There are a number of service operations that you can access on the
SERVICE tab.
Select the SERVICE tab by pressing on the tab at the bottom of the touch screen, or by
pressing the grey Menu (☰) keypad button to the right of the touch
screen.
The Service tab has a more complex structure than the other tabs, consisting of a menu tree
that is four or five layers deep in some places.

Note the following when navigating the SERVICE tab:
At each level of the menu, you can go deeper by pressing one of the options on the
screen, or you can return to the previous level by pressing the grey C (cancel) key on the
keypad, or by pressing the previous part of the menu path displayed at the top of the
screen.
Tap Home to return to the top level menu, or press the grey Menu
keypad button.
Generally, the Service tab will retain the current location within the menu tree if you
switch to another tab and then come back to it.
