Rechargeable Batteries

Rechargeable lead-acid batteries are the same type used in automobiles. As with your car
battery, how you use this battery has a significant impact on its lifespan. With proper use and
treatment, a lead-acid battery can last for years. Here are some recommendations for getting
the longest life from the internal battery.

General
Usage

Fully charge the battery before using the speaker.
Charge the battery completely after each use.

Storage

Repair If the battery fails to charge, contact Alto Professional at altoproaudio.com.

Disposal

For best product longevity, do not store at exceedingly hot (greater than
90 °F / 32 °C) or exceedingly cold (less than 32 °F / 0 °C) temperatures.

It is acceptable to leave your speaker plugged in. This will not overcharge the
battery.

If you leave the battery level low and do not charge it for 6 months, it may
permanently lose capacity.

Bring the unit to a recycling center or dispose of in accordance with local
ordinances.

Important Safety Precautions

Please note: Alto Professional and inMusic are not responsible for the use of its products or the

misuse of this information for any purpose. Alto Professional and inMusic are not responsible
for the misuse of its products caused by avoiding compliance with inspection and maintenance
procedures. Please also refer to the included safety and warranty manual for more information.

Caution: To reduce the risk of electric shock, do not connect Uber LT to a power outlet
while the grille is removed.

Sound Level

Permanent hearing loss may be caused
by exposure to extremely high noise
levels. The U.S. Occupational Safety and
Health Administration (OSHA) has
specified permissible exposures to
certain noise levels. According to OSHA,
exposure to high sound pressure levels
(SPL) in excess of these limits may result
in hearing loss. When using equipment
capable of generating high SPL, use
hearing protection while such equipment
is under operation.

Hours per daySPL (dB) Example
8 90 Small gig
6 92 Train
4 95 Subway train
3 97 High-level desktop monitors
2 100 Classical music concert

1.5 102 Riveting machine
1 105 Machine factory

0.5 110 Airport

0.25 or less 115 Rock concert

player, MP3 player, or other audio source. The Volume control adjusts auxiliary input and Bluetooth
volume.

5. Master Volume Control: This adjusts the loudspeaker's main mix volume, which includes

Instrument/Microphone Inputs, Auxiliary Input, and the audio of a paired Bluetooth device.

6. Line Out: This 1/4" (6.35 mm) TRS output can be connected to a stereo auxiliary input or to a mixer

using a TRS-to-dual-TS splitter cable (not included). The Line Out is post-Master Volume Control.

Operation

Pairing a Bluetooth Device

1. Turn on your Bluetooth device.

2. Turn on Uber LT using the power switch. If you have previously connected to another Bluetooth
device, Uber LT will reconnect.

3. Navigate to your Bluetooth device’s setup screen, find Uber LT and connect.
Note: If your device requires a passcode or PIN, enter 0000.

4. The Bluetooth LED will light up solid when it is "paired."
If your Bluetooth device is not able to connect to Uber LT, press the Bluetooth button on Uber LT to

break previous Bluetooth connections and reset the Bluetooth module.

5. Start playback from your Bluetooth device.

6. To disconnect a connected Bluetooth device and connect to another Bluetooth device, press the

Bluetooth button. Repeat Step 3.
Note: If you experience trouble connecting or playing music, update your device's OS.

Pairing a Bluetooth Device Using NFC

NFC (near-field communication) allows data exchange from devices, such as pairing, by gently bumping
them together. Check in your device’s manual to see if this feature is supported.

To use NFC to pair with Uber LT:

1. In order to use NFC, your device must be turned on and unlocked.

2. Enter your device’s Settings menu and check that NFC is turned On (one-time step).

3. Power on Uber LT.

4. Touch and briefly hold your device to the NFC logo located on Uber LT’s top panel.

5. Follow the pairing instructions that appear on your phone. If a passcode is required, enter “0000”.

6. To unpair, gently bump your device against the NFC logo.

Using the Aux Input

Connect your smartphone, MP3 player, or similar device to the Aux Input. Adjust the output volume on your
source device and then adjust the overall volume using the Aux Input Volume Control on Uber LT.

7

Troubleshooting

If the unit is not charging: Make sure the power cable is properly connected to the power

input and the power outlet.

If the sound is distorted: Try lowering the volume control of your sound source, musical
instrument, or microphone. Also, try to reduce the overall volume of Uber LT using the Master
Volume knob.

If there is too much bass: Try adjusting the tone or EQ control on your sound source to lower
the bass level. This will allow you to play the music louder before clipping (distortion) occurs.

If there is a high-pitched whistling noise when using microphones: This is probably
feedback. Point the microphone away from the speaker.

If you can’t hear the microphone over the music volume: Turn down the music volume
from your source.

If you can't hear your instrument: Check the setting of the Line/Mic switch. If you are using
an instrument with passive pickups, set the switch to the Mic setting.

If you can’t play music from a flash drive: The USB port is only for charging USB devices.

If you cannot connect your audio device to Uber LT via Bluetooth:

• Have your audio device (e.g., smartphone or tablet) and Uber LT as close together as
possible while trying to connect. Make sure both the audio device and Uber LT are
unobstructed by walls, furniture, etc.

• Reset the Bluetooth connection on Uber LT to disconnect Uber LT from any other audio
device and restart the search process. If this does not work right away, power off Uber
LT and then power it back on. See Pairing a Bluetooth Device Using NFC for more
information.

• Reset the Bluetooth connection on your audio device by turning Bluetooth off and back
on. You can find this under the Bluetooth menu in the Settings for your phone or other
audio device.

If this does not work, and you have connected to Uber LT before, find Uber LT in the list
of available or previously connected devices in your audio device's Bluetooth menu, tap
the "gear" or “i” icon located next to it and then select Unpair or Forget. Turn Uber LT
off and back on and try pairing again once it reappears in your available devices list.

Note: If Uber LT has been paired to another audio device recently that is still within
range, you may need to repeat this process with that audio device to fully disconnect.

exposición permisibles a ciertos niveles de
ruido. Según la OSHA, la exposición a
niveles de presión sonora (SPL) elevados
que excedan estos límites puede causar
pérdidas auditivas. Cuando utilice equipos
capaces de generar SPL elevados, use
protecciones auditivas mientras dichos
equipos están en funcionamiento.

Horas diarias SPL (dB) Ejemplo
8 90 Música de bajo volumen
6 92 Tren
4 95 Tren subterráneo
