Open the battery compartment with the small locking mechanism, press it down and slip
down the door. The door is attached to the front face of the processor module and cannot
be removed.
Remove the TA521 battery from its package and hold it by the small cable. Remove then
the small connector from the socket, do this best by lifting it out with a screwdriver.
Insert the battery connector into the small connector port of the compartment. The con-
nector is keyed to find the correct polarity (red = positive pole = above).
Insert first the cable and then the battery into the compartment, push it until it reaches the
bottom of the compartment.
Arrange the cable in order not to inhibit the door to close.
Pull-up the door and press until the locking mechanism snaps.
In order to prevent data losses or problems, the battery should be replaced after
3 years of utilisation or at least as soon as possible after receiving the "low
battery warning" indication.
Do not use a battery older than 3 years for replacement, do not keep batteries
too long in stock.
To ensure propper operation and to prevent data loss, the battery insertion or
replacement must be always done with the system under power. Without battery
and power supply there is no data buffering possible.
Open the battery compartment with the small locking mechanism, press it down and slip
down the door. The door is attached to the front view of the processor module and cannot
be removed.
Remove the old TA521 battery from the battery compartment by pulling it by the small
cable. Remove then the small connector from the socket, do this best by lifting it out with a
screwdriver.
Follow the previous instructions to insert a new battery.
