OPERATING INSTRUCTIONS
1. Adjusting Mounting Bracket/Stand
The tilting angle of the light can be adjusted as necessary by means of the folding bracket. To do so, loosen the
winged screws and re-tighten them after adjustment. The light can be mounted on a tripod (not included in package).
2. Switching the Light ON/OFF (A)
Use the ON/OFF switch (A) to switch the light on. The light is now lit with 100% brightness. Press the switch twice to
set the brightness to 50% and then 10%. This way, the lighting duration is respectively extended. To switch off the
device, press the ON/OFF switch (A) again.
3. Bluetooth Speaker (B)
To use the speaker via Bluetooth, reference Figure 1 & 2 and make sure the Bluetooth function on your pairing device
is turned on and in pairing mode. Press the Bluetooth switch labeled (B) in Figure 2 (designated by the Bluetooth
symbol on the back of the device). When the LED indicator light over the Bluetooth switch (B) lights up, look for
"Gardner Bender GWL-20BT" on the display of your pairing device. Select "Gardner Bender GWL-20BT" on your
pairing device and GWL-20BT will produce 2 beeps once successfully connected.
Any music on the paired device can now be played via the speaker on the GWL-20BT. The volume is
controlled from the paired device. To terminate the connection, deactivate
"Gardner Bender GWL-20BT"
on the paired device. The connection can also be terminated by switching off the Blue tooth function via
the Bluetooth switch on the GWL-20BT.
4. Battery Status Indicator (C) - Figures 1 & 2
Indicates the current battery charge when the light is switched on. If all 4 LEDs are lit, the battery is fully charged.
If the battery is almost empty, the LED light flashes 5 times and the battery status indicator flashes continuously.
Afterwards, the light remains on for about 10 minutes with reduced brightness before it is switches off by the deep
discharge protection function. This ensures sufficient time to change the battery, plug in device or complete the task
the light is being used for (without acoustic signal).
