SET-UP Set-Up & Daily Operation Operating the Flexmike Once the Flexmike is charged, follow these steps for use. 1. Remove the Flexmike from the charger and put it on by connecting the magnetic clasps behind your neck. Adjust the lanyard so that the top of the Flexmike aligns with the collarbone. 2. The Flexmike will automatically power on and mute when it is removed from the charger. 3. The microphone volume on the Flexmike is set at the factory to the midpoint.
Charging the Flexmike BEFORE USE, THE FLEXMIKE SHOULD BE CHARGED It will take 5-6 hours for the Flexmike to obtain a full charge. A fully charged Flexmike will last for up to 8 hours of use. If microphones are used daily, they should be charged each night. Replacement lithium polymer battery packs may only be purchased through Lightspeed Technologies (part # 77-L3.7V). Do not attempt to charge with other battery packs.
Using Flexmike as Wireless Audio Link Connect your computer into the USB-C jack on the bottom of the Flexmike to enable 2-way audio transmission (NOTE: USB-C cable not included). 2-WAY USB SET-UP & DAILY OPERATION Plug your external audio equipment, such as a computer, into the USB input on the bottom of the Flexmike 12 2-WAY USB AUDIO OUTPUT TIP: If your system includes two Flexmikes, you can use one mic for instruction and the second mic to transmit audio through the system.
Output Audio to Personal Assistive Listening Device (ALD) 1. Press the Audio Output Selector first, then turn the volume control on the front panel all the way down (fully counterclockwise). 2. Determine the type of audio input jack on the ALD as manufacturers’ products differ in connector size and shape. Many require a 3.5 mm to 3.5 mm patch cable (part# MSC3535, not included). 3. Connect a patch cable from the ALD microphone jack or AUX input to AUDIO OUT jack on the front of the 975. 4.

Troubleshooting PROBLEM: Low battery indication: Most problems are directly related to low battery power. Please run through the “Battery Check” items first. For remaining troubleshooting, use known good, fully-charged batteries. • Confirm that the white POWER light located on the front panel of the 975 is on. SOLUTION: Battery Check • Confirm that the microphone is turned on. There will be a solid blue light on the top of microphone to indicate it is powered on and ready.
Tips for Optimum Audio Performance • Speak in a natural voice. A normal conversational speech level will provide an adequate signal. It is not necessary to increase the intensity of your voice— the audio system provides adequate amplification (approximately 5–10 dB) above ambient room noises. • Avoid wearing jewelry that may rub or bump against the microphone. • Mute the Flexmike during private conversations with a student, parent, or other classroom visitor.
