Important:
• Cordless phones such as this one
require AC power to operate. W hen
AC power is off, you canno t dial out
or receive incoming ca lls using your
ET-928. For this reason, the ET-928
should not be your only telephone.
To be safe, you should al so have a
phone that does not require AC
power to operate (not a cordless
phone), so you can still make and
receive calls if there is an AC power
failure.
• Some cordless phones operate at
frequencies that might cause interference to nearby TVs and VCRs.
To minimize or prevent such interference, the base of the cordless
phone should not be p laced near or
on top of a TV or VCR.

PREPARATION
CONNECTING AND
CHARGING THE BATTER Y
P ACK
The ET-928 comes with a rechargeable
nickel-cadmium battery pack in the
handset, but not connected. Before using your phone, you must connect the
battery pack, then charge it for about 24
hours.
1. Slide off the handset’s battery compartment cover.
2. Insert the battery pack’s
connector with its flat
side up into t he p hone’s
socket. The connector
fits only one way.
:
Notes
• You can hang the handset face up
on the base if it is wall-mounted
(using the slot on the back of the
handset); however, the battery pack
will not fully c ha rg e in th is po si tio n .
• When you first use your phone after
charging or recharging the battery
pack, the handset might not work or
it might sound an error tone when
you press
place the handset on the base for
about 5 seconds, then try again.
• If the CHARGE indicator does not
light when you place the handset on
the cradle, be sure the battery a nd
AC adapter are correctly and
securely connected.

To charge the battery pack, place the

Also, check the charging contacts
on both the handset and base. If the
contacts are dirty or tarnished, clean
them with a pencil eraser.

Page 12
43-109 8.fm Page 12 Tuesday, August 17, 1999 4:03 PM
• If the battery pack becomes weak,
the handset sounds a short beep
every 16 seconds during a call (or
every 64 seconds when the handset
is not in use) and the BATT LOW
indicator flashes. Within about 10
minutes, the phone will automatically disconnect. Recharge the ba ttery pack.
• If the battery pack loses its charge
completely or the base loses power
while the handset is away from it,
the security access-protection code
needs to be reset. To reset the security code, place the handset on the
base. If it was the handset that lost
power, leave the handset on the
base to charge the battery pack.
• About once a m ont h, fully discharge
the battery pack by keeping the
handset off the base until the BATT
LOW indicator turns o n. Otherwise,
it loses its ability to fully recharge,
and you might have to recharge and
replace it more often.

Storing a Pause
In some telephone systems, you must
dial an access code (
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 add one or more 2-secon d pauses to
a phone number you are storing in
memory, press
where a pause is needed.
Each pause entry counts as one

Testing Stored Emergen cy
Numbers
If you store an emergency service’s
number (police department, fire department, ambulance) and you want to test
the stored number, make the test call
during the late evening or early morni ng
hours to avoid peak demand periods. Also, remain on the line to explain the reason for your call.
USING THE INTERCOM
You can use the ET-928 as a two-way
pager and intercom between the base
and the handset. This is useful if the
handset is away from t he base and y ou
want to locate it, or if you want to have a
conversation between someone with the
handset and someone at the base.
:
Notes
Chain Dialing Service Numbers
You can make a call using more than
one of the ET-928’s memory locations.
This is called chain dialing. Chain dialing
is useful for dialing special services such
as alternate long distance or bank-byphone.
• If the handset is in use when it
receives a page, the hand set beeps
twice every 4 seconds.
• If a call comes in during an intercom
conversation, either of the intercom
parties can answer t he call, but the
intercom call is disconnected.

USING AN OPTIONAL
HEADSET
Your ET-928’s handset is equ ipped with
a headset jack on t op. This jack allows
you to connect an optional headset
(such as RadioShack Cat. No. 43-194)
for hands-free conversation — perfect
for when you are working in the yard or
garage. You must also have a handset
holder (such as Cat. No. 43-197, not
supplied) for the handset so you can
carry it with you while you use the headset.
Follow these steps to use a headset.
1. Place the ET-928’s handset in the
handset holder.
3. Place the headset on your head with
the earpiece over either ear and
adjust the microphone boom until it
is about even with your chin.
4. Clip the handset case on your belt.
