5 Getting started
The Mojo 2 manual is divided into two key sections: basic operation and advanced operation. Basic
operation (6.0) covers everything needed to get started and enjoy using Mojo 2. More advanced menu
options are explained in 7.0.
6 Basic operation
6.1 Connecting to power
Mojo 2 can be used while constantly connected to power, or on the go, thanks to powerful, rechargeable
batteries. A charger capable of outputting a minimum of 2 A (amps) is recommended for Mojo 2; please
check your charger specifications. Connect the supplied cable to Mojo 2’s Micro-USB charging input (see
D, above) and then to a 5 V power source to begin charging.

6.2 Battery status indicator
With Mojo 2 connected to power, the charge status LED (see F, above) will pulse and show battery
charge status using colour (see chart below); the charge status is also displayed when operating on
battery power alone.
NOTE A blue charge status LED indicates the maximum battery capacity range has been reached.
If Mojo 2 is left constantly on charge, it will enter intelligent desktop mode to protect the battery from
overcharging. This will be indicated by a purple battery status light.
Battery status Battery charge
75 % to 100 %
40 % to 75 %
10 % to 40 %
2 % to 10 %
Flashing
0 to 2 %
Intelligent desktop mode
6.3 Depleted battery
Following full depletion of the batteries, the charge status LED will flash red for ten seconds. If coupled with the
device shutting down, a recharge is required.
If following a period of inactivity the device fails to power-on (suggesting a severely depleted battery) then the
device needs to be recharged overnight, with the unit switched o.

6.4 Connectivity: inputs
Connect compatible digital devices, including laptops, smartphones, tablets and more to Mojo 2’s
corresponding digital inputs. These include: 3.5 mm coaxial (single coax: tip: signal, sleeve: ground. Dual data
coax [for use with Hugo M-Scaler]: tip: signal 1, ring: signal 2 sleeve: ground, USB-C, Micro-USB and optical
inputs. If all four inputs are connected simultaneously, Mojo 2 will auto-select the correct input when music is
played to the device. Mojo 2 will prioritise specific inputs if all four are connected simultaneously. USB has
priority followed by coaxial and then optical. It is only possible to connect one USB at a time (Micro-USB takes
priority over USB-C).

6.5 Connectivity: outputs
Connect up to two pairs of (3.5 mm mini-jack) headphones to Mojo 2, simultaneously. The device’s volume
control (see section 6.8) will adjust both headphone outputs together (there is no independent volume control
for each headphone).
6.6 Powering on/o
Press and hold the power button (see section 4) until it becomes illuminated, then release. Mojo 2 will perform
a number of start-up checks indicated by the power button cycling through a range of colours. During this
process, the menu button will also automatically cycle through its designated colours; any previously saved
menu settings will be displayed using colour on the ‘+’ and ‘- ‘ buttons (see section 7 for menu options and a
full guide to colours). Mojo 2 is ready to use once the colours have stopped cycling. To power down, press and
hold the power button until the lights are extinguished.

TIP Mojo 2 will auto-shutdown after 10 minutes without an input signal.
6.7 Brightness adjustment
Mojo 2 oers two levels of button brightness: normal and low. Normal is activated as standard, however, to
alternate between low and normal brightness modes, press menu once (menu button will show blue) then
‘-’ repeatedly to move between normal and low modes; any lit buttons will increase or decrease in
brightness accordingly. Once chosen, the selection will be remembered and Mojo 2 will automatically exit
the menu settings in 10 seconds. Alternatively, press and hold menu to exit the menu immediately.
6.8 Volume adjustment
Mojo 2 benefits from two main volume ‘ranges’: low and high, as indicated by the colour of the menu
button: unlit (low); white (high). As the volume is changed, Mojo 2 moves automatically into the respective
volume ranges; the menu button colour changes accordingly.
With chosen devices and headphones now connected (but not on/in ear), and Mojo 2 powered on, the
volume can be reduced to zero using the volume down ‘-‘ controls until both volume buttons and menu
button are unlit. From unlit, the volume can be slowly increased by pressing the volume up ‘+’ button. Both
buttons slowly change colour with changing volume level.
Always set the volume level to zero before commencing initial playback and take precautions
when using Mojo 2 in high volume mode to protect from hearing damage.
