Power Supply
The Portable Programmer is fed by a 6LR61 type 9V DC alkaline battery.
The programmer switches itself off if it has not been used for 30 seconds, and this prevents us
from leaving the programmer on.
The memory of the Portable Programmer is volatile, and hence if we remove the battery or if the
battery runs down it will lose the information stored in it.
The battery is housed on the bottom base of the Portable Programmer. To extract it we must
remove the bottom lid of the Portable Programmer.
The Portable Programmer also indicates us the battery charge level.
In the top left corner of the main screen of the programmer there is an indicator of the charge
of the battery, as shown in the following illustration:
Besides, the Portable Programmer includes a connector to be fed through an external power
supply. Thus, when the Portable Programmer is being fed externally, it does not consume
battery.
This feature is useful to carry out different operations with the Portable Programmer in the
computer. Using only batteries to carry out operations on the door.
The consumption of the Portable Programmer, with the screen light switched off is 20mA either
in a stand-by state or communication state. If we switch on the light of the screen, the
consumption will increase in 10mA.
