TROUBLE SHOOTING
If any problem should arise during operation of your TTY, go through the suggestions
listed below. Should the difficulty persist, contact AMERIPHONE or your authorized
dealer for assistance.
SYMPTOM CAUSE AND CORRECTIVE ACTIONS
Keyboard “Lock Up” - Q90 not
responding
Nothing happens when Q90 is
turned on
Batteries run down too soon after

No dial tone for keyboard dialing
Nothing happens after you dial
from keyboard
First hold down Ctrl Shift and ESC
simultaneously for about 2 seconds. Then,
if the Q90 still does not respond, discon-
nect the AC adapter and momentarily
remove one battery. This resets the internal
microprocessor.
No power. Check to make sure that both
ends of the AC adapter are firmly plugged
in. If you are using batteries, make sure
that each battery is properly installed and
that they are properly charged.
Batteries may not be charged properly. First,
completely drain the batteries by following
this procedure: Unplug the AC adapter,
unplug the telephone line, turn on the Q90.
Hold down Ctrl then press F1 to place
the Q90 on line. Leave the Q90 on until it
automatically turns itself off. Next, plug in
the AC adapter and the phone line and let
the Q90 charge for 14 hours. If this does
not work, your batteries may need to be
replaced. Replace with NiCad
rechargeable batteries.
NOTE: To avoid losing conversations
stored in memory, plug in the AC adapter
before removing the batteries.
Check to make sure both ends of the
telephone cord are firmly plugged in.
Make sure you press Return after
dialing the number. Pressing Return
completes the dialing sequence.
