Important Safety Instructions




Cordless phones such as this one require AC power to operate. When the power is off, you cannot make or receive calls using your phone. To be safe, you should also have a phone that does not need AC power to operate (not a cordless phone), so you can still make and receive calls if there is an AC power failure.

When AC power is lost, the phone loses the security access-protectioncode connection between the base and the handset. When power is restored, put the handset on the base briefly to restore this connection so you can use the handset.

Your phone operates on standard radio frequencies as allocated by the FCC. It is possible for other radio units operating nearby on similar frequencies to unintentionally intercept your conversation or cause interference. This possible lack of privacy can occur with any cordless phone.


You must use a Class 2

!power source that supplies 9V DC and

delivers at least 210 mA. Its center tip must be set to positive and its plug must fit the phone's DC IN 9V jack. The supplied adapter meets these specifications. Using an adapter that does not meet these specifications could damage the phone or the adapter.

• Always connect the AC adapter to the phone before you connect it to AC power. When you finish, disconnect the adapter from AC power before you disconnect it from the phone.

4.Exercise care in handling the battery pack in order not to short it with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and cause burns.

5.Charge the battery pack provided or identified for use with this product only in accordance with the instructions and limitations specified in the instruction manual provided for this product.

6.Observe proper polarity orientation between the battery pack and battery charger.



Thank you for purchasing the RadioShack 900 MHz Cordless Telephone. Your phone uses the 900 MHz band for less interference, clearer sound, and greater range than 46/49 MHz cordless telephones. Its headset jack means you can connect an optional headset for hands-freeconvenience.#


You can place the phone on a desk or table, or mount it on a standard wall plate or directly on a wall. Select a location that is:

near an accessible AC outlet

near a telephone line jack

out of the way of normal activities

away from electrical machinery, electrical appliances, metal walls or filing cabinets, wireless intercoms, alarms, and room monitors

away from other cordless phones

The base’s location affects the handset’s range. If you have a choice of several locations, try each to see which provides the best performance..

Your telephone connects directly to a modular telephone line jack. If your telephone wiring does not have a modular jack, you can update the wiring yourself using jacks and adapters (available at your local RadioShack store or online at, or have the telephone company update the wiring for you. You must use compatible modular jacks that are compliant with Part 68 of FCC Rules. The USOC number of the jack to be installed is RJ11C (or RJ11W for a wall plate jack).


To mount the phone directly on a wall, you need two screws (not supplied) with heads that fit into the keyhole slots on the back of the base. Drill two holes 315/16 inches (100 mm) apart. Then thread a screw into each hole, letting the heads extend about1/8 inch (3 mm) from the wall.

1. Plug one end of the supplied modular cord (long for a desktop or direct wall mounting, short for a wall plate) into the TEL LINE jack on the bottom of the base.

2. Insert the supplied AC adapter’s barrel plug into the DC IN 9V jack on the bottom of the base and route the adapter’s cord through the strain relief slot on the base.

3. Route the adapter and modular cords through the molded routing channels

on the back of the base as Modular shown here.


4. For a wall plate, plug the other end of the short modular cord into

the wall plate jack.

AC Adapter Cord

5.For a wall plate or direct wall

mounting, align the base’s keyhole slots with the wall plate studs or mounting screws and slide the base down to secure it.

6.For a desktop or direct wall mounting, plug the other end of the modular cord into a modular phone line jack.

7.Plug the adapter into a standard AC outlet.

The phone comes with a rechargeable nickel-cadmiumbattery pack in the handset, but not connected. Before using your phone, you must connect the battery pack, then charge it for about15–20hours.#

1.Press down and slide off the battery compartment cover in the direction of the arrow to remove it.

2.Lift the battery pack out of the compartment.

3.Plug the battery pack’s connector into the socket in the compartment (the connector fits only one way), then place the battery pack in the compartment.

4.Replace the cover.

To charge the battery pack, place the handset on the base. The CHARGE/IN USE indicator on the base lights. Recharge the battery pack when the handset beeps and TALK/BATT flashes. R


The EPA certified RBRC® Battery Recycling Seal on thenickel-cadmium(Ni-Cd)battery

indicates RadioShack is voluntarily participating in an industry program to collect and recycle these batteries at the end of their useful life, when taken out of service in the United States or Canada. The RBRC program provides a convenient alternative to placing used Ni-Cdbatteries into the trash or the municipal waste stream, which may be illegal in your area. Please call1-800-THE-SHACK(1-800-843-7422)for information onNi-Cdbattery recycling and disposal bans/ restrictions in your area. RadioShack’s involvement in this program is part of the company’s commitment to preserving our environment and conserving our natural resources.


Dispose of the old battery pack promptly and properly. Do not burn or bury it. See “Battery Safety Instructions” on Page 3 for additional information on proper battery handling.





If the CHARGE/IN USE indicator does not light when you place the handset on the base, be sure the battery pack and AC adapter are correctly and securely connected. Also, check the charging contacts on the handset and the base. If the contacts are dirty or tarnished, clean them with a pencil eraser.

When you first use the phone after charging or recharging the battery pack, the phone might not work and you might hear an error tone. Return the handset to the base for about 3 seconds to reset the security access-protectioncode.

If the battery pack becomes weak during a call, the handset beeps every 3 seconds and TALK/BATT flashes. When this happens, recharge the battery pack.

If TALK/BATT does not light and the phone does not work, recharge the battery pack. (The battery power might be too low to light TALK/BATT.)

About once a month, fully discharge the battery by keeping the handset off the base until TALK/BATT flashes. Otherwise, the battery pack loses its ability to fully recharge.

The handset loses its security access-protectioncode if the battery pack is completely discharged. Place the handset on the base to recharge the battery pack and reset the code.

If you are not going to use your phone for an extended period, disconnect the battery pack. This increases the battery pack’s usable life.

The supplied battery pack should last for about a year. If the battery pack does not hold a charge for more than 2 hours after an overnight charge, replace it with a new 2.4-volt,600 mAh battery pack with a connector that fits the socket in the battery compartment. You can order a replacement battery pack through RadioShack. Install the new battery pack and charge it for about15–20hours. If you have trouble replacing the battery pack, take the phone to your local RadioShack for assistance.


You can select either a high or low ringer tone setting on the handset while the phone is not in use. Lift the handset and press VOL/RING to hear the current ringer setting. Repeatedly pressVOL/RING to select the desired ringer setting.


Your phone is set for tone dialing. If you have pulse service, change the dialing mode. If you are not sure which type of service you have, do this test.


1.Lift the handset and listen for a dial tone.

2.Press any number other than 0

If the dial tone stops, you have touch-toneservice. If the dial tone continues, you have pulse service.

To set the dialing mode, hold down FLASH until the phone beeps and TALK/BATT flashes, then press# to set the phone to pulse mode orTONE/ to set the phone to tone mode.



To make a call, lift the handset and press TALK. To answer a call, simply lift the handset. Or, if the handset is not in place on the base, pressTALK or any number key,#, or . The TALK/BATT indicator on the handset and the CHARGE/IN USE indicator on the base light.

To end a call, place the handset on the base or press END. The TALK/BATT and CHARGE/IN USE indicators turn off. ±


The phone scans 20 channels (frequency pairs used between the base and the handset) and automatically selects a clear channel each time you make or receive a call.

If you hear other conversations or you experience difficulty hearing the conversation, press CHANNEL to select a different channel. TALK/BATT flashes and the handset beeps, followed by a brief pause as your phone searches for a clear channel. ±


To adjust the volume of the sound you hear through the handset during a call, repeatedly press VOL/RING.


You can quickly dial the last number you dialed. Lift the handset and press PAUSE/REDIAL when you hear a dial tone. ±


FLASH performs the electronic equivalent of a switchhook operation for special services, such as Call Waiting. For example, if you have Call Waiting, pressFLASH to answer an incoming call without disconnecting the current call. PressFLASH again to return to the first call. ±ý


Setting the Dialing Mode

If your phone system requires that you dial an access code (9, for example) before you dial an outside number, do not dial the access code.

The phone exits setting mode if a call or page is received, or if you press END.

If the battery power becomes too low, the dialing mode might reset to tone. If you are on a pulse line and cannot make a call, try setting the dialing mode to pulse.

Making and Receiving Calls

If the handset is too far from the base while the phone is in use, pressing END might not disconnect the phone. Hang up the handset on the base.

Selecting the Channel

If the handset is too far from the base, an error tone sounds and the channel might not change. Move closer to the base.

Using Redial

The redial memory holds up to 24 digits, so you can redial longdistance as well as local numbers.

The redial memory also holds pause entries (see “Entering a Pause” on Page 9).

The redial memory does not store a flash entry or any digits you press before FLASH (see “Using Flash” on Page 7).

Using Flash

If you do not have any special phone services, pressing FLASH might disconnect the current call.





If you place the handset on the base to recharge it while the headset is connected, be sure the handset seats properly.

You can use a handset holder (available from RadioShack) to hang the handset on your belt for greater convenience when using a headset.

Connecting a headset disconnects the handset’s earpiece and microphone.

VOL/RING on the handset also controls the headset’s volume.


Some special services require tone signals (such as bank- by-phone).If you have pulse dialing, you can still use these special tone services.

1.Dial the service’s main number. When the service answers, press TONE/ . Any additional numbers you dial are sent as tone signals. The phone’s dial mode resets to pulse when you make or receive a call.

2.After you complete the call, return the handset to the base or press END. The phone automatically resets to the pulse mode.


To send a page from the base to the handset or to locate the handset when the phone is not in use, press PAGE on the base. The handset beeps for about 1 minute. To stop the page, press any key on the handset, place the handset on the base, or pressPAGE on the base again.


You can make or answer calls with hands-freeconvenience using an optional headset that has a3/32-inch(2.5-mm)plug. Your local RadioShack store has a variety of headsets available.

To connect the headset, gently flip open the rubber headset jack cover on the side of the handset, then insert the headset’s plug into the jack. ±

With a headset connected, you can make or answer calls as usual using the keys on the handset.

When you finish using the headset, disconnect it from the handset and close the rubber cover to protect the jack.


You can store up to 10 phone numbers in memory, then dial a stored number by entering its memory location number. You can also dial a number stored in memory location number 1 by pressing SPEED DIAL. Each number can be up to 16 digits.


1.Lift the handset.

2.Press MEM. TALK/BATT blinks.


3.Enter the number and any tone and pause entries (see

“Using Tone Services on a Pulse Line” on Page 8 and “Entering a Pause” on Page 9). ±

4.Press MEM again, then enter the memory location number(09)where you want to store the number. A tone sounds to indicate that the number is stored.

To replace a stored number, simply store a new one in its place. Or, lift the handset and press MEM twice. Then press the memory location number(09)you want to clear. A tone sounds.


In some telephone systems, you must dial an access code (9, for example) and wait for a second dial tone before you can dial an outside number. You can store the access code with the phone number. However, you should also store a pause after the access code to allow the outside line time to connect. To enter a 2-secondpause, pressPAUSE/REDIAL. You can add more pause entries for a longer pause.


To dial a number stored in memory, lift the handset and press TALK. TALK/BATT lights. When you hear a dial tone, pressMEM and enter the memory location number for the number you want to dial.

To dial a number stored in memory location 1, press SPEED DIAL. You do not have to pressTALK when you press



For quick recall of numbers for special services (such as bank-by-phone),store each group of numbers in its own memory location.

Dial the service’s main number first. Then, when prompted to enter the number, press MEM and enter the number for the location where the additional information is stored.


If you store an emergency service’s number (police department, fire department, ambulance) and you choose to test the stored number, make the test call during the late evening or early morning hours to avoid peak demand periods. Also, remain on the line to explain the reason for your call.


Storing a Number in Memory

An error tone sounds and the phone exits the programming mode if you wait more than 20 seconds between keypresses.

Each tone or pause entry uses one digit of memory.

If you try to enter more than 16 digits, the phone beeps 5 times and exits the programming mode. Start over at Step 2 and enter no more than 16 digits in Step 3.
