The Tempus Pro does not need to be turned on to check the battery.
If batteries do not retain their charge state, users should try charging them fully on an external charger. As
batteries become old and over many charge/discharge cycles, users should expect to see a reduction in
their capacity. Such batteries should be replaced at the user’s discretion.
11.1.2 Removing the battery from the Tempus Pro
WARNING
Do not short
-
circuit the terminals of any battery. A short circuit can occur if the
battery terminals come into contact with any metal or other electrically conductive
object. The battery may be irreversibly damaged if it is short-circuited.
WARNING
Ensure the latches on both sides of the battery are fully engaged prior to using the
Tempus - an incorrectly fitted battery could result in the Tempus losing power during
use.
Note
Before removing the battery, you must switch off the Tempus Pro by pressing the power
button.
If necessary, you can force a hard shut-down by pressing and holding the power button for
10 seconds.
Remember that the battery cannot be removed until the lamp on the front panel has gone
out.
The Tempus Pro should not be used without the battery fitted.
To replace the battery:
 First check the replacement battery has sufficient charge by checking its indicator.

 Next, ensure the Tempus is switched off. Then remove the battery by squeezing the two latches
inwards and then pull the battery away.
