Microphone Operating

Instructions

Charging

Rechargeable batteries are pre-installed.

a.Turn off the HM-70 by sliding the ON/OFF switch all the way down and turn off the 705iR.

b.Connect one end of the charging cable to one of the CHARGE jacks on the back panel of the 705iR. Connect the other end of the charging cable to the charging jack on the side of the HM-70. The power indicator LED will glow green when the charging cable is connected and charging correctly.

c.The batteries fully charge in 8 to 12 hours. Once the batteries are charged, remove the charger cable from the HM-70.

NiMH batteries maintain their charge for a full day of normal classroom use. Always turn the HM-70 off when not in use.

Operation

The Channel A/B switch is located inside the battery compartment. The switch is set to Channel B at the factory.

a.Slide the ON/OFF switch on the side of the HM-70 all the way up. The power indicator LED will glow red and stay on. (There is a center MUTE position if you wish to leave power on but temporarily cease transmission of your voice.)

b.Do not adjust the audio gain adjuster that is located in the battery compart- ment. It has been preset by factory technicians and is not intended as a volume control.

Holding and Positioning

a.When holding the HM-70, grip the barrel in the center, silver section below the ON/OFF switch. Do NOT grip the HM-70 around the bottom, covering the black infrared sensors encircling the base. This interrupts signal transmission from the microphone to the receiver. Speak directly into the top of the microphone at a normal level, holding the head about 2 inches from your mouth, no lower than chin height.
