Operating Features
The Forward FN455S device is designed for long-term use. Please follow
these guidelines to ensure long life and maximum performance:
Before using the attachment make sure you mount it according to the
instructions in the
Installing Digital Module on the Optical Device
and Installing Pulsar 5x30 Monocular on to the Digital Module
sections.
Power off the device after use.
Do not repair or dismantle an attachment under guarantee by yourself!
The device can be used over a wide range of temperatures. If the device
has been operated in the cold and brought into a warm room, do not
remove it from its carrying case for at least 2-3 hours; this will prevent
condensation forming on the external optical elements.
Inspect and maintain the device regularly to ensure trouble-free
operation and to avert and eliminate the cases of premature wear and
tear and failure of components.
