Step Action
1 If a direct key module or control panel interface is connected to the
TP37, remove it (see section 17.1 or 17.2) in order to gain access to
the cover of the battery compartment.
Switch off the voltage supply before removing the DKM or CPI.
After removing the direct key module or the control panel inter-
face, switch on the voltage supply before removing the battery.
2 Remove the grey, plastic cover of the battery compartment at the
rear of the Touch Panel.
3 Remove the battery lead connector from the two–pin plug connec-
tor on the TP.
4 Remove the dead battery from the holder and insert the new one.
The snap–in plastic holder secures the battery in the battery
compartment.
5 Insert the battery lead connector back into the plug connector. The
connector is coded and thus protected against polarity reversal.
6 Stow the lead in the battery compartment and close the battery
compartment.
