Modem Mate

43-1242.fmPage 2 Wednesday, August 18, 1999 9:16 AM


Your RadioShack Modem Mate lets you use a fax machine or computer modem with almost any corded phone. It is a must for users of laptop computers, electronic notebooks, and data or fax modems.

It connects your modem or fax machine to the phone line using the handset cord, so you can use your computer even if the phone’s cord is not removable, or if the phone is on a key telephone system. Plus, you do not need to have an expensive modem jack installed. It also has connections for a tape recorder, so you can easily record your important phone calls.

The Modem Mate includes these features:

Compatible with Standard Handsets — works with almost any telephone that has a removable handset cord and does not have a keypad on the handset, including single-line, multi-line, and most digital phone systems.

High-Speed Operation — operates at speeds up to 14.4K bits per second.

Easy Call Recording — lets you easily record voice calls for later playback (requires a tape recorder).

If the Battery Test indicator lights dimly or does not light when you press Battery Test, replace the batteries with two fresh ones.


Use only fresh 9-voltbatteries.

Do not mix old and new batteries, different types of batteries (standard, alkaline, or nickel cadmium), or rechargeable batteries of different capacities.

If you do not plan to use the Modem Mate for an extended period, remove the batteries. Batteries can leak chemicals that can damage electronic devices.

Always dispose of old batteries properly.

7.With the phone’s handset still off the hook, give your computer or fax machine the command to dial the desired phone number.


The handset must be left off the hook when any data is being transmitted.

If you have trouble making a connection, set Level to1 (the lowest sensitivity setting) and try again. If you still have problems, try settingLevel to3 or4.

If the battery power is becoming weak, you might need to set Level to the next higher position.

8.When you finish the data transmission, hang up the handset, and set VOICE/MODEM back toVOICE.

You can connect a tape recorder to your Modem Mate to record and play back telephone conversations.


If the tape recorder does not have a 1/8-inchmicrophone jack, you need an adapter. RadioShack stores sell adapters for several different size plugs.

Batteries are not needed for recording and playing back telephone conversations.

You can only record telephone calls made from the telephone that the Modem Mate is connected to.

Important: It is illegal in some areas to record phone conversations without the consent of all parties to the conversation, including the phone company. For more information, check the laws in your area.

Your RadioShack Modem Mate is an example of superior design and craftsmanship. The following suggestions will help you care for the Modem Mate so you can enjoy it for years.

Keep the Modem Mate dry. If it gets wet, wipe it off immediately. Liquids might contain minerals that can corrode the electronic circuits.

Use and store the Modem Mate only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.

Handle the Modem Mate gently and carefully. Dropping it can damage circuit boards and can cause the Modem Mate to work improperly.


43-1242.fmPage 13 Wednesday, August 18, 1999 9:16 AM

Use only fresh batteries of the recommended size and type. Always remove old or weak batteries, which can leak chemicals that destroy electronic circuits.

Keep the Modem Mate away from dust and dirt, which can cause premature wear of parts.

Wipe the Modem Mate with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents.

Modifying or tampering with the Modem Mate’s internal components can cause a malfunction and might invalidate its warranty and void your FCC authorization to use it. If the Modem Mate is not performing as it should, take it to your local RadioShack store for assistance. If the trouble is harming the telephone lines, the telephone company might ask you to disconnect your Modem Mate until you have resolved the problem.


43-1242.fmPage 14 Wednesday, August 18, 1999 9:16 AM


In the unlikely event that your Modem Mate causes problems on the phone line, the phone company can discontinue your service. The phone company attempts to notify you in advance. If advance notice is not practical, the phone company notifies you of your right to file a complaint with the FCC.

Also, the phone company can make changes to its lines, equipment, operations, or procedures that could affect the operation of your Modem Mate. The phone company notifies you of these changes in advance, so you can take the necessary steps to prevent interruption of your phone service.

Your Modem Mate has built-inprotection circuits to reduce the risk of damage from surges in phone and power line current. These protection circuits meet or exceed FCC requirements. However, lightning striking the phone line or power lines can damage your Modem Mate.

Lightning damage is not common. Nevertheless, if you live in an area that has frequent electrical storms, we suggest that you unplug your Modem Mate during storms to reduce the possibility of damage.
