Abrasive particles, such as sand, should not be wiped off
lenses, but instead blown off or brushed away with a soft
brush.
Do not apply excessive pressure when adjusting focus. Keep
away from water and high humidity. Do not submerge.
Protect the device from sudden impacts and excessive
mechanical force.
Store the device in a dry, cool place away from hazardous
acids and other chemicals, away from heaters, open fire
and other sources of high temperatures. Do not use the
device for lengthy periods of time, or leave it unattended
in direct sunlight. Always store the device in a special case.
We recommend keeping the silicate gel packet, included in
the kit.
During long storage, a thin white film may appear on the
rubber armor. You can wipe it clean with a clean napkin.
