INTERCOM LINE LENGTH COMPENSATION (REAR-PANEL DIP

SWITCHES)

The receive circuits of the intercom channels have been optimized for an

intercom line length of up to 1,000 ft. (304.8 m). The capacitance of the

intercom line must be compensated for in the receive circuits if a good sidetone

null is to be achieved. When using a speaker, a good sidetone null is necessary to

achieve a usable listening level.

A set of two rear-panel DIP switches have been provided to compensate for lines

longer than 1,000 ft (304.8 m). Each intercom channel has its own DIP switch.

To change the setting of the line length compensation DIP switches, move either

the long line A or long line B DIP switch to the “on” position for intercom lines

longer than 1,000 ft. (304.8).

PROGRAM FEED ON ANNOUNCE

You can set up the announce feature so that program audio is sent out on the

announce line as well as the announce audio. You set this option up by using an

internal jumper on the circuit board.

To send out program audio along with announcements:

1. Please observe anti-static procedures. Static electricity can damage a circuit

card. Please ground yourself and tools before touching the circuit card.

2. Remove the cover of the RM-702 unit by removing the eight Phillips screws.

3. Locate the JP2 three-pin jumper on the centermost front portion of the circuit

card.

A jumper plug covers pins 2 and 3 of the jumper. This is the off position.

4. Remove the jumper plug from the pins and place it over pins 1 and 2. This is

the on position.

Program audio will now accompany the announce audio.
