Infinite brightness adjustment varies
from 0.1 to 750 lumens and is
manually adjusted by rotation of the
Smart Selector Ring. Subsequently,
runtimes will vary anywhere from 105
minutes to 450 hours depending on
chosen level of output.

Switching ON/OFF

To switch ON: Press the button on the tailcap until a “click” is heard.
To switch OFF: Press the button on the tailcap a second time until a
“click” is heard.

Momentary Illumination

Momentary illumination can be achieved by switching the flashlight off
and then half pressing and holding the tail switch. Release switch to turn
the light off.

Adjusting Output

With the light turned on, slowly rotate the Smart Selector Ring (adjacent
to the bezel) in a counter-clockwise direction to cycle through the
following brightness levels: beacon -> SOS -> police warning signal ->
blue mode -> red mode -> lower mode -> infinite brightness modes ->
turbo mode -> strobe mode. These modes may be cycled through in
reverse by rotating the Smart Selector Ring in a clockwise direction.

Note: When using the SRT5 in infinite brightness mode, runtime will
increase when lower levels of output are selected. On its lowest setting,
the SRT5 will run continuously for up to 450 hours and on its highest
setting continuously for up to one hour and 45 minutes.

NB:

For user safety and to prevent overheating / failure, the SRT5 will
automatically switch to high mode after three minutes of use in Turbo
mode. Slowly rotate the Smart Selector Ring or press the tail switch again
to reactivate turbo mode when needed.

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by a
thin coating of silicon-based lubricant.
