CHAPTER 10
MAINTENANCE INFORMATION
A. Caring for Your Q90
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.
B. Recharging Batteries
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.
