Battery Installation 

- See Figure 1

3 AAA 

•  Alkaline (LR03)

•  Lithium (L92)
•  Rechargeable NiCad or NiMH
Princeton Tec cares about the environment and recommends recycling 
batteries. For more information about battery recycling, please go to 
https://batterysolutions.com
Observe proper battery polarity. Improper installation of the batteries will 
damage the light and void the warranty.

WARNING 

!

•  Never mix fresh and used batteries.
•  Never mix different battery brands or chemistry types
•  Always remove drained batteries immediately.
•  Remove batteries during long periods of storage.

NOTE: Lithium batteries offer extended constant brightness time, 
extreme cold weather performance, and lighter weight. Rechargeable 
NiCad or NiMH batteries may result in reduced brightness due to lower 
nominal voltage.
The Vizz battery compartment has a waterproof seal. It is important to 
keep this seal free from dirt and away from harsh chemicals in order to 
preserve waterproof integrity. Inspect the seal every time batteries are 
changed. If dirt is present, wipe gently with a damp cotton swab and 
mild soap until dirt is removed.

Troubleshooting

If the Vizz fails to light: 

•  Check the batteries for proper installation.
•  Replace batteries if proper installation is confirmed.
•  Check circuit board for water (the seal may have be compromised by 

improper rear cover installation or dirty seal). The light will resume nor-
mal operation once the water is shaken or blown out and the light is 
left open until completely dry. If the light has been contaminated with 
salt water, flush the unit with fresh water and dry as described above.
