tions before operating DoseMax. Ensure full compliance with ALL applicable laws and
regulations before and during use of this product.
About the battery
•The DoseMax contains a non-toxic lithium-ion battery with a high energy density, so it
is extremely IMPORTANT that you know how to handle it properly.
•NEVER recharge or use the DoseMax underground (mining) or in classified areas.
•The temperature range in which DoseMax can be recharged is from 0°C to 40°C.
Recharging your device out of this temperature range may reduce battery performan-
ce or shorten its life expectancy.
•Only use the charger that comes with DoseMax to recharge its battery.
About the use
•In regular use, ALWAYS use the microphone windscreen.
•It is recommended for the calibration certification to be renewed annually. For more
information, contact Inlite's Technical Support, through the website.
•In case of malfunction, need for repair, cracked or broken case or other visible
damage, stop using the instrument IMMEDIATELY, and contact the authorized retailer
where you purchased your DoseMax or Inlite Technology directly.
•NEVER use or store inside vehicles in hot weather, or expose it to direct sunlight.
Doing so, can cause the battery to heat up, reducing its life expectancy and/or
creating a risk of explosion.
!

•Be careful NEVER to expose it to strong impacts and shocks.
•DoseMax is not waterproof. NEVER submerge it in water.
•Periodically clean the DoseMax cabinet with a cotton cloth (NEVER immerse it in

•The temperature range in which the battery can be stored is from -20 °C to +45 °C,
and the temperature range in which the battery can be discharged is from -20 °C to
+60 °C. Using the battery out of this temperature range may reduce battery perfor-
mance or shorten battery life expectancy.
•If you see a performance drop of more than 20%, the battery is at the end of its life.
Do not continue using it. Contact the authorized retailer where you purchased it or
Inlite Technology for battery disposal and replacement.
