MAINTENANCE INFORMATION
A. Caring For Your TTY
Even though your DIALOGUE 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 TTY or subjecting it to any impact. Use the carrying case when traveling.
•Clean your TTY 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 TTY 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 and leave your TTY on until the product name is no longer displayed. Then turn your TTY OFF and plug the AC adapter/charger into an electrical outlet. It takes approximately 14 hours to fully recharge the batteries. You can use your TTY during charging. However, it will take longer to recharge the batteries.
The batteries should last several years. If they run down quickly soon after charging, they may need to be replaced.

Here are some commonly accepted abbreviations that eliminate the need to type long phrases.
GA means "Go Ahead". When you finish typing your sentence or message, type GA to show it's the other party's turn to respond. For example, HI, THIS IS JANE, HOW CAN I HELP YOU? GA When you see GA at the end of an incoming sentence or message, it is your turn to respond.
Q is often used instead of a question mark. For example, 
SK means "Stop Keying". Type SK when you are ready to end the conversation. Typing GA fol- lowed by SK is a polite way to say
NICE TALKING WITH YOU. GA SK.
Type SKSK to show that you’re hanging up. For example,
