Use & Care   
The headset’s arch fits around the back of the head just above the neck. The tip 
of the supporting arches rests on the temple just in front of the ear providing the 
necessary stability during use. The mic boom descends from the ear on the left side. 
Carefully loosen the boom by unscrewing the assembly one-quarter turn. Place the 
microphone capsule close to the mouth to a favorable audio position. Tighten the 
boom assembly. Bend the boom and headset slightly for optimum fit.  
Connect the Mini-XLR or 3.5mm plug of the microphone cable to the input jack of 
the bodypack transmitter or XM-10 phantom power adapter. When using a phantom 
power adapter, connect it to the microphone input of an audio preamp that provides 
phantom power.  
The entire HM-5U assembly has been moisture-proofed to guard against 
deterioration during use. After use in a high moisture application such as aerobics or 
a stage performance, remove the foam screen, wipe the headset with a dry soft cloth 
and permit it to air-dry. Do not store the unit in a closed space (e.g., a plastic bag) 
until all moisture has evaporated, and avoid conditions of extremely high humidity. 
This will help maintain the HM-5U’s excellent performance. While the HM-5U is not 
unusually sensitive to the outside environment, extremes in temperature can be 
harmful. Avoid, for example, leaving the microphone in direct sunlight for long periods 
of time.
