1.3 ROX 5.0 functions
The ROX 5.0 is a versatile bike computer that can measure distance, speed,
cadence, and heart rate.
All current values – current speed, current heart rate, current cadence, and
current lap – easily viewed on the large display.
The ROX 5.0 has classic bike computer features such as 2 programmable
wheel sizes (automatically detected with the STS speed transmitter), an
automatic start/stop function, and several other functional view options.
1.3.1 PC interface
The ROX 5.0 can be connected to a PC or Mac. The optional docking station
enables you to transmit data between your PC and the ROX 5.0.
You can also set up the ROX 5.0 on the PC and then transmit the settings to
the bike computer.

Initial use
2.7 Initial use
To preserve battery life, the ROX 5.0 comes in ‘deep sleep mode’. Simultaneously
press and hold the MODE 1 + SET buttons for five seconds to awaken the
ROX 5.0 from deep sleep mode.
The ROX 5.0 jumps to setting mode (Section 4, pg 16).
2.8 Synchronizing the transmitters
To synchronize the transmitters, the ROX 5.0 must be clicked into the handlebar
or wristband bracket.
The zeros of the speed, cadence, and heart rate values flash while the respective
transmitters are being synchronized.
Once synchronization is complete, the respective values appear on the ROX 5.0’s
display.
2.8.1 Synchronizing the speed
There are two options for synchronizing the speed:
−− Start cycling – the receiver usually synchronizes with the transmitter after
five wheel rotations.
−− Spin the front wheel until the speed information appears on the display.
2.8.2 Synchronizing the cadence
There are two options for synchronizing the cadence:
−− Start cycling – the receiver usually synchronizes with the transmitter after
five pedal rotations.
−− Turn the pedals until the current cadence appears on the display.
2.8.3 Synchronizing the chest belt
Moisten the electrodes on the chest belt and put it on.
Move within 100 cm (approx 36 inches) of the ROX 5.0 or get onto your bike.
The ROX 5.0 usually synchronizes with the chest belt in less than 10 seconds.
The current heart rate then appears on the display.

Frequently asked questions (FAQ)
‘TOO MANY SIGNALS’ displayed
−− Please increase the distance from other transmitters and press any button.
7.3 Frequently asked questions (FAQ)
Can I change the batteries myself?
All ROX 5.0 components have a battery compartment so that the owner can
change the batteries. When doing so, please ensure that the sealing ring is
always correctly positioned before you close the battery compartment.
Can another person with a different bike computer/heart rate monitor cause
interference?
The digital transmission system is coded. This almost entirely prevents any
interference between two different bicycle computers. When synchronizing the
receiver with the transmitter, ensure that you are not in the vicinity of any other
SIGMA ROX devices.
How long will the batteries in the transmitter and receiver last?
The battery life depends on how much the device is used and whether the
backlight is used.
In general, the ROX 5.0 and all three transmitters are designed so that the
battery lasts at least a year (based on one hour of use each day).
Is the STS transmission system compatible with other transmission systems
(e.g. Bluetooth, ANT+, DTS etc.)?
No, the various transmission systems are not compatible with one another.
