TROUBLESHOOTING GUIDE
This section includes a list of frequently asked questions for problems you may encounter with your
ThermoDECT telephone. If your telephone is not operating as you think it should, check here before
arranging for servicing.
Problems turning on the telephone
“I cannot hear a dial tone or get the LCD display to work.”
Check to make sure the telephone is properly set up:
• Is the base unit plugged into the telephone line and AC power source? See page 6 for instructions.
• Is the AC power source turned on at the socket?
• Are the batteries properly installed in the handset? See page 6 for instructions.
If the problem persists, please contact our help line following the instructions on our website (www.
oregonscientific.com). Never attempt to repair or adjust the telephone yourself. This can cause damage
to the unit, electrical shock, and may invalidate your warranty.
Problems making and answering calls
“I cannot make or answer calls.”
• Try moving the handset closer to the base unit.
• If this doesn’t work, try a different position for the base unit following the instructions on page 6.
Typically, the higher you place the base unit, the better the reception.
• The battery charge level may be low. The battery life shortens when you use the Speakerphone
(handsfree) mode. Check the LCD display for the low battery warning signal
. If the battery is
low, place the handset in the charging cradle of base unit until the battery signal appears full.
• Check the power connection by switching off the power at the main socket, waiting a few
seconds, then switching it back on.
“When I press the phone button, I hear the busy tone.”
You will hear a busy tone if the line is engaged with another handset that is registered to the same base
unit. Check the LCD display area for the EXT symbol. This symbol indicates that someone else is
already on the line.
“When I press the keys on my handset, nothing happens. The display is showing the
symbol.”
The
symbol means that the keypad lock feature has been activated. Refer to page 23 for
instructions on how to unlock the keypad.
“When I press the keys on my handset, digits appear on the display but I cannot make an outside
call.”
• You may have inadvertently activated the call barring function on this handset, which prevents
calls from being placed.
• The handset may be unable to find the base unit. Try moving closer to the base unit. If the
problem persists, try a different position for the base unit, following the instructions on page 6.
• If you have registered additional handsets to the same base unit, make sure they are not already
on a call. The LCD display on your handset will display the EXT symbol if the line is engaged.
• The dial mode setting may be incorrect. Refer to page 10 for instructions on how to set the dial
mode.
“My call was cut off when I went out of range of the base unit. Now I cannot use my handset.”
Please move the handset closer to the base unit. You may want to consider moving the base unit to
achieve a greater transmission range. Refer to page 6 for instructions.
