INTRODUCTION

INTRODUCTION

FEATURES

The Uniden®2.4 GHz cordless phones are designed and engineered to exacting standards for

reliability, long life, and outstanding performance.

Digital Spread Spectrum Technology utilizes a “wider frequency band” vs. a “single narrow band”

used in standard digital transmissions. The 2.4 GHz frequency range was recently released to

commercial communications. It provides secure conversation with the clarity of digital sound,

extended range, and reduced interference.

• 2.4 GHz Digital Spread Spectrum

• 30 Channel Autoscan

• 10-Number Memory Dialing

• Desk or Wall Mountable

• Tone/Pulse Dialing

• Handset Volume Control

• 32 Digit Redial

• Page/Find

• AutoTalk™

• AutoStandby™

• 6 Hour Talk Time

• 7 Day Standby Time

• Hearing Aid Compatible

The TRU 241 features include AutoTalk and AutoStandby.

AutoTalk allows you to answer a call by just removing the handset from the base so you don’t have to

waste time pushing buttons or flipping switches. AutoStandby allows you to hang up by simply

returning the handset to the base.

INTRODUCTION [ 1 ]

The UltraClear Plus™ true compander circuitry virtually eliminates background noise. This innovative

technology, together with 30 different channels, provides you with the best possible reception during

all your conversations.

To protect you against misbilled calls which might result from your phone being activated by other

equipment, the TRU 241 has Random Code™ digital security which automatically selects one of over

65,000 digital security codes for the handset and base.

Also, the AutoSecure™ feature electronically locks your phone when the handset is in the base.

To get the most from your phone, please read this owner’s manual thoroughly. Also, be sure to

complete the product registration form and mail it in.

INSTALLATION [ 5 ]

A continuous power
outlet is an AC
outlet which does
not have a switch to
interrupt its power.

Do not place the
power cord in an
area where it may
create a trip hazard
or become chafed
and create a fire or
electrical hazard.

Cleaning the Battery Contacts

▼

To maintain a good charge,it is important to clean all battery

contacts on the handset and base about once a month.

Use a dry cloth or pencil eraser, if necessary.

Do not use any liquids or solvents.

Selecting a Location

Before choosing a location for your new phone, there are some

important guidelines you should consider:

• The location should be close to both a phone jack and

continuous power outlet.

• Keep the base unit and handset away from sources of

electrical noise such as motors or fluorescent lighting.

• Be sure there is sufficient space to rotate the base unit

antenna to a vertical position.

Direct Wall Plate Mounting

If you don’t have a standard wall plate, you can mount your phone

directly to the wall. Before doing this, consider the following:

• Avoid electrical cables, pipes, or other items behind the

mounting location that could cause a hazard when inserting

screws into the wall.

• Try to mount your phone within 10-15 feet of a working phone

jack to avoid excessive cord lengths.

• Make sure the wall material is capable of supporting the weight

of the base and handset.

• Use #10 screws (minimum length of 1-3/8 inches) with anchoring

devices suitable for the wall material where the base unit will

be placed.

1. Insert two mounting screws into the wall, (with their appropriate

anchoring device), 3-15/16 inches apart. Allow about 3/16 of an

inch between the wall and screwheads for mounting the phone.

2. Refer to steps 1 through 9 as in the “Mounting the Base Unit on a

Wall” section. (See page 7.)
