Use a mild detergent and a clean soft cloth to clean the body of the handheld. Do not use solvents, such as paint thinners. 

Use only a lint free cloth to clean the infrared port. Do not use detergents or solvents to clean the infrared port or display 

window. 

The Trimble Ranger handheld has a wide operating range of –5o F to 140o F; however, it is important to protect the 

handheld from extreme temperatures. Leaving the unit in a vehicle on the dashboard during a hot day or in a vehicle on a 

cold night can affect the Liquid Crystal Display (LCD) screen as well as cause battery drainage.

Only use the included stylus or other devices designed specifically for use with touch screens. The use of ballpoint pens, 

nails or other sharp objects to operate the touch screen will scratch and/or damage the unit. 

Do not apply any cleaner directly to the display. Do not use any abrasive cleaners. Abrasives may scratch touch screens. 

Keep the touch screen clean by gently wiping the display, using a soft cloth dampened by clean water. 

Use the screen protectors included with the unit to keep the touch screen clean and protected. To optimize the lifespan of 

the handheld touch screen, a new screen protector should be applied every 30 days.

The screen protector uses static to cling to the touch screen. The original screen protectors adhered to the screen with 

adhesive. 

To safely remove an adhesive screen protector without causing damage to the touch screen display:

1.  Use adhesive tape to start the lift of the screen protector. Stick the tape to one corner of the screen protector to 

start the lift. Do not apply the tape to the underlying touch screen. 

2.  Use your fingers to grasp the screen protector at the lifted corner and slowly peel back the protector to the 

opposite corner until removal is complete.

To apply a new screen protector:

1.  Clean the surface of the touch screen with water only if necessary. 
2.  Use a display cleaning cloth (included the screen protector kit) to clean and dry the touch screen before installing 

a screen protector. 

3.  Align the edge of the new screen protector with the corner of the screen and then drop the remainder onto the 

display. The screen protector uses static to adhere to the screen until it is removed and replaced.

IMPORTANT: 

•

Do not use sharp, metal or plastic objects to lift a screen protector. Micro-scratches can occur. 

•

Replace the screen protector every 30 days per the manufacturer’s recommendation.
