA enabled. Verify the operating current is now 100 mA +/- 10 mA. 12. Using an RF probe, verify the RF output power is 10 dBm +1/-3dB at the antenna port (board B) next to L25. 13. Place the RF output to an RF FM modulation analyzer. 14. Verify the DUT has less than 20 Hz of RMS residual FM deviation ( 300-15 KHz BW ) bandwidth. 15. With no audio input, switch the power switch to the “on” position. 16. Adjust the pilot tone VR2 (board A) to produce 825 Hz +/- 75 Hz of deviation. 17. Switch the audio bandwidth on the FM modulation analyzer to 300 – 3 kHz. 18. Place a -35 dBV RMS, 1 KHz audio tone to the microphone input. 19. Adjust modulation adjustment VR1 (board B) to produce +/- 5 KHz peak deviation. 20. Switch the a…
