Troubleshooting
I cannot get a dial tone.
• First, try all the suggestions above.
• Move the cordless headset closer to the headset base. You
might have moved out of range.
• Make sure that the CORDED HANDSET CONNECTED switch is
set properly (page 8).
• Your telephone line cord may be defective. Try installing a new
telephone line cord.
• Another phone on the same phone line may be in use.
• If the previous suggestions do not work, disconnect the
headset base from the telephone jack and connect another
phone to that jack. If there is no dial tone on that phone
either, the problem is in your wiring or local service. Contact
your telephone service provider.
The battery does not charge.
• Make sure that the battery is securely installed in the
cordless headset.
• If the cordless headset is in its headset base but the
on the headset does not turn on, refer to The
headset is off while charging in this Troubleshooting guide.
• Charge the battery in the cordless headset for at least three
hours. For optimum daily performance, return the cordless
headset to the headset base when not in use.
• You may need a new battery. Refer to the Battery charging
section on page 9.
• Your headset might be defective. Refer to the
Limited warranty section on pages 60-63 for further
instructions.
