Cleaning The 6739I Touchscreen - Aastra 6739i User Manual

Cleaning the 6739i Touchscreen

Repeated use of the 6739i touchscreen may lead to a dirty screen. To clean the phone's screen, Aastra recommends the
use of a super fine cotton cloth, cotton swab, or microfiber lens cloth made of microfiber suede (preferably one without
sewn hems or similar characteristics that would scratch the surface of the screen). You can use the cloth dry for dusting,
polishing and light cleaning, or dampen it (with water only) to deep clean the surface. If using a damp cloth, make sure to
use just a little water on the cloth. Too much moisture can cause damage to your phone that could be permanent. If the
cloth is dripping or the surface shows water spots after wiping, then you are using too much water on the cloth.
Some rules to follow when cleaning your screen are:
• DO NOT use any sharp objects including your fingernail.
• DO NOT rub, touch or tap the surface of the screen with sharp or abrasive items such as a ball-point pen or a screw
driver.
• DO NOT use any type of cleansers including abrasive cleansers.
• DO NOT use any type of glass cleaner or any cleaner that contains alcohol or ammonia.
• DO NOT spray any type of cleaner directly on the phone's screen.
• DO NOT allow any liquid to run down the surface of the touchscreen and under the bezel.
• If using a damp cloth, DISCONNECT power to the phone before wiping the screen.
Caution:
DO NOT use chemicals or sharp objects to clean your phone. Use of any type of cleaners, alcohol, ammonia, etc., and/or
hard or sharp objects can harm the touchscreen surface and potentially cause transparent conductive film cracks in the
screen.
To clean your 6739i touchscreen:
1. Disconnect power to your phone.
2. Get a soft cloth, such as a microfiber cloth.
3. If necessary, dampen the cloth. (for regular cleanings, a dry cloth is usually sufficient. For stubborn build-up,
or for periodic deep cleanings, get the cloth wet under the faucet and then wring out until it is just damp.)
4. Wipe the screen gently with the cloth making sure to not get any moisture in the sides of the screen. You
can also wipe down the entire phone to remove dirt and grime.
5. Allow your phone to completely dry after you are done cleaning. This should only take a few minutes
6. Reconnect power to your phone.
Note:
Keeping your touchscreen clean and free of dirt and fingerprints on a regular basis extends the life of your phone's
touchscreen
