The portable oscilloscopes in this range are designed to operate on a power
source delivering 98 to 264 V (ACrms) or in stand-alone mode with a battery.
The instruments are delivered with a mains adapter, an external power supply
(battery charger) and an Ni-MH battery (9.6V, 3.5Ah).

Type: time delay, 2.5 A, 250 V, 5 x 20 mm
The external power supply is equipped with a protection fuse that must only be
replaced with an identical model.
Replacement must only be performed by qualified personnel.
Contact your nearest service centre.

Do not insert any metal objects into this lead.
• Connect the mains lead from the external power supply to the external
