TIRE WATCH TM FOR MOTORCYCLE
USER MANUAL
Thank you for purchasing this TIRE WATCH TM system. TIRE WATCH will allow you to drive with more confidence and be
alerted in the event of a slow leak or puncture. The setup options for the TIRE WATCH TM system are detailed below.
For first time use, follow the instructions below. You may not set the system values as detailed in section
(C) until the following sensor allocation is completed.
A: FIRST USE OF THE DISPLAY
FIG 9 –MENU 06 : FRONT & REAR TIRE IDENTIFIER (ID) ALLOCATION
The first time the display is powered up, it has to verify the unique ID of the front and rear tire (the unique ID’s are pre-
programmed during manufacture - not allocated to a position - and have to be confirmed now to the display).
Turn ON the display short push on or
If this learning phase fails dashes will be displayed instead pressure values. Then you will have to start again the ID
confirmation process
Switch off the display and wait 8 minutes, motorcycle stopped, before repeating this phase
If the pressure values are not displayed after several trials, please contact your dealer.

Note : Permanent back light function : to activate the permanent back light press and .simultaneously. Do the
same to turn off the permanent back light. The permanent use of the back light uses excessive battery life so its usage is
recommended at night only.

E –ALLOCATE YOUR WHEEL UNIT SENSORS
Process to follow when you change one or two wheel unit sensors OR when the first learning phase has failed
FIG 9 –MENU 06 : ID RECOGNITION
During all the learning process, tires must at least be inflated at 1 bar.

Note : Pressure alert has priority even if temperature alert is active
In case of values inversion during the learning phase, (in general front
pressure is the lowest value), you can invert them.

When the display receives lower pressure information compared to the
programmed thresholds (Pmin), the alert starts:
- during the first 3 minutes led blinks in alternance with bar symbol / arrow
of the faulty tire- then bar and arrow symbol will flash until new tire
inflation (backlight on during 3 minutes to see the alert at night drivings)
To display tire temperature during alert short push on - The display
will return automatically to pressure alert after 10 seconds
A high temperature threshold is programmed at 80°C for front tire and 90°C for
rear tire and cannot be changed.
When the display receives upper pressure information compared to the
programmed thresholds, the alert starts:
- °C symbol / arrow of the faulty tire are flashing until the tire comes to a
lower value than the programmed threshold
To display tire pressure during alert short push on - The display will
return automatically to temperature alert after 10 seconds

G –HOW TO FIX YOUR DISPLAY
FIG 15 –HANDLE BAR FIXING
The pressure information blinks alternately with Lo symbol to inform you
that the sensor must be replaced. Ask your distributor.
Note : In winter conditions do not care about this message below 8°C
(external temperature)
.
Put the display to the
selected place on the
handle bar and fix it with the
screw kit n°12. Then clip the
display and place the CPA
n°8. The tab that allows you
to remove the display is now
blocked.
Battery symbol is blinking to inform you that you have to change the battery of
the display (PANASONIC OR MAXELL CR2450 only)
In case the receiver does not receive the RF frames sent by the sensors, dashes
will be displayed instead of pressure / temperature value. If the problem is
permanent, please contact your distributor.
