  1. Connect a headset to the beltpack.

  3. Select a Group. Press and hold the Mode button for 3 seconds until the “GRP” symbol is blinking on the LCD.Figure 1: Group Edit ScreenThen, use the Volume +/− buttons to select a group number from 0–51. Short-press Mode to save your selection and proceed to ID setting.IMPORTANT: Beltpacks must have the same group number to communicate.
  4. Select an ID. When “ID” begins to blink on the LCD, use the Volume +/− buttons to select a unique ID number. Press and hold Mode to save your selection and exit the menu.Figure 2: ID Edit Screen (Master ID)
    1. Pack IDs range from 00–04.
    2. One pack must always use the “00” ID and serve as the master pack for proper system function. “MR” designates the master pack on its LCD.
    3. Listen-only packs must use the “L” ID. You may duplicate ID “L” on multiple beltpacks if setting up listen-only users. (See the MicroCom 900M Manual for more information about that process.)
    4. Shared Talk beltpacks must use the “Sh” ID. You may duplicate ID “Sh” on multiple beltpacks if setting up shared users. However, the “Sh” ID cannot be used at the same time as the last full-duplex ID (“04”)


  • Talk – Use the Talk button to enable or disable talk for the device. This button changes with a single, short press. “TK” appears on the LCD when enabled.
    • For full-duplex users, use a single, short press to toggle talk on and off.
    • For Shared Talk users (“Sh”), press and hold while talking to enable it for the device. (Only one Shared Talk user can talk at a time.)
  • Volume Up and Down – Use the + and − buttons to control the volume. “VOL” and a numerical value from 00–09 appear on the LCD when volume is adjusted.
Multiple MicroCom Systems
  • Each separate MicroCom system should use the same Group for all beltpacks in that system. Pliant recommends that systems operating in proximity to one another set their Groups to be at least ten (10) values apart. For example, if one system is using Group 03, another system nearby should use Group 13.
  • Battery life: Approx. 8 hours
  • Charge time from empty: Approx. 3.5 hours
  • Charging LED on beltpack will illuminate red while charging and will turn off when charging complete.
  • Beltpack may be used while charging, but doing so may lengthen charge time.
