1. IMPORTANT SAFETY NOTES
Please read the following important safety information before installing
the system.
1.1 System safety
TyrePal TA22X mon tors up to 22 tyres, and prov des an mmed ate warn ng f the
pressure or temperature of any tyre dev ates from pre-set levels. It s ntended to
help you ma nta n your tyre pressures at the opt mum levels for safety, fuel
economy, tyre l fe and env ronmental mpact.
It s your respons b l ty to ensure that t s su table for your part cular veh cle and
that t s work ng correctly and properly ma nta ned. Check the sensors and valve
stems regularly, as some road salts can cause corros on.
The system does not replace the need to carry out regular checks on the
condition and wear of your tyres.
1.2 Batter es and small parts
Keep the small parts and espec ally the batter es out of the reach of ch ldren. If a
battery s swallowed, consult a doctor. Do not hold a battery w th metall c tweezers.
It may cause a short c rcu t. Do not recharge, d sassemble or d spose of batter es n
a f re. Batter es can explode f m streated.
1.3 Use of tyre sealant
Sensors should not be f tted to tyres that have been treated w th nternal tyre
sealant. The sealant may damage the sensor or mpa r ts act on.
1.4 Before nstallat on
Before nstall ng the system, ensure that t s su table for your veh cle.
• Check that the operat ng pressure of your tyres s w th n the range of the
system. .e. 0 - 10 bar (0-145ps ).
• Check that sensor valve caps w ll rema n w th n the outs de prof le of the
tyres when f tted.
• Check that tyre valve stems are n good cond t on before f tt ng the sensors.
• Do not use w th alum n um valve stems.
• Select a locat on for the mon tor un t so that t s v s ble to the dr ver
w thout obstruct ng v s b l ty.

2. PLANNING THE SETUP
Please read this section carefully it will save you time!
You must carry out these steps n the correct order.
1. Charge the mon tor battery and nsert sensor batter es
2. Dec de wh ch tyre pos t ons w ll be mon tored
3. Set the target pressures for each pos t on to be mon tored
4. Reg ster the sensors to each pos t on that s to be mon tored
3. CHARGE THE MONITOR BATTERY
The mon tor s powered from an nternal
rechargeable battery that may need to be charged
before f rst use. It should only be charged using
the supplied adapter wh ch prov des the correct
voltage (5V) when plugged nto the veh cle supply.
Using an incorrect adapter or wiring directly
to the vehicle without the adapter is
dangerous, could cause a fire or explosion and
will permanently damage the monitor. Such
damage is not covered by the warranty.
The mon tor takes s x hours to fully charge the
battery, but t s not harmed by part al charg ng and
does not have to be fully d scharged before
recharg ng. A full charge w ll last for up to 30 days.
If the power s low, a battery warn ng con w ll appear.
Note: If the power s sw tched off w th the system plugged nto
the charger, current may be drawn from the battery nstead of
charg ng t, so don’t leave t connected to the charger when not
dr v ng.

5
4. INSERT SENSOR BATTERIES
Each sensor requ res one l th um CR1632 battery. The polarity of the battery is
critical. Incorrect polarity can damage the sensor. The battery lasts about
one year and a warn ng appears when the battery s low. Make sure the battery
goes ns de the metal cage, not on top of t.
5. DECIDE WHICH TYRE POSITIONS WILL BE MONITORED
There are 22 poss ble tyre pos t ons as shown below. Unused pos t ons w ll not be
mon tored or d splayed, so we recommend that you mark your own tyre pos t ons on
the blank layout below.
Unscrew the cover Insert the battery w th +

Replace the cover and
t ghten f rmly by hand
Tw n axle tra ler 6-wheel tw n rear 6-wheel tag axle
Your pos t ons S ngle axle tra ler Car and tra ler

6. SET TARGET PRESSURES AND UNITS
The target pressure s the requ red normal cold operat ng pressure for each tyre as
recommended by the manufacturer. It s usually pr nted n the veh cle manual and
on a label n the dr ver’s door frame. It s not the same as the max mum pressure
embossed on the tyre wall.
The system automat cally sets a ser es of alert levels commenc ng at 15% below the
target pressure, so f a target pressure s 100ps , you w ll be alerted when the
pressure of that tyre s down to 85ps . Note that th s sett ng only affects the h gh
and low pressure alerts. A blow-out or rap d a r loss w ll always tr gger an alert.
6.1 Enter sett ngs mode
Press and hold the centre button for about f ve seconds. The
front left tyre pos t on con flashes and the d splay shows the
default target pressure and the default un ts.
6.2 Change un ts
To change un ts, press the centre button 22 t mes to scroll
through all the tyre pos t ons unt l the pressure con n the
top left of the screen flashes. Press left or r ght buttons to
select the un ts you requ re.
Press the centre button to store the select on and move on to
temperature.
Press left or r ght to select the requ red temperature un ts and then press the centre
button to store the select on and move back to the f rst tyre pos t on.
6.3 Set tyre pressures
Press left or r ght buttons to adjust the sett ng for the current (flash ng) tyre
pos t on. A s ngle press changes by one step, hold ng t down g ves a rap d change.
Press the centre button to store the sett ng and move on to the next pos t on.
You must set the pressures for all the tyre pos t ons you w ll be mon tor ng, but other
pos t ons can be left at the factory default.

7
6.4 Ex t sett ngs mode
You must ex t sett ngs mode before proceed ng. Press and hold the centre button for
about f ve seconds.
7. REGISTER THE SENSORS
Reg ster sensors to the pos t ons you have dec ded n sect on 5 that you want to
mon tor. On complet on, other pos t ons w ll not be mon tored or d splayed. Sensors
are reg stered by s mply screw ng them onto the tyre valve n place of the normal
dust cap.
7.1 Enter reg strat on mode
Press and hold the left and r ght buttons for about f ve
seconds. The red l ght comes on and the f rst tyre pos t on
con flashes.
7.2 Reg ster sensors
Take the mon tor w th you to the wheel correspond ng to
the flash ng con. Remove the tyre valve dust cap and
screw a sensor onto the valve n ts place. After a few
seconds, the l ght turns green and the tyre pressure s
d splayed. The sensor s now reg stered to th s tyre
pos t on. If reg strat on s not ach eved w th n 30 seconds,
remove the sensor, wa t ten seconds and re-mount t.
The pack ncludes opt onal ant -theft r ngs. We suggest that you complete the
reg strat on process and test the nstallat on before lock ng the sensors n pos t on.
Press the r ght or left button to move onto the next tyre pos t on and repeat the
process unt l you have reg stered sensors to all of the requ red pos t ons.
7.3 Ex t reg strat on mode
Press and hold the left and r ght buttons for about f ve seconds unt l the l ght goes
out. The screen reverts to the Standby d splay.
7.4 Changes after reg strat on s complete
If pressure sett ngs are changed after the sensors have been reg stered, the mon tor
stores the sett ngs, but they do not come nto effect unt l t has been operat ng for
about 20 m nutes.

8
If further sensors are added later, they must be reg stered to allow the target
pressures to be set. In th s case t may be qu cker to reset the ent re system by
de-reg ster ng all the sensors and start ng aga n.
8. TESTING THE SETUP
To test the system, pos t on the mon tor n the dr ver’s cab and unscrew the furthest
sensor. The system should produce an alert for that tyre pos t on, w th the red l ght
flash ng and the ‘leak ng’ con show ng.
T ghten the sensor and the alert should stop.
If the alert s not g ven, the sensor may be out of range. The sensors have a
transm ss on range of about 20 metres n open a r, but n pract ce, screen ng by the
veh cle chass s and bodywork reduce the work ng d stance to about 8 to 10 metres.
Th s can be ncreased by us ng the opt onal s gnal booster.
9. FITTING SENSORS AND ANTI-THEFT RINGS
Sl de the ant -theft r ng onto the valve w th the bars
po nt ng outwards. Screw on the sensor n place of
the or g nal dust cap, but do not over-t ghten.
Adjust the pos t on of the ant -theft r ng so that the
bars engage w th the slots n the sensor and lock t
nto place w th one or more of the lock ng screws
prov ded. Do not over-t ghten or t may damage the
valve stem.
When all the tyre sensors are f tted, check that there
are no leaks by brush ng a l ttle detergent and water
on the valve stems. If bubbles appear, slacken the
lock ng key and ref t the sensor.
9.1 Corros on
Corros on occurs mostly where d fferent metals are n contact n the presence of an
electrolyte l ke salty water. TyrePal sensors have a brass thread and th s presents
l ttle danger of corros on on normal brass tyre valves. The lock ng r ngs are made of
alum n um to m n m se we ght, so these are anod sed for protect on. Wh le the
anod s ng s ntact, there s l ttle r sk of corros on, but f the anod zed surface s

9
damaged, contact between the alum n um and the brass of the sensor or the tyre
valve w ll create a corros on r sk, espec ally dur ng the w nter when roads are salted.
9.2 Ant -corros on precaut ons
1. Put a small amount of WD40 or s l cone grease on the lock ng r ng and on
the threads of the valve stem. Th s f lm separates the d fferent metals.
2. Remove the sensors once a month dur ng w nter to prevent bond ng.
3. Remove the sensors f the veh cle s to be unused for several months.
4. Do not use the lock ng r ngs f the veh cle s be ng used n extremely salty
cond t ons, such as a boat tra ler where the wheels may be mmersed n the
sea.
10. WHEEL BALANCING
The we ght of the sensors s w th n the tolerance generally ach eved for wheel
balanc ng, so there s usually no need for the wheels to be rebalanced after nstall ng
the system. Some veh cles are more sens t ve to wheel balance than others, so f
v brat on s felt when dr v ng at speed after f tt ng the system, the wheels must be
rebalanced.
11. CONNECTING AND DISCONNECTING A TRAILER
If you have sensors on both a tow ng veh cle and a tra ler such as a caravan or a
towed car, when you no longer have the tra ler attached, the system w ll recogn se
th s and w ll show noS (no s gnal) on the d splay. It can take some t me before th s
appears and dur ng th s per od the pressures shown for the tra ler are those wh ch
were detected before the tow ng veh cle went out of range of the tra ler. When the
system does f nally show noS, there w ll be a s ngle beep and the low sensor battery
con may be shown.
When the tow ng veh cle returns w th n range of the tra ler, no act on s necessary,
and t w ll take about 20 m nutes for the mon tor to d splay the correct pressures of
the tra ler. However, f you beg n to tow dur ng th s per os, and a problem ar ses,
then the system w ll detect and warn you w th n s x seconds as normal.
If the mon tor s show ng noS because the mon tor s out of range of the tra ler, the
sensor low battery warn ng can be gnored.

10
12. WARNINGS AND ALARMS
The system checks the tyre pressures and temperatures every s x seconds and an
alert s g ven n the event of an abnormal ty, whether the veh cle s mov ng or
stat onary. The level of alert depends on the sever ty of the abnormal ty. In each
case, the appropr ate tyre con flashes.
12.1 Blow-out
A tyre loses more than 3 ps n less than 2 m nutes:
Constant beep-beep
Wh te LCD screen flashes
Red LED flashes
Tyre pos t on con flashes

Temperature con appears
To turn off the alert, press the r ght or left button.
If tyre temperature exceeds 85˚C, the nd cat on s s m lar except
that beep-beep s cont nuous.
13. CHECKING TYRE PRESSURES
The TyrePal TA22X constantly mon tors all tyre pos t ons that have been
programmed. If you w sh to check each tyre pressure and temperature, press e ther
the r ght or left button from "Stand By" mode. The tyre pos t on w ll be d splayed
along w th ts pressure. Press aga n and that tyre's temperature appears. Press aga n
to move on to the next tyre pos t on that has been programmed.
Note that the pressure and temperature data d splayed are not nstantaneous, but
are values stored n the mon tor. The system checks pressures and temperatures
every s x seconds and g ves an mmed ate warn ng when requ red, but to save
battery power, t only updates the full data every few m nutes. To force an update,
unscrew the sensor to g ve a leak ng alert and t ghten t aga n to stop the alert and
transm t new data.
If a tyre pos t on has been programmed but a transm tter s m ss ng, out of range or
malfunct on ng, the d splay w ll show "noS" (no s gnal).

14. TURNING ON AND OFF
There’s usually no need to turn the system on or off as t w ll automat cally shut
down nto a sleep mode after about ten m nutes of no act v ty to save power. Any
v brat on l ke open ng the car door w ll wake t up aga n.
If you do want to turn t off manually, for example n an RV overn ght, press and
hold the centre button for 8 seconds. Note that t enters the Sett ngs mode after f ve
seconds. Cont nue to hold the centre button down for a further three seconds to
turn the system off.
If t doesn’t turn off after 8 seconds, you are probably n sett ng mode or reg strat on
mode. Hold ng the centre button w ll have ex ted sett ng mode, so you can now
press and hold the centre button for 8 seconds aga n to turn t off.
If the system s show ng a cont nuous red or green l ght, t s n reg strat on mode.
Ex t th s mode by hold ng down the left and r ght buttons together unt l t beeps. The
system can then be turned off as above.
To sw tch t on aga n, press and release the centre button.
15. RESETTING THE MONITOR
To reset the mon tor, you have to de-reg ster all the sensors. Th s may be useful f
you want to extend the system w th add t onal sensors or to start aga n w th a clean
set-up.
♦ Ensure you have a clean start by sw tch ng off the mon tor and then press
the centre button to start t aga n.
♦ Hold down the 2 outs de buttons together unt l the mon tor beeps and
enters reg strat on mode.
♦ The left front wheel symbol w ll flash and the l ght w ll be e ther red or
green. If t s green, that sensor s reg stered. Hold down the centre button
(5 seconds) unt l the system beeps and the l ght turns to red. The sensor s
now de-reg stered.
♦ If the l ght s already red press the r ght button to go on to the next wheel
symbol.
♦ Repeat for each wheel unt l all green l ghts are turned to red, nd cat ng
that all sensors are de-reg stered.

13
♦ Ex t reg strat on mode by hold ng down the 2 outs de buttons together unt l
the system beeps and the l ght goes out.
The mon tor s now reset w th no sensors reg stered.
16. SIGNAL BOOSTER
The sensors have a transm ss on range of about 20 metres n open a r, but n
pract ce, screen ng by the veh cle chass s and bodywork reduce the work ng d stance
to about 7.5 metres. Th s may be further reduced by electr cal nterference, extreme
cold or low batter es.
A s gnal booster s ava lable as an opt on to boost these s gnals. The booster s
powered by the veh cle’s electr cal system and should be connected to a 12 to 30V
supply. It then s mply has to be pos t oned where t can p ck up s gnals from the
sensors and no further programm ng s necessary.
17. TROUBLESHOOTING
If you exper ence d ff cult es w th the system, please check the follow ng.
17.1 Blank d splay
♦ The system may be turned off or n sleep mode – press the centre button.
♦ Internal battery may be flat - recharge the battery. Please note that f the
mon tor has been left connected to a power socket wh le the eng ne s
turned off, the battery may have d scharged through the veh cle system.
17.2 D ff culty n reg ster ng
♦ If a sensor does not reg ster w th n 30 seconds, remove the sensor, wa t
ten seconds and try aga n.
♦ If necessary try a d fferent sensor on the tyre.
♦ If no sensor can be reg stered on a part cular tyre, check the valve core
(actuator). Damaged or bent valve cores, or cores that are too t ght n the
valve may prevent the sensor from depress ng the valve.
♦ If there are problems on tyres where valve extenders are used, test the
sensor on a valve w thout an extender.
If a sensor cannot be reg stered n any pos t on, check that the battery s correctly
nstalled and, f necessary, swap the battery for one that s known to be work ng.

14
17.3 No s gnal - noS
If the s gnal from a sensor cannot be read after t has been successfully reg stered,
the d splay for that tyre pos t on w ll read noS. Th s may be because:
♦ D stance from mon tor s too far. Max mum s normally 7.5 metres - use a
booster. If the mon tor s show ng noS because t s out of range of the
sensors, the low battery warn ng can be gnored.
♦ S gnal obstructed by veh cle – use a booster or repos t on the booster.
♦ Rad o nterference from veh cle or surround ng area.
♦ Low sensor battery - replace the battery.
The system carr es out a full commun cat ons check every few m nutes.
17.4 Incorrect pressure alerts
The system automat cally sets a ser es of alert levels commenc ng at 15% below and
20% above the target pressure. If a h gh or low pressure alert occurs ns de th s
range, the target pressure has probably not been correctly set for that wheel
pos t on.
Note that the target levels are the values stored when the sensors are reg stered. If
changes are made to target pressures after reg strat on, the sett ngs are stored but
not effect ve unt l the system has been operat ng for about 20 m nutes.
17.5 False leak alert on stopp ng
In extreme cond t ons t s poss ble to get a false leak alert on stopp ng f the veh cle
s overloaded or has been dr ven very hard. On stopp ng, the tyre cools qu ckly,
lead ng to pressure reduct on that s nterpreted as a leak. H gh mo sture content n
the a r n the tyre can make th s more l kely.
17.6 D splayed pressure d sagrees w th a pressure gauge
The sensors are accurately cal brated w th n trogen and are accurate to ±4ps . Many
tyre pressure gauges are not very accurate and read ngs may vary w th mo sture n
the a r. Note that the pressure and temperature data d splayed are not
nstantaneous, but are values stored n the mon tor and updated every few m nutes.
If n any doubt, have your tyres checked by a spec al st.

15
18. MANAGING TYRE PRESSURES
18.1 Effects of ncorrect pressure
Incorrectly nflated tyres reduce the contact area w th the road, lead ng to:
♦ less gr p
♦ ncreased brak ng d stances
♦ poor corner ng
♦ uneven tyre wear
If tyres are under- nflated, they have greater roll ng res stance, so they waste fuel
and wear faster.
Dr v ng on tyres below a cr t cal nflat on pressure can cause a blow-out, and can
damage wheel r ms because the tyres no longer support the veh cle.
18.2 What s the correct pressure?
The recommended cold nflat on pressures are g ven n the veh cle handbook and
often also on a label n the door frame. There may be d fferent pressures for front
and rear tyres, and h gher pressures may be recommended when the veh cle s fully
loaded. These recommended pressures are des gned to g ve the best balance
between comfort, road-hold ng and fuel economy for a g ven veh cle.
The s de-wall of the tyre s embossed w th the max mum pressure rat ng for the tyre.
Th s s NOT the recommended serv ce pressure.
18.3 Effect of temperature
Recommended tyre pressures are normally spec f ed for cold tyres, but the tyres
warm up when dr v ng, and the pressure ncreases by about 10% n normal serv ce.
Tyres should be nflated to the recommended level at normal amb ent temperature,
before they are heated by dr v ng. In w nter, tyre pressures fall due to lower
temperatures and add t onal a r s requ red to br ng them to the manufacturer’s
recommended level.
Cond t ons that m ght lead to a h gh temperature alarm are:
♦ excess ve flex ng of tyre wall (potent al blowout)
♦ brakes or bear ng b nd ng
