To remove an MMC 
1. Open the card compartment door by unscrewing the thumb screw. 

The screw should only be finger tight. If it was over-tightened, use a 

thumbnail, a coin or a screwdriver to open the door. 
2. Just press a finger against the label of the MMC and drag it from the 

slot. 
3. Close the compartment door and fasten the thumb screw finger tight. 
To add an MMC or SD Card 
1. Open the card compartment door. 
2. Grasp the bottom of the MMC and push the top of the card into the 

slot. Once the card is started, use your fingernails to slide it the rest of 

the way to the left, until it is firmly seated in the slot. 
3. Close the compartment door and fasten the thumb screw finger tight. 

Cleaning Towel 
A lint-free microfiber towel is included for cleaning the unit’s screen. 

The towel is highly effective in clearing away water spots, smudges and 

finger prints. Just wipe the screen with the dry towel — it's not neces-

sary to moisten the towel with water. If the screen is badly soiled, you 
may use water or common window or lens cleaners. However, DO NOT 

use polishing compounds or any other abrasive product.  

If you lose the towel or wear it out, you can replace it with a similar 

microfiber cloth. These are often available where shop towels or auto-

mobile cleaning towels are sold.
