Nady Systems MRC-11X owner manual LOW Batteries Power Indication, Using the Belt Clip

LOW BATTERIES POWER INDICATION

As you use the unit, the battery icon’s elements will disappear one by one to show the remaining power. When only one element remains, replace alkaline batteries or recharge NiCad or Ni-MH batteries as soon as possible.

USING THE BELT CLIP

To use the supplied belt clip, insert the clip fully into the slot at the back of the radio unit. To remove the clip, press the top of the clip and slide it out. The belt clip needs to be removed before changing/installing the batteries for full access to the battery compartment.

USING EXTERNAL MICROPHONE/SPEAKER HEADSETS

The MRC-11X is supplied with an MHS-11XO headset for the driver. If the unit will also be used for driver/passenger communications, an optional second headset can be purchased for the passenger (see the Optional Accessories Ordering Form enclosed for more info re the choice of the premium MHS-11XC/O or the standard MO-1/MC-1 headsets). When the driver headset is plugged into the DRV jack on the unit’s top panel, it automatically disables the MRC-11X’s built-in Mic and speaker, and the headset must be used for all communication.

(Note: Always make sure the unit is off or the volume at minimum before plugging in the headsets and placing them on the head.)
