The ergonomically engineered spring clip grips firmly, holding the speaker mic securely in place, but easily movable with light finger pressure. The speaker design favors intelligible speech, being designed for optimum response at voice frequencies. The Big Red Button , a remote PTT accessory, connects to the ESM with a secure, threaded connector that's away from the Mic's quick disconnect and doesn't interfere. It can be ordered with the ESM or later, as an add-on. The pre-mounted, fixed radio cord, supplied as part of your ESM order, determines the unit Part Number.
Cords are available for most popular hand-held portable radios.
