ET-410 DuoFone Cordless Telephone System
(430-0551A)                Troubleshooting            Faxback Doc. # 17894

We don't expect any problems with the ET-410, but if problems arise, try
these suggestions.

You have Interference from another Cordless Telephone

    - The ET-410 is available in four different operating 
      frequencies.  If there are interference problems from another
      cordless telephone in the neighborhood, the unit may be 
      exchanged for a different frequency unit within 30 days of the
      date of purchase.

Doesn't Work

    - Check the AC power and telephone connections to the Base Unit.
    - Be sure the antennas on both units are fully extended.
    - Make sure the Handset battery pack is charged.
    - The security code was not properly entered or has been lost.  
      Try entering it again following the sequence on page 15 of the
      Owner's Manual.
    - Make sure the TALK-HOLD-INTERCOM switch is in the desired
      position.
    - Be sure the POWER switch is set to ON.

You Hear a Series of Beep Tones from the Handset

NOTE:  When TALK PUSH HANG-UP is pressed, the security code is 
       transmitted from the Handset to the Base Unit.  If the Base
       Unit doesn't "recognize" the code the first time, the Handset
       will send the code several times before "giving up".  If the 
       beep tones sound and then the ET-410 works normally, this is 
       what has happened.

    - Out of communication range.  Move closer to the Base Unit.
    - The security code has not been entered properly or has been 
      lost; enter the security code following the sequence outlined
      on page 15 of the Owner's Manual.
    - AC power to the Base Unit has been lost; make sure the power
      cord is plugged in.

The Range is Shortened

    - Batteries are low.
    - Extend Base Unit and Handset antennas.
    - Re-locate the Base to a less shielded area.

You Cannot Receive a Signal

    - Out of range.
    - The security code has not been entered properly or has been
      lost; enter the security code following the sequence outlined 
      on page 15 of the Owner's Manual.

Telephone calls are automatically switched and routed through a complex
network of equipment.  Weak or noisy lines are occasionally encountered in
this network, and calls will sometimes have to be redialed.
