    If the headset connector is remotely located, allow space between this cable and interfering sources such as TV monitors, power supplies and equipment with internal power supplies. The Mode 56-16 power supply, when used, should be mounted at least 1 to 2 feet away from the Model 802 to minimize hum pickup.

    Model 802 - Series 4000 IFB The Model 802 may be used in either of two ways with the 4000 series IFB system. Method “A” uses a line level, unswitched microphone output from the Model 802 to drive Models 4001, 4002, or 4003 IFB Control Stations. Method “B” emulates either a Model 4001 or 4002 IFB control station and requires no external parts, but it does require: 1) the installation of one or two IFB option boards, 2) that mother board programming switch(es) be actuated and 3) a microprocessor reset be executed.

  • Page 45: Programming The Model 802

    FIGURE 38. Introduction There are two kinds of programming functions on the Mode 802: Hardware and Software. The hardware programming is accomplished via “dip switches” and by plugging in option boards. The software programming is accomplished via the front panel buttons.

  • Page 46: Dip Switches

    If, after entering the SET-UP mode, no button is pressed within 13 seconds, the Model 802 will exit or leave the SET-UP mode and return to normal operation. If, however, a selection is made, the unit will remain in SET-UP mode until intentionally exited.

  • Page 47: Relays Programming Function

    The CALL DISABLE (call signal receive disable) programming function is only enabled if the Model 802 is equipped with a Call Signal option. In a multiple Master Station system, all 802’s may not want to receive incoming CALL signals from all channels.

  • Page 48: Latch Disable Programming Function

    Programming the Model 802 LATCH DISABLE Programming Function The LATCH DISABLE programming function allows the latching action of any dual-action button to be disabled. This means a button can be programmed to function as a momentary action button only. A logical application would be when a TALK button is programmed to key a two-way radio transmitter.

    If an 802 unit, with any ISO options (H0, H1, H5), does not appear to have the global reset function, remove the bottom cover and check the revision letter on the mother board (AW3000-1). 802 units with mother boards having revision letters of “G” or less have not been updated.
