"I pressed the phone button several times, but keep getting the busy tone and cannot get the blue
LED light to display on the base unit."
Your handset may no longer be registered with the base unit. Unplug the AC power source from the
bottom of the base unit, then plug it back in. Press and hold the PAGE button until the blue IN USE
light flashes. Then, follow the instructions on page 16 to re-register your handset.
"I keep hearing a short beep on my handset, and the display is flashing the word 'Base'."
Your handset may temporarily lose its synchronization with the base unit due to radio interference in
your area. When this happens, you will hear a beep and see the word Base while the base unit switches
to another channel to overcome the interference. You can move closer to the base unit to help reduce
your telephone's susceptibility to radio interference. If you do not wish to hear the beep tone, you can
turn it off following the instructions on page 12.
Problems with multi-handset use
"I'm having problems registering a new handset."
• Sometimes it helps to unplug and then reconnect your base unit to its AC power source before
you start the registration procedure.
• Make sure you have selected a base number that is not already assigned. Choose a number that
does not have a [ ] check mark next to it.
• You may have already registered 5 handsets to the base unit. If so, you will need to remove
one or add another base unit before you can register the new handset.
• If you are replacing a faulty handset, make sure you have fully removed the faulty one before
registering the new one. Refer to the instructions on page 16 for more information.
• If you are still experiencing problems, you may need to reset all the registrations, then start over.
Refer to page 16 for instructions.
"I cannot make a call."
Only one outside call and one intercom call can take place at the same time. Make sure no one else is
already using the phone; if so, you will see the EXT symbol on the handset display area, and will hear
the busy tone when you try to place a call.
Problems with programming
"I changed the PIN, and I've forgotten the new one."
Please refer to page 14 for instructions on resetting the PIN number.
"I tried to register a new handset, and now all the handsets are flashing "Base" and I can not use the
telephone."
Reset your telephone, then try the registration process again. If you are still experiencing problems, reset
all your handsets and base units following the instructions on page 16, then re-register the handsets.
