tone.

To initiate the switchhook function, press and hold down TALK/HANG UP for 2
seconds.

ANSWERING A CALL

    indicator turns off.

SETTING THE VOLUME

people who are hearing impaired, or when you encounter poor lines or
especially noisy areas.  Simply set VOLUME to the desired listening level.

the call is still on the line.  To release a call from hold, press
TALK/HANG UP.

You can also continue your conversation from an extension phone on the same
line.  The call is released from hold whenever you pick up an extension
phone on the same line.

When you place a call on hold, you can disconnect the headset if you need
to step away from the phone.  When you want to continue your conversation,
reconnect the headset.  Then press TALK/HANG UP to release the call from
hold.

USING FLASH

FLASH provides the electronic equivalent of a switchhook signal, required
by some telephone services.

For example, if you have call waiting, you can put your current call on
hold and take another incoming call by pressing FLASH.  Press FLASH again
to alternate between the two calls.

NOTE:  If you do not have any special telephone services, pressing FLASH
       during a telephone conversation might disconnect your current call.

USING REDIAL

Each time you dial a number, the ET-152 Headset Telephone stores that
number into a temporary memory.  To dial the last number dialed, press
TALK/HANG UP, then REDIAL.

NOTES:  If you get a busy signal, you can press REDIAL again without
        pressing TALK/HANG UP.

        If the phone line has call-waiting or requires extra time to get a
        dial tone, one-touch redial might not work.  If so, press FLASH,
        then press REDIAL.

        The redial memory does not store a FLASH entry or any keys you
        press before FLASH.

        The redial memory holds 31 digits for tone dialing and 32 digits
        for pulse dialing.

USING TONE SERVICES WITH A PULSE LINE

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

With TONE/PULSE set to PULSE, press the asterisk (*) symbol at the point
where tone signals are required.  Any additional numbers you dial are sent
as tone signals.  TONE/PULSE automatically resets to PULSE when you hang
up.

NOTE:  You can set TONE/PULSE to TONE during the call at the point where
       tone signals are required.  If you do this, be sure to set
       TONE/PULSE back to PULSE when the call is over.
