DURING USE

SILVA INTELLIGENT LIGHT® AND FLOW LIGHT

SILVA Intelligent Light® optimizes the light pattern by the unique combination of a long reach spot light and a close flood light. With less head movements and a clear view of near as well as far obstacles, you gain the balance and confidence it takes to move fast and perform better. Our ingenious SILVA Flow Light takes the optimization even further by providing seamless tuning of the light pattern for your favourite sport. Simply tilting the light down-wards makes the beams wider to brighten up slower activities. When tilting the headlamp upwards, the light reaches longer to provide perfect vision when you move fast.

SWITCH ON YOUR HEADLAMP

A push button is located on the left side of the headlamp body. This button controls all light modes.

To start the headlamp with Flow Light activated press push button with a short press.
To start the headlamp with Flow Light deactivated press and hold push button for 1 second
To cycle between the different modes use short presses.
To turn the headlamp off press and hold button for 1 second

Switch On Headlamp

DEACTIVATED FLOW LIGHT

Flow Light deactivated means that the Light image will remain unchanged even if the headlamp is tilted up or down. This might be useful when the lamp is mounted on a helmet or a bike handle bar.

TEMPERATURE CONTROL

Note that the headlamp body temperature will increase during use. The headlamp temperature is depending on light mode, ambient air temperature and the airflow (speed). Trail Speed 4R is equipped with a temperature control unit that prevents the headlamp body from overheating by reducing the power to the LEDs. This means that the lower the ambient temperature, the stronger the light output.
Note! Always make sure to disconnect the battery when the headlamp is stored in a closed compartment such as in a bag, pocket or similar.

BATTERY STATUS INDICATION (2.0. AH BATTERY)

When battery is connected to the headlamp and turned ON, current charge status is visible for 30 seconds on the battery pack.
If you want to check battery status during use, the headlamp needs to be turned OFF and then back ON.

LOW BATTERY WARNING

During operation of the headlamp there will be a low battery warning when 10% of the bat-tery energy remains. This is done by flashing both LEDs for 1 second and repeated again after 5 seconds.

RESERVE MODE

During operation, the lamp will go into reserve mode when there is 10% power left of the bat-tery. All LEDs will flash once before the lamp goes into this mode.
Reserve mode can be overridden by pressing the button.
Warning: If you have pressed the button when headlamp is in reserve mode no more low bat-tery warnings will appear before the headlamp turns OFF.
