Motorola PMLN5641, PMLN5642 Surveillance Kit User Guide


Motorola Solutions


The PMLN5641 and PMLN5642 is a two-wire surveillance style accessory with one wire for listening through an acoustic tube and another separate wire for transmitting using an integrated microphone/PTT housing.

The Clear Acoustic Tube snaps on to the earbud for enhanced discrete communication. The integrated microphone/PTT comes with a clothes clip allowing you to wear it under your uniform for more discreet covert operations, yet giving the flexibility of hands-free communication.

Note: It is the user’s responsibility to ensure that the chosen accessory is suitable for his/ her intended use.


Attaching and Removing the Surveillance Accessory to the Terminal

  1. Always turn the terminal OFF before connecting the accessory.
  2. Firmly plug the accessory connector into the terminal accessory jack at the side of the terminal. Secure the connector with the captive screw (see Figure 1).

Exposure to loud noises from any source for extended periods of time may temporarily or permanently affect your hearing. The louder the radio’s volume, the less time is required before your hearing could be affected. Hearing damage from loud noise is sometimes undetectable at first and can have a cumulative effect.

To protect your hearing:

  • Use the lowest volume necessary to do your job.
  • Turn up the volume only if you are in noisy surroundings.
  • Turn down the volume before connecting headset or earpiece.
  • Limit the amount of time you use headsets or earpieces at high volume.
  • When using the radio without a headset or earpiece, do not place the radio’s speaker directly against your ear.
