using the unit.
Reading Table
Unlock the table and place the material you want to read

transport, the bearing carriers in the table slides may
have moved, tending to restrict the extent of the
movement – this is normal. To correct this, extend the
table in all directions to its full extent, applying sufficient
force to re-align the bearing carriers.
The brakes on the table can be used to restrict the table’s

column of numbers easily. Locking both brakes facilitates
writing under the unit.
Power button
Press the power button to turn on the unit. Pressing the
power button again (after the start-up screen has cleared)
