WARNING
Remove the batteries before you store the riflescopes for extended
periods (2 weeks or more).
WARNING
Do not carry batteries in pockets containing metal objects such as
coins, keys, etc. Metal objects can cause the batteries to short cir-
cuit and become very hot. In the case of lithium batteries, a short
circuit could cause them to explode.
WARNING
Observe battery manufacturer's guidelines for safe handling and
proper disposal of batteries.
EQUIPMENT LIMITATIONS
• The TTWS Series detector spectral band (7 to 14 mkm) pro-
vides a better penetration through smoke, smog, dust, water
vapor etc.
• Infrared radiation does not travel through glass and therefore
the scope does not sense objects if they are behind a glass
window.
