CAUTION

43-103 7.fm Page 3 Tuesday, August 17, 1999 10:05 AM

Important: Cordless phones such as this one require AC power to operate. When AC power is off, you cannot dial out or receive incoming calls using your ET-537. For this reason, the E T537 should not be your only telephone. To be safe, you should also have a phone that does not need AC power to operate (not a cordless pho ne) so y ou can still make and receive calls if there is an AC power failure.

Warning: To prevent fire or shock hazard, do not expose t his product to rain or moisture.

RISK OF ELECTRIC SHOCK.

DO NOT OPEN.

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE COVER OR BA CK. NO USER-S ERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL.

This symbol is intended to aler t you to the p r es en c e o f un in su lated d an gerous voltage within the product’s enclosure that might be of suf ficient magnitude to constitute a risk of electric shock. Do not open the product’s case.

maintenance instructions are included in the literature accompanying this product.

READ THIS BEFORE INSTALLATION

We have designed your te lephone to conform to federal regulations, and you can connect it to mos t telephone lines. However, each device that you connect to the phone line draws power from the phone line. We refer to this power draw as the device’s ringer equivalence number, or REN. The REN is on the bottom of the base.

If you are using more than one phone or other device on t he line, add up all the RENs. If the total is more than five, your phone might not ring. In rural areas, a total REN of three might im pair ringer operation. If ringer operation is impaired, disconnect one of the devices from the line.

Note:

Some cordless phones operate at frequencies that might cause interference to nearby TVs and V CRs. To minimize or prevent such interference, the base of the cordless phone should not be placed near or on top of a TV or VCR.

FCC STATEM ENT

This telephone complies with Part 68

FCC Rules

of quest, provide the FCC Registration Number and the REN to your phone company. These numbers are on the bottom of the phone’s base.

You must not connect your phone to any of the following:

• Coin-operated systems

• Party-line systems

• Most electronic key phone systems

Note:

Your telephone operates on standard radio frequencies, as allocated by the FCC. Even though the access-protection code prevents unauthorized use of your pho ne li ne, it is possible for other radio units operating on similar frequencies within a certain area to unintentionally intercept your conversations and/or cause interference. This lack of privacy can occur with any cordless phone.

Modifying or tampering with the phone’s internal components can cause a malfunction and might invalidate its warranty and void your FCC authorization to operate it. If your phone is not pe rforming as it shoul d, take it t o your local Ra dioShack store for assistance. If the trouble is affecting the p hone lines , the ph one c om pany m ight ask you to disconnect your phone until you have resolved the problem.

43-103 7.fm Page 21 Tuesday, August 17, 1999 10:05 A M

REPLACING THE BATTERY

If you follow the instructions in “Charging the Battery” on Page 8, the supplied battery should last about one year. When the battery loses its ability to fully charge, you should replace it with a new one (available at your local RadioShack store).

Install the new battery as described below, then charge the battery (see “Charging the Battery” on Page 8).

1. While lifting up on the battery compartment cover’s latch on the back of the handset, pull the cover up to remove it.

2. Pull and lift the tab on the battery restraining strap to remove it.

3. Gently pull on the batte ry connector to disconnect it, then remove the battery.

4. Place the new battery inside the compartment.

5. Connect the battery’s wires to the connector in the compartment.

Note:

The battery’s connector fits into the connector inside the compartment only one way. Do not force it.

6. Replace the restraining strap and the cover.

Caution:

rechargeable nickel cadm ium battery. At the end of the battery’s useful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area. Some options that m ight be available are: municipal curb-side collection, drop off boxes at retailers, recycling collection centers, and m ail back programs.

Your telephone contains a

THE FCC WANTS YOU TO KNOW

In the unlikely event that your phone causes problems on the phone line, the phone company can temporarily discontinue your service. The phone company normally attempts to notify you in advance. If advance notice is not practical, the phone company notifies you as soon as possible and advises 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 this telephone. The phone company norm ally notifies you of these changes in advance, so you can take the necessary steps to prevent interruption of your phone service.

43-103 7.fm Page 22 Tuesday, August 17, 1999 10:05 A M

Your phone m ight cause TV or radio interference even when it is operat ing properly. To determine whether your phone is causing the interference, turn off and unplug your phone and disconnect the handset battery. If the interference goes away, your phone is causing the interference.

Try to eliminate the interference by:

• Moving your phone away from the receiver

• Connecting your phone to an AC outlet that is on a different electrical circuit from the receiver

• Contacting your local RadioShack store for help

If you cannot eliminate the interference, the FCC requires that you stop using your phone.

LIGHTNING

Your phone has buil t-in protection circuits to reduce the risk of damage from surges in phone line current. These protection circuits meet or exceed FCC requirements. However, lightning striking the phone l ines can damage your phone.

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