When you install an IFB or ISO option cable and set the internal DIP switches as noted in the following para- graphs, specific front panel buttons will be reserved for the installed option. The button insert sheet provides standard button labels for these reserved buttons. See "Front Panel Button Inserts", page 17 for details.
DIP Switch Settings Unless you are using the 803 for IFB or ISO operations, you will probably not need to change any of the DIP switch settings. However, briefly review the tables below and make any required or optional changes before pro- ceeding.
(The setup mode features are described starting on page 43.) Key code switch settings are as follows: 0: No access permitted (no one can program the 803) 1-9: User must enter this number before accessing setup mode A-F: No restrictions on access to setup mode (default) Note: The key code switch has a stop at the 0 setting.

43) could erase your programmed settings. The 803 has two reset modes: cold reset and warm reset. A cold reset restarts the 803 and erases all setup mode pro- gramming. All front panel buttons are turned off (except the SPK ON button, which always starts up in the on posi- tion).
Note: If the mounting location for the 803 provides access to the back panel controls and connectors, you should be able to mount the 803 at this time. Otherwise, perform the connections and adjustments as described in the following sections before mounting the 803.
If you are connecting a powered channel, termination is usually accomplished by the power supply. The 803 has built-in dc isolation, and so it is not neces- sary to use isolation capacitors when connecting to a pow- ered intercom channel.
The two com- mon connections for each relay are electrically identical. All relay connections are electrically isolated from the rest of the 803 circuitry. Relay connections are also avail- able at J108, page 28. External Switch Contact Input (XSW) A switch may be connected between pins 13 and 38 for re- mote operation of a front panel button.

To change this, see "Mic Select Setup", page 48. The IHM gain is adjusted via the IHM trimmer on the back panel. The standard 803 uses a 5-pin connector for J202. This connector is used for headsets without a mic switch.
Connect the intercom channel to the remote listener's station. When connecting both local IFB channels and standard intercom channels to the 803, it may be convenient to use splitters. An example for 2-wire ap- plications is shown in Figure 22, page 42. For a 2- wire IFB channel, use the appropriate pins at the J101 connector, page 21.

MRT-327 intercom stations conference on channel 1. Channel 2 of each intercom station communicates with the 803 on a private channel. The PS-31 provides power to the intercom stations on channel 1 and also provides the 200-ohm line termination for this channel. The 4012 provides a separate 200-ohm line termination for each of the twelve channels of the 803 that communicate separately with each intercom station.

Setup Mode Introduction Setup mode lets you access almost all of the programma- ble features of the 803 using the front panel buttons. This section describes each of these features. Reminder: Changing certain internal DIP switch settings (the ones that are grayed-out in Tables 2 and 3 on page 16) will erase all user programming that you configured in setup mode.
The MIC ON button also activates, so that the 803 user can talk to the caller with- out having to press any buttons. Default setting: off for all channels.
To quit setup mode tap the CALL & SETUP button. Note that you must quit, then re-enter setup to assign additional unused channels. 3.4.7 BUFFER RECALL Setup Buffer recall is a convenient way to assign the current on/off settings for all talk and listen buttons to any one of the PRE 1 through PRE 6 preset buttons.
CALL DISABLE Setup 3.4.9 This feature disables or enables call signal reception on se- lected channels. When call signal reception is disabled on a channel, there will be no chime tone or button flash to indicate an incoming call. Outgoing call signals are not af- fected.
IFB channel normally sends a program feed to a re- mote listener. By pressing the talk button for the local IFB channel, the 803 station operator can interrupt the pro- gram feed and then talk to the remote listener. If the IFB channel is configured as a 2-wire channel, either the pro- gram 1 or 2 input can be selected as the program source.
Page 48
*, 0, and # buttons will then display the program source being used with that button. 3.4.21 MIC SELECT Setup This feature selects which microphone inputs are acti- vated by the PANEL ON button in both the on and off po- sitions.
Enter setup mode (page 43). Tap the PRESETS button (TALK 11). The PRE 1 through PRE 6 preset buttons on the key- pad will start flashing. Tap any one of these buttons to select it. Talk and listen buttons that are currently assigned to that preset button will flash brightly.
Tap CALL & SETUP to exit. 3.4.36 VOX ENABLE Setup The 803 can be set for voice-activated microphone. When this feature is enabled the microphone will remain off when you are not speaking into it. When you do speak, the microphone will turn on, and your voice will be trans- mitted on any channels that have talk buttons activated.
ON-MIC HEADSET connector. PM (Internal Panel Microphone) This trimmer adjusts the gain for a panel microphone con- nected at the front panel of the 803. EXT HM (External Headset Microphone) This trimmer adjusts the microphone gain for a dynamic- or carbon-mic headset connected at J111.
Repeat the adjustment for each remaining channel that is being operated in 2-wire mode. This completes the null adjustment. If you will be using headphones with the 803, perform the sidetone adjust- ment after the null adjustment. 4.2.5 Sidetone Adjustment The sidetone adjustment lets you set the level of your own voice in the headphones when using a headset.
Intercom Operation Initial Volume Adjustment Prior to first use, set the MASTER VOLUME and PRO- GRAM VOLUME controls to the minimum position. Set the twelve channel LEVEL controls to about the half-on position. Later, you can adjust the individual channel lev- els up or down to balance channels that are unusually loud or soft.
The 803 is capable of generating DTMF tones for dialing out on a phone line. If there is a telephone interface con- nected on an intercom channel, you can use the 803 key- pad to dial out on that channel. The actual method that...
ISO operation. When you are using the 803 in VCP emulate mode, you can use the global reset feature of the 803 to shut off all ISO buttons in the system. To do this, tap the G-RST button on the 803 keypad.
