CHAPTER 10
MAINTENANCE INFORMATION
A. Caring for Your Q90 B. Recharging Batteries
Even though your Q90 TTY is built to last
and is designed to be maintenance free,
it contains sensitive and delicate
electronic parts. To protect your
investment and ensure the best
performance, treat it with care.
• Avoid dropping your Q90 or subjecting
it to any impact. Use the carrying
case when traveling.
•Clean your Q90 plastic case regularly
and use only a slightly damp, soft
cloth. To remove stains, use mild
soap. Never use detergents,
excessive water or harsh cleaning
agents.
• Do not allow dust to build up in the
gaps around the keys. Vacuum the
keyboard regularly. For best
protection, keep the dust cover on
when your Q90 is not in use.
Rechargeable batteries usually last
longer when they are used and
recharged regularly. For best results,
they should be completely drained and
then recharged every six months or so.
To drain the batteries, unplug the AC
adapter/charger, remove the telephone
line from the modular phone jack, turn
on the Q90 and use Ctrl F1 to select
the On Line condition. Leave the Q90
on until it automatically turns itself off.
WARNING...
DO NOT leave batteries drained of
power for more than 1 1/2 hours as your
conversation memory will be lost.
The batteries can normally be used and
recharged hundred of times. If they run
down quickly soon after charging, they
may need to be replaced.
NOTE: Before removing the batteries,
be sure to plug in the AC adapter to
avoid erasing the conversation memory.
