1.1 Prior to use
Before use, T4 should always be checked for any signs of physical damage.
T4 uses a Lithium Ion (Li-ion) battery pack and should arrive with sufcient charge to be used
straight out the box. However, if this is the rst time of use, the battery will require charging to attain
the full operating time (see Charging & battery indications on page 13).
For battery run times, see the table on page 46.
