Famous Trails FT 700 - User Manual

Our Return Policy
In the rare case that your unit should malfunction,
please call (877) 97-SCOPE for assistance. Rather than go
through the trouble of returning it to the point of purchase,
call Famous Trails Inc. first. We’ll be able to assist you and
correct your problem with minimal inconvenience.
A Quick Start Guide
This is an advanced night vision device. Therefore, never
use it in bright light. If your particular unit requires a battery/
batteries for use, install it/them now. While in dimly lit
surroundings, remove the lens cap and push the energizer button
for 1–2 seconds and release it. The unit will stay illuminated
for a short period of time as the energy slowly dissipates from
the intensifier. Remember that there are two focus rings on all
of our units. One is on the front lens, and the other is located at
the rear ocular (where you put your eye). Remember to handle
your new Famous Trails Inc. night vision device with some
degree of care; it’s a high-end piece of electronics. Keep it away
from water, and always utilize the hand strap/ wrist lanyard to
avoid any accidents.
Enjoy!
