Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning. 4.Do not use this product near water (for example, near a bath tub, kitchen sink, or swimming pool). 5.Do not place this product on an unstable cart, stand, or table. The product may fall, causing serious damage to the product. 6.Slots and openings in the cabinet and the back or bottom are provided for ventilation. To protect it from overheating, these openings must not be blocked by placing the product on the bed, sofa, rug, or other similar surface. This product should never be placed near or over a radiator or heat register. This product should not be placed in a built-in installation where proper ventilation is not provided. 7.This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your dealer or local power company. 8.Do not allow anything to rest on the power cord. Do not locate this product where the cord will be abused by persons walking on it. 9.Never push objects of any kind into this product through cabinet slots as they may touch dangerous voltage points or short out parts that could result in a risk of fire or electric shock.

In addition, by docking your cellular phone in the Base Unit adapter/charger, you can use any system Handset or the Base Unit to make calls using your cellular line. This is an excellent opportunity to take advantage of the liberal ‘nights and weekends’ or ‘unlimited’ calling plans your cellular provider may offer. Using additional Handsets, several people can be using the cordless system at the same time. Some examples: • One Handset on a call on the HOME Line; another Handset on a call on the CELLULAR Line; while a third Handset is in Intercom mode with the Base Unit. • Two Handsets conferenced on a HOME Line call; while an additional Handset is on a CELLULAR Line call. • One Handset in a three-way conference with the HOME and CELLULAR Lines; while two other Handsets are in Intercom mode. To order additional system Handsets (model# VT20-2439), battery packs, or headsets, call VTech Communications Inc at 1-800-595-9511. MENU DRIVEN DISPLAY The VT20-2437 Handset features a user-friendly display, making it easy to access the many features of this multi-Handset, cordless system. The three black keys, found directly below the LCD screen, are called soft keys. They are called this because their functions change depending on what you're doing-making a call, reviewing Caller ID, adding a name and number to your Phone Book, etc. For example, when the Handset is in the idle mode, the LCD displays: In this case, the 3 soft keys access REDIAL, MENU and MEMORY. When the Handset is active, the LCD displays: In this case, the 3 soft keys access VOLUME, HOLD and MUTE.

FCC Part 15 Warning: Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. The equipment has been tested and found to comply with part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try and correct the interference by one or more of the following measures: •Reorient or relocate the receiving antenna. •Increase the separation between the equipment and receiver. •Connect the equipment into an outlet or on a circuit different from that to which the receiver is connected. •Consult the dealer or an experienced radio/TV technician for help. Additional Information 43 FCC and IC Regulations FCC and ACTA Information If this equipment was approved for cornection to the telephone network prior to July 23,2001, it was registered with the Federal Commissions (FCC) in accordance with Part 68 of its rules. If the equipment was approved after that date, it complies with the Part 68 rules and with Technical Requirements for Connection of Equipment to the Telephone Network adopted by the Administrative Council for Terminal Attachments (ACTA). We are required to provide you with the following information. 1.

Maximum Permissible Exposure (MPE) Compliance Statement, FCC Radio Frequency Exposure Limit 1.1310 Health Canada Safety Code 6 Vtech VT20-2437 Wireless Telephone Base. The VT20-2437 wireless telephone base has been tested and the performance characterized in accordance with the MPE requirements of FCC 47 CFR and RSS 102. At an operating frequency of 2.4 – 2.4835 MHz the MPE limit for the General Population/Uncontrolled Exposure is 1.0mW/cm 2 . The VT20-2437 complies with this limit at the following line of sight distances from the antenna element: VT20-2437 : 4.6 cm The analysis is provided below. Power Density (P D ) = EIRP/(4πR 2 ) , Therefore, R≥√EIRP/P D 4π Using this calculation, for the VT20-2437 P D = 1.0 mW/cm 2 Antenna Gain = 0dBi, therefore EIRP = 24.2dBm or 263mW(max. worst case) R= 4.6cm The User Manual, which also incorporates the user instructions, includes a safety statement that cautions the user to ensure the Base Unit is located such that people will not approach within 5cm of the Base unit antenna. This distance provides additional safety margin for the product. Analysis provided by Nemko Canada for Vtech Engineering Glen Westwell.
