Cordless phones start to ring true
From Changing Times, from Daily Press (Newport News, Virginia) May 20, 1985
Some of the problems with cordless telephones are the stuff of situation comedies: conversations accidentally broadcast on the radio or neighbors getting each others calls. Some are not so funny: hearing damage and pirates using owners’ numbers for long-distance dialing.
A cordless phone still shouldn’t be your only phone, but technological advances are beginning to ease some of the problems and quality phones with key features are becoming more affordable. A cordless phone is really a radio. Its base station plugs into a regular telephone jack, but airwaves carry a conversation between the base and handset. When not in use, the handset fits into a recharger to keep the batteries going.
Some of the new features include:
If you and a neighbor have cordless phones operating on the same frequency, or channel, you might get an annoying buzz on the line or accidentally receive each other’s calls. Stray signals from a CB radio or other device can also create false rings. With some new models, you can switch to another channel. Models without switchable channels must be returned to the manufacturer for a channel change.
To alleviate over-crowding, the FCC approved 10 new channels in December 1983. You can still buy a phone that uses channels in the 1.7-MHz frequency range, but all cordless phones manufactured after Oct. 1, 1984, must operate on the new 46- and 49-MHz channels.
Digital security codes
You can use these to prevent other cordless phone users from picking up your dial tone and making unauthorized long-distance calls. They also prevent neighbors’ calls from ringing on your line. Digital coding is more reliable than guard tone systems and is now available on many models. However, someone with an all-band radio, a scanner or another cordless phone can still eavesdrop. Don’t give out your credit card number or any other private information on a cordless phone.
Most of the short-range models are gone. These were designed to operate 50 or 100 feet from the base and suffered interruption due to static from low-level electrical sources, such as a refrigerator.
You no longer have to pay a premium for a phone with an extended range that provides clear sound up to 200 or 300 feet from the base station. The range is smaller where there are hills, electric motors or other sources of interference, or even nil if you live near a TV tower or an airport.
Many models claim a range of 700 or 1,000 feet, but don’t count on clear reception even if you live in an area with favorable surroundings. Compared with the 1.7-MHz chan-nels, the new 46-49-MHz channels are less prone to interference from electric motors, fluorescent lights and power switches, says Julius Knapp, an electronics engineer at the FCC.
Knapp told Changing Times the new channels should make it easier for companies to design better sound quality, but there’s no guarantee they will; quality still depends mostly on the manufacturer and model.
Most manufacturers have redesigned their cord-less receivers so the ringer doesn’t send loud blasts into your ear if you forget to switch it off when you answer. Some manufacturers, including Uniden, Pace, Cobra and Southwest-ern Bell, have new models with ring-ers on the back of the handset, away from the ear. A few other models protect the ear by ringing first at 25 per-cent of power and then getting louder with each successive ring.
Several cordless phones now have a home intercom system that lets someone at the base converse with someone using the handset. The Freedom Phone 1100 ($150) has a speaker at the base; others, such as Radio Shack’s Duofone ET-410 ($180), function as an intercom when a regular corded phone is connected to the base. When shopping, look for features you would want to get for any phone, such as automatic redial, memory dialing or two-line capability. Pulse-only, as opposed to tone dialing phones, usually cost less.
When manufacturers introduced the new 46-49-MHz phones last year, some 3 million older models still sat in stores and warehouses. Dealers have been offering them at big discounts. Many stores are out of the old inventory, but you can still find a 1.7-MHz model at half the price of one of the newer phones.
Some 1.7-MHz models cost less than $40, but you might have to pay at least $60 for a quality phone from a manufacturer that is still in business and handles repairs promptly. Features like switchable channels and digital security coding could bring the price to more than $100.
Dayna Ruliffson, president of Good Connections, a New Orleans retail store, told Changing Times the most popular high-quality older models include the Phone Mate 4210-4220, Electra Freedom Phone 4000 and several models by Pace.
Price cuts on older models have forced manufacturers to introduce phones in the 46-49-MHz range at prices averaging around $150. Mura is offering $5 and $10 rebates on its five 46-49-MHz models that range from $100 to $250. Expect to see higher prices and a greater number of new models to choose from in the near future, as soon as the 1.7-MHz models are sold off.
It’s quite possible that within the next five years the 46-49-MHz channels will become overcrowded, forcing the FCC to assign another new set of cordless phone channels. By then you might need a new phone anyway, because today’s phones, both cordless and corded, are made to last less than a decade, not the 20 years or so that rental phones were built for.
