Viking Universal Message Waiting Light

Introduction

The Viking Universal Message Waiting Light (Model VK-LM-1A) is designed to provide a visual indication of a waiting message on compatible telephone systems. This device illuminates a bright red LED when a message is present, offering a clear visual alert.

Important Note: This device is specifically engineered for use with PBX/Centrex type office telephone systems that provide a 90V message waiting signal. It is not compatible with standard residential phone lines or systems that use a "stutter dial tone" for message waiting indication. It also does not work with all AT&T phone systems.

Product Overview

The VK-LM-1A is a compact, wall-mountable unit featuring a single red LED indicator. Its simple design allows for discreet placement near a telephone.

Setup and Installation

The VK-LM-1A is designed for simple installation. Ensure your telephone system provides the necessary 90V message waiting signal for proper operation.

1. Identify Compatible Line: Locate a telephone line from your PBX/Centrex system that outputs a 90V message waiting signal. This is crucial for the device to function correctly.
2. Connect the Device: Connect the VK-LM-1A to the identified telephone line. The device typically connects in parallel with the telephone instrument. Refer to your telephone system's documentation for specific wiring diagrams for message waiting indicators.
3. Mounting (Optional): The compact design allows for placement on a desk or shelf. For a more permanent installation, the unit can be surface mounted using appropriate fasteners (not included) through designated mounting points if available, or by securing it with adhesive.
4. Test Functionality: After connection, leave a test message on the connected line's voicemail. The red LED on the VK-LM-1A should illuminate, indicating a waiting message. Clear the message, and the light should turn off.

Warning: Do not connect this device to standard residential telephone lines or lines that use stutter dial tone for message waiting, as it will not function as intended and may lead to misinterpretation of signals.

Operating Instructions

The Viking VK-LM-1A operates automatically in conjunction with your compatible telephone system.

• Message Indication: When a new voicemail message is received on the connected telephone line and your PBX/Centrex system sends a 90V message waiting signal, the red LED on the VK-LM-1A will illuminate. The light will remain on as long as there is an unread message.
• Clearing Messages: Once all messages are retrieved or cleared from the voicemail system, the PBX/Centrex system will cease sending the 90V signal, and the red LED on the VK-LM-1A will turn off.
• Incoming Call Indication: The device may also flash when an incoming call is present on the line, but its primary function is to indicate message waiting. Its behavior during incoming calls is secondary and depends on the specific signaling of your telephone system.

Maintenance

The Viking VK-LM-1A is designed for low maintenance. Follow these guidelines to ensure its longevity:

• Cleaning: Use a soft, dry cloth to wipe the exterior of the unit. Do not use liquid cleaners, aerosols, or abrasive chemicals, as these can damage the casing or internal components.
• Environment: Keep the device in a dry environment, away from excessive moisture, dust, and extreme temperatures.
• No User-Serviceable Parts: The VK-LM-1A contains no user-serviceable parts. Do not attempt to open or repair the unit, as this will void any warranty and may cause damage.
