Multi-Unit (MUC) / 6-slot Charger

MUC or 6-slot bank chargers are essentially radio battery chargers for multiple portable two-way radios. They are the power-up destination for multiple two-way radios and can charge all batteries equally at the same time. 

Bank chargers usually come with 6 slots, which means they can charge up to 6 radios at a time. Each MUC charger is compatible with different Motorola radio models, so you may check from our catalogue description to ensure you’re getting the right charger. 

If you only need to charge one two-way radio battery at a time, ATTACHE also carries single-unit rapid chargers specifically made for certain Motorola radio models.

PTT (Push to Talk)

Also known as press-to-transmit, PTT is a momentary button or switch on an earpiece that allows users to have conversations over two-way radios. This action will turn voice reception mode into transmit mode, allowing users to have instant communication and feedback with others. In many industries and fields, PTT on a two-way radio is regarded as the best form of communication and has played a vital role in streamlining interdepartmental communication.

3.   PMLN5732Designed with a boom microphone and in-line PTT, this lightweight Mag One earset allows the microphone to be placed near the mouth, ensuring exceptional audio transmission and hassle-free communication.  

Quick Disconnect 

Otherwise known as QD as its acronym, Quick Disconnect is an umbrella term for multiple kinds of connections that involve disengagement of parts. Quick Disconnect kits often come with several accessories that are detachable or can remain attached when not in use. This term covers several connections as follows:

  • Quick disconnect can be done between the cable and the earpiece itself. For different applications, a user can disconnect the earpiece from the cable and replace it with a different style of earpiece.
  • Transparent coiled acoustic tubes can be disconnected from the transducer (speaker) for cleaning, care & maintenance, or part replacement.
  • A user can also disconnect the cable from the radio connection point or adapter on the radio connection point.

Shoulder / Palm Microphone

Shoulder or palm microphone can refer to two types of radio accessories:

  • Speaker microphone – Most commonly used radio accessory across all industries. It comes in a size smaller than a human’s palm. This is usually clipped on one’s chest or shoulder epaulette when not in use; and held in one’s palm when in use.   
  • 2-wire earpiece (refer to 2-wire above) – A must-have piece for police, security and personal protection application due to its covert nature, 2-wire earpieces come with a microphone and PTT switch that is run down a wearer’s sleeve and held in the palm. 

1.  PMMN4076Featuring a 3.5mm audio jack, this IP54-rated windporting remote speaker microphone allows you to communicate clearly even in harsh weather conditions such as howling wind and heavy rain. Its windporting technology can prevent the howling sounds of the wind from transmitting across the microphone as well as prevent water from clogging the microphone, ensuring clearer transmissions at all times. 

2.  PMMN4040Certified as intrinsically safe, this IP57-rated windporting remote speaker microphone offers similar functions to PMMN4076 but with better water resistance. This audio-jack-free speaker can be submerged in up to 1 meter of water for at most 30 minutes. 

3.   PMLN7269This two-wire surveillance kit offers crystal-clear audio and a convenient push-to-talk button located right on the microphone. Users can either clip the microphone to their uniform or hold it in front of their mouth while speaking to it. 


Made of various materials such as brass, metal alloys and plastic, transducers are speakers in earpieces which allow you to hear incoming radio traffic. Out of the three materials mentioned, brass produces the highest audio quality, followed by the rest. While transducers are designed in an assortment of shapes and sizes, they are most commonly circular and as tiny as a penny in size.

3. PMLN6541This temple transducer headset has been designed to rest on users’ temples comfortably, so that they can still wear hearing protection in noisy environments or stay aware of sounds from their surroundings like fire alarms, machinery, busy traffic, etc.
