Low Battery Charge Level Indication
If battery charge is getting low, then Nora3 will automatically blink the main LEDs to indicate this, a few
seconds after a new setting has been selected. Following this brief warning, operation will continue as normal
with reducing light output as battery is now quite low, and green indicator LED will blink (not visible with
helmet on) at 1 second intervals. Nora3 has been configured to deliver a low light from fundamentally flat
battery packs for some time, therefore minimizing the risk of being left without light. However, at this point you
might consider using a lower light setting, or changing battery.
Ultimately, the Nora3 will restrict illumination to moon mode, and li-ion batteries will shut down at a set low
voltage level (typically around 2.7v) to prevent damage. In event of battery protection circuitry failure, Nora3
incorporates an additional layer of protection to ensure that batteries will not be over discharged.
Thermal Management
While operating, Nora3 continually monitors lamp temperature. If lamp gets too hot then main LEDs will blink
and the power will be reduced to a allow lamp to cool. White smd indicator LED will blink (not visible with
helmet on) at 1 second intervals while under thermal regulation. Lamp function is not locked, and simply
changing light setting will restore full operation, though be aware that unless a lower light setting is used for a
few minutes in order to provide time for the lamp to cool, then thermal management may quickly reactivate. In
reality, you are probably only likely to see this if running continuously for extended periods, using high settings
and in warm environments; as the Nora3 provides a very effective heat sink.
Nora3 Programming
Nora3 can be easily configured to individual requirements, using infrared remote control. To program lamp,
point the controller at Nora3 front window. The receiver is within the lamp housing.
Programming is possible when Nora3 is initially connected to a battery and with lamp switched
off
. If
programming function is required, it is important to press the switch before connecting battery (or alternatively
disconnect the battery from a lamp
on
setting and reconnect). If no programming activity has occurred for
5
minutes
, the programming link is disabled, in order to protect your settings, until the battery is next
reconnected. While the programming link is active the green indicator LED will blink every 8 seconds.
Number of Light Settings
Nora3 has
4 factory default light settings
. This can be modified from
1 to 9 settings
depending on your
requirement. To select the desired number of light settings enter # followed by the number of settings required
and OK to confirm,
<#(number of settings 1-9)OK>
.
If the number of light settings selected is less than the current number, then any settings no longer required
will be taken from the end of the current sequence. For example, if lamp is currently configured with 6 settings,
and 3 settings are selected, settings 4-6 will be removed.
Any additional settings will be added to the end of the current sequence, immediately before the off position.
These will be set at
low flood,
unless they have previously been programmed, in which case they will be set
at the last stored configuration.
Configuring a Light Setting
Nora3 allows the light level of each setting to be modified to individual requirement. To modify a light setting,
enter * followed by the number of the specific setting you wish to modify
<*(setting number 1-9)>
. This will
only respond to the number of light settings currently specified (as described above). For example, if the lamp
currently has 4 light settings, then only controller buttons 1-4 will respond.
When a valid light setting is selected, use the arrow buttons on the remote to select the desired level of light
for each LED. The level of the
spot
LED is set using the
<up>
and
<down>
arrows, and the level of the
flood
LED is set using the
<left>
and
<right>
arrows. Either of the LEDs can be set as off, but not both. When you
have selected the desired light levels of spot and flood LEDs, then enter
<OK>
to confirm. This procedure can
be repeated for any specified light setting.
