3. Rub the cotton portion of the cotton tipped applicator along the pins of the connector. Slowly move the
applicator back-and-forth from one side of the connector to the other. Do not let any cotton residue on the
connector.
4. All sides of the connector should also be rubbed with the cotton tipped applicator.
5. Spray compressed air in the connector area by pointing the tube/nozzle about ½ inch away from the surface.
6. Ensure that there is no lint left by the cotton tipped applicator, remove lint if found.
7. If grease and other dirt can be found on other areas of the cradle, use lint free cloth and alcohol to remove.
Cleaning Frequency
The cleaning frequency is up to the customer’s discretion due to the varied environments in which the mobile
devices are used. They may be cleaned as frequently as required. However when used in dirty environments it
may be advisable to periodically clean the ring scanners’ exit windows to ensure optimum scanning performance.

CAUTION Do not point nozzle at yourself and others, ensure the nozzle or tube is away from your face.
CAUTION Allow at least 10 to 30 minutes (depending on ambient temperature and humidity) for the alcohol to air dry
before applying power to cradle.
If the temperature is low and humidity is high, longer drying time is required. Warm temperature and dry
humidity requires less drying time.
