I have the Garmin z30 how do i focus it on the flag and have the red text not blurry

Adjusting the eyepiece to focus the viewfinder, allows the Z30 to focus the optic per the steps outlined on our site here: Approach Z30 Manual - Adjusting the Eyepiece

The other factors to consider are the following: 

• Clean the front lens, and the eyepiece lens with the lint-free cloth provided with the Z30 to ensure the there are no smudging or debris over the lens pieces. 
• Ensure the disposable battery is working properly, 

Those needing further assistance after the suggestions above should contact Garmin Support to discuss with a Golf Specialist
