Push-to-Talk for Motorola M1 Radios

The CM-PTT-4MxM1 is a push-to-talk adapter built for Motorola portable two-way radios that use an M1 2-pin plug connector. It is designed for professionals who need hands-free transmission control while using compatible Point Source Audio in-ear headsets.

Plug-and-Play Operation

The unit requires no configuration or external power; it draws operating current directly from the radio’s accessory port. Its passive switching design adds no audible noise or thermal load to the headset or radio during normal use.

Questions about this item

How do I connect the CM-PTT-4MxM1 to my Motorola radio and CM-i3 headset?

Insert the M1 2-pin plug into the radio accessory port, then connect your CM-i3 or CM-i5 headset cable to the PTT unit's jack; no drivers or configuration are needed.

Which parts of the push-to-talk unit are likely to wear out first?

The tactile push button and the M1 2-pin connector pins endure repeated mechanical stress and are the typical service items over time.

What limits continuous transmission time during heavy use?

The radio's own duty-cycle protection and battery capacity govern maximum key-down time; the PTT itself is a passive switch with no thermal throttle.
