Caution
!
Only the MT4080 standard accessory AC to DC adapter
can be used with MT4080. Other battery eliminator or charger
may result in damage to MT4080.
The MT4080 works on external AC power or internal batteries.
To power the MT4080 with AC source, make sure that the
MT4080 is off, then plug one end of the AC to DC adapter into the
DC jack on the right side of the instrument and the other end into
an AC outlet.
There is a small slide switch inside the battery compartment
called Battery Select Switch. If the Ni-Mh or Ni-Cd rechargeable
batteries are installed in MT4080, set the Battery Select Switch to
"Ni-Mh" position. The Ni-Mh or Ni-Cd batteries can be recharged
when the instrument is operated by AC source. The LED for
indicating battery charging will light on. If the non-rechargeable
batteries (such as alkaline batteries) are installed in MT4080, set
the Battery Select Switch to "NORM" position for disconnecting
the charging circuit to the batteries.
Warning
The Battery Select Switch must be set in the "NORM"
position when using non-rechargeable batteries.
Non-rechargeable batteries may explode if the AC adapter is
used with non-rechargeable batteries. Warranty is voided if
this happened.
