Overview

1. Function Description
2. Important Technical Specifications
3. Usage Features
4. Maintenance Features

The provided document is a service manual supplement for the Panasonic KX-TC1466AGB and KX-TC1466AGW 900MHz Cordless Phones, specifically for the Argentinian market. This supplement, identified as Order No. KM40702683SE, Sup. No. 2, details changes from the original service manual, primarily focusing on compliance with the Restriction of Hazardous Substances (RoHS) Directive.

Function Description

The KX-TC1466AGB and KX-TC1466AGW are 900MHz cordless phones. The "AGB" suffix indicates a black version, while "AGW" denotes a white version. As cordless phones, their primary function is to provide wireless telecommunication within a limited range from a base unit connected to a landline. This allows users freedom of movement while making or receiving calls. The base unit serves as the charging station for the handset and the interface to the telephone network.

Important Technical Specifications

While the manual does not provide a comprehensive list of all technical specifications, it highlights several key details:

• Frequency Band: 900MHz, which refers to the operating frequency of the wireless communication between the handset and the base unit.
• Versions: Black (KX-TC1466AGB) and White (KX-TC1466AGW).
• Market: Specifically for Argentina.
• RoHS Compliance: A significant aspect of this supplement is the update of parts to comply with the EU Directive on the restriction of hazardous substances (RoHS), effective July 1st, 2006. This means that components containing lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers have either been eliminated or limited to allowed concentration levels.

The schematic diagrams provide insights into the internal electronics, including voltage levels and signal characteristics:

Base Unit (Main P.C.Board):

• Input: 1kHz, -15dBm, 390mVp-p (Tip).
• Output: -16dBm (at 600 ohm load, 40mA Loop current).
• RX_VCC: 80mVp-p (25.5 mVrms).
• TX_VCC: -16.5mVp-p (3.6 mVrms).
• LM324: An operational amplifier is used, likely for audio processing or signal conditioning.
• Various resistors and capacitors: Indicate filtering, impedance matching, and timing circuits.
• Antenna: Integral to the base unit for wireless communication.
• Keyboard Switch: For user input.
• Charge Terminal: For handset charging.
• Wall Mount Stand: Allows for flexible placement.

Handset (Main P.C.Board):

• Battery: Ni-CD (Nickel-Cadmium) is specified, though RoHS compliance might suggest a transition to Ni-MH or other battery types in later revisions, which is not explicitly stated as a change in this document.
• Input: 1KHz, 3.8mV (RMS) for the microphone.
• Speaker Output: 70mV (RMS).
• RX_VCC: 0.7-2.5V.
• TX_VCC: 0.7-2.5V.
• Crystal Oscillator: 4MHz, indicating the main clock frequency for the handset's microcontroller.
• Microphone and Ringer: Essential components for call functionality.
• Keyboard Switch: For dialing and menu navigation.
• LCD Panel: For displaying information.
• LED: For status indications (e.g., IN USE/LOW BAT).

RF Module (Base Unit and Handset):

• RX_VCO: 0.7-2.5V, 2.36V.
• TX_VCO: 0.7-2.5V, 1.8V.
• Signal Levels: Various RMS and p-p values are indicated for different stages of the RF signal path (e.g., 80mV RMS, 102mV RMS, 40mV RMS, 67mVp-p, 228mVp-p, 600mVp-p).
• Ceramic Filters: Used for frequency selection and noise reduction.

Usage Features

Based on the components listed and the nature of a cordless phone, the KX-TC1466AGB/KX-TC1466AGW would offer standard usage features:

• Wireless Communication: Freedom to move around while on a call within the base unit's range.
• Dialing: Via a keypad on the handset.
• Call Handling: Making, receiving, and ending calls.
• Ringer: Audible notification for incoming calls.
• Speaker: For listening to calls.
• Microphone: For speaking during calls.
• LCD Display: For showing caller ID, menu options, and other call-related information.
• Charging: The handset charges when placed on the base unit.
• Status Indicators: LEDs for "IN USE" and "LOW BATTERY" status.
• Wall Mountable Base Unit: Provides flexible installation options.
• Handset Locator Button: Likely on the base unit to help find a misplaced handset.

Maintenance Features

The service manual supplement is primarily for repair technicians and outlines several maintenance-related aspects:

• RoHS Compliance for Spare Parts: Technicians must ensure that replacement parts ordered comply with RoHS legislation. This is crucial for maintaining the environmental standards of the device. The document explicitly states that new parts are RoHS compliant.
• Detailed Parts Lists: Comprehensive lists of cabinet, electrical, and P.C. board parts for both the base unit and handset are provided, including part numbers and descriptions. This facilitates accurate identification and ordering of replacement components.
• Cabinet and Electrical Parts Location Diagrams: These diagrams show the physical placement of components within the base unit and handset, aiding technicians in disassembly, repair, and reassembly.
• Schematic Diagrams: Detailed schematic diagrams for the main P.C. boards of both the base unit and handset, as well as the RF modules, are included. These are essential for troubleshooting and diagnosing electronic faults at the component level.
• Accessories and Packing Materials List: This list helps ensure that all necessary accessories and packaging are accounted for during servicing or when preparing a unit for return.
• Professional Repair Requirement: The warning explicitly states that service information is for "experienced repair technicians only" and that "products powered by electricity should be serviced or repaired only by experienced professional technicians." This emphasizes the need for specialized knowledge and safety precautions during maintenance.
• No General Public Use: The manual is not intended for the general public, highlighting the complexity and potential dangers of self-repair for non-technical individuals.
