Instruction Manual

Servicing the TM1
From time to time, depending on the reporting frequency, local cell tower signal strength
and climatic conditions, the three “D” cell batteries will require replacement.
(i) If the TM1 is in a Hazardous location, remove it to a safe location first.
(ii) Then insert the magnetic Keeper.
(iii) Remove the four screws holding the base and the upper cover using a Philips
screwdriver.
(iv) With the top cover removed, observe the location of the batteries and the way
they are held in place.
(v) Cut away any zip ties allowing the batteries to be carefully removed.
OBSERVE the battery polarity. Two on one side have POSITIVE facing UP and
the single battery on the opposite side of the board should have the Negative
facing DOWN.
(vi) Replace the three “D” cells with top quality long life batteries such as
Duracell “Quantum” or Energizer “Ultimate”.
Select ones having at least 5 years shelf life.
Do NOT use rechargeable batteries.
Do NOT use old batteries.
Do NOT mix battery types or old ones with new.
(vii) Make sure polarity is correct and use two zip ties thro holes in PCB provided to
hold the three cells in place. Make sure the ties are clear of other components
when tightened. Cut off any excess zip tie.
(viii) With the two-battery set facing you, carefully refit the top cover with the magnetic
keeper to your left. Screw the 4 screws tightly ensuring proper engagement of
the top and the base.
(ix) Make sure the magnetic keeper is installed correctly for 15 secs before removing
for activation.
DO NOT TAMPER or ATTEMPT ANY REPAIRS YOURSELF.
Always contact your supplier for service, repairs or changing device factory settings.
