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).

Usage Features:

Light Operation: The ON/OFF switch (A) controls the light. A single press turns the light on at 100% brightness. Subsequent presses cycle through 50% and 10% brightness settings, extending the operating duration. Pressing the switch again turns the device off.
Bluetooth Speaker Operation: To use the speaker, activate Bluetooth on your pairing device (e.g., smartphone) and ensure it's in pairing mode. Press the Bluetooth switch (B) on the GWL-20BT. The LED indicator above the Bluetooth switch will light up. Search for "Gardner Bender GWL-20BT" on your device's display and select it. The GWL-20BT will emit two beeps upon successful connection. Music from the paired device can then be played through the speaker. Volume control is managed via the paired device. To disconnect, deactivate "Gardner Bender GWL-20BT" on the paired device or switch off the Bluetooth function via the Bluetooth switch on the GWL-20BT.
Power Bank Function: Connect a USB charging cable from the target device to the USB charging port (D) located under the transparent cover cap on the back of the device. This allows for charging of smartphones and other USB-powered devices with a current of up to 2000mA.
