Ringer Equivalence Number (REN)
The Ringer Equivalence Number (REN) is used to determine the number of devices that may

be connected to a telephone line. Excessive RENs on a telephone line may result in the
devices not ringing in response to an incoming call. In most but not all areas, the sum of
RENs should not exceed five (5.0). To be certain of the number of devices that may be
connected to a line, as determined by the total RENs, contact the local telephone company.
For products approved after July 23, 2001, the REN for this product is part of the product
identifier that has the format US:AAAEQ##TXXXX. The digits represented by ## are the REN
without a decimal point (e.g., 03 is a REN of 0.3). For earlier products, the REN is separately
shown on the label.

1. Introducing LG-Ericsson ACT-50

1.1 Overview

ACT-50 is a powerful communications tool for enterprises with LG-Ericsson iPECS
series (IP enabled communication systems). ACT-50 employs arrayed microphones
with high voice capturing capability and speakers with high voice reproduction
capability. In addition, it also incorporates a high-performance adaptive echo
canceller to eliminate interruptions of sound or drop in the voice level when multiple
talkers speak simultaneously. These features make your voice conference “easy to
talk” and “easy to hear”.

• Wideband voice codec technology delivers high fidelity audio from full

duplex speakerphone.

• Spot audio pickup function for better clarity.

• Microphone auto tracking function for noisy environment.

• Audio ports for use with softphone on PC.

2.3 Set-up

Before connecting your new device, take a moment to consider safety and reliability.
Use common sense when locating, connecting and using your ACT-50.

• Locate the device on a dry level surface. Keep the device away from the
edges of the surface to avoid the device falling off the edge.

• Locate cables to avoid damage. For example, do not locate under rugs or
carpet. Also, do not locate cables between the desktop and walls where they
may be crushed, damaging the insulation.

• Check the cables regularly and, if damage is discovered, disconnect the
device. Contact your local representative for a replacement.

• Should liquid spill on the device, disconnect the unit from power and the
network.

• Do not use during lightning storms. Lightning presents a rare but potential
lethal shock hazard.

• Clean ACT-50 with a soft dry cloth; do not use liquid cleaners or sprays.

• Only attach peripherals specified by LG-Ericsson.

• Always use caution when connecting to AC power. Use only with approved

AC/DC adaptor for the unit.

3.6 Settings

ACT-50 allows you to configure settings for various parameters. User can change
the following selections:

• Microphone mode

• Ring volume

• Date and Time, Location/Time Zone, SNTP time server

• Web GUI Password

• Syslog server

• QoS setup

3.6.1 Microphone mode

ACT-50 provides 3 microphone modes for various environments.

• : Zone mode is used for quiet environments and picks up audio from all
directions. {Basic mode}

• : Spot mode is used when the number of talkers is limited to one or two, or
when there is equipment that produces noise such as a projector nearby. ACT-50
fixes the audio pick up area to the front of the microphone by narrowing the
directivity. {Recommended for 1~2 users}

To specify the audio pick up area, use the numeric keys
in the “Microphone Mode” menu. When a key is
pressed, the areas in the direction of the pressed key
and the opposite direction is enabled or disabled. The
left illustration shows the areas enabled by pressing “2”
button.

Microphone indicators (blue LEDs) turn on to show the
direction where audio can be picked up.

ACT-50 User Guide

26

• : Tracking mode automatically tracks and focuses on the audio of the talker. The
audio can be picked up with narrow directivity so that other noises can be reduced.
This mode is suitable to pick up the audio clearly in a noisy environment. The voice
of only one talker can be captured at a time.

In the “Microphone Mode” menu, press a numeric
key to specify the area in which tracking is
disabled.

Every numeric key enables or disables the
tracking in the direction corresponding to the key
as shown in the following illustration. You can
select multiple areas at the same time. Pressing
“5” button enables microphone tracking in all
directions.

All microphone indicators (blue LEDs) turn on for the direction which audio can be
picked up.
