Front Panel Features

Channel Selector and Operation Buttons

These buttons have two modes of operation: standard operating mode and program, or setup, mode. The printing on the face of each button indicates its function in standard operating mode; printing under each button indicates its setup mode function. (See Section 3 for operation and programming instructions.) An LED located above each button provides status information.

The MCE325 is factory pre-programmed for two-channel operation, with each channel having one talk and one listen button. However, the MCE325 may also be programmed so that each channel selector button controls both talk and listen for a single channel, permitting operation of up to four intercom channels. Additionally, users may wish to customize the identification of channels. With this in mind, a button kit has been supplied with the MCE325 to allow you to customize the button labeling to suit your particular application. Figure 1.11 shows the available button caps as well as some typical button configurations.

NOTE The standard buttons are opaque. As a result, the front panel LED’s may not be visible when viewing the MCE325 from a low angle (such as when it is mounted high in an equipment rack). As a remedy for this problem, clear buttons are available that allow the LED light to pass through. (Order RTS™ part no. 9000-2698-800)
